Oil ETF VolumeDirexxion Daily has both 'bear' and 'bull' oil ETFs. This tracks the volume in both combined. It also tracks them individually: the bear ETF is the red line, and bull the green. NOTE: the color of the volume bars is determined by whatever ticker you're currently looking at, and whether current close is gt/lt previous close. It is intended to be used while looking at the USOIL chart. The colors will be inverted if you're looking at the 'bear' ETF! as the higher closes will actually mean price is going down :D

CE - 42MACRO Fixed Income and Macro This is Part 2 of 2 from the 42MACRO Recreation Series However, there will be a bonus Indicator coming soon! The CE - 42MACRO Fixed Income and Macro Table is a next level Macroeconomic and market analysis indicator. It aims to provide a probabilistic insight into the market realized GRID Macro regimes, track a multiplex of important Assets, Indices, Bonds and ETF's to derive extra market insights by showing the most important aggregates and their performance over multiple timeframes... and what that might mean for the whole market direction. For traders and especially investors, the unique functionalities will be of high value. Quick guide on how to use it: docs.google.com WARNING By the nature of the macro regimes, the outcomes are more accurate over longer Chart Timeframes (Week to Months). However, it is also a valuable tool to form an advanced, market realized, short to medium term bias. NOTE This Indicator is intended to be used alongside the 1nd part "CE - 42MACRO Equity Factor" for a more wholistic approach and higher accuracy. Methodology: The Equity Factor Table tracks specifically chosen Assets to identify their performance and add the combined performances together to visualize 42MACRO's GRID Equity Model. For this it uses the below Assets: Convertibles ( AMEX:CWB ) Leveraged Loans ( AMEX:BKLN ) High Yield Credit ( AMEX:HYG ) Preferreds ( NASDAQ:PFF ) Emerging Market US$ Bonds ( NASDAQ:EMB ) Long Bond ( NASDAQ:TLT ) 5-10yr Treasurys ( NASDAQ:IEF ) 5-10yr TIPS ( AMEX:TIP ) 0-5yr TIPS ( AMEX:STIP ) EM Local Currency Bonds ( AMEX:EMLC ) BDCs ( AMEX:BIZD ) Barclays Agg ( AMEX:AGG ) Investment Grade Credit ( AMEX:LQD ) MBS ( NASDAQ:MBB ) 1-3yr Treasurys ( NASDAQ:SHY ) Bitcoin ( AMEX:BITO ) Industrial Metals ( AMEX:DBB ) Commodities ( AMEX:DBC ) Gold ( AMEX:GLD ) Equity Volatility ( AMEX:VIXM ) Interest Rate Volatility ( AMEX:PFIX ) Energy ( AMEX:USO ) Precious Metals ( AMEX:DBP ) Agriculture ( AMEX:DBA ) US Dollar ( AMEX:UUP ) Inverse US Dollar ( AMEX:UDN ) Functionalities: Fixed Income and Macro Table Shows relative market Asset performance Comes with different Calculation options like RoC, Sharpe ratio, Sortino ratio, Omega ratio and Normalization Allows for advanced market (health) performance Provides the calculated, realized GRID market regimes Informs about "Risk ON" and "Risk OFF" market states Visuals - for your best experience only use one (+ BarColoring) at a time: You can visualize all important metrics: - GRID regimes of the currently chosen calculation type - Risk On/Risk Off with background colouring and additional +1/-1 values - a smoother GRID model - a smoother Risk On/ Risk Off metric - Barcoloring for enabled metric of the above If you have more suggestions, please write me Fixed Income and Macro: The visualisation of the relative performance of the different assets provides valuable information about the current market environment and the actual market performance. It furthermore makes it possible to obtain a deeper understanding of how the interconnected market works and makes it simple to identify the actual market direction, thus also providing all the information to derive overall market health, market strength or weakness. Utility: The Fixed Income and Macro Table is divided in 4 Columns which are the GRID regimes: Economic Growth: Goldilocks Reflation Economic Contraction: Inflation Deflation Top 5 Fixed Income/ Macro Factors: Are the values green for a specific Column? If so then the market reflects the corresponding GRID behavior. Bottom 5 Fixed Income/ Macro Factors: Are the values red for a specific Column? If so then the market reflects the corresponding GRID behavior. So if we have Goldilocks as current regime we would see green values in the Top 5 Goldilocks Cells and red values in the Bottom 5 Goldilocks Cells. You will find that Reflation will look similar, as it is also a sign of Economic Growth. Same is the case for the two Contraction regimes. ****** This Indicator again is based to a majority on 42MACRO's models. I only brought them into TV and added things on top of it. If you have questions or need a more in-depth guide DM me. GM

Yang-Zhang Volatility (YZVol) by CoryP1990 – Quant ToolkitThe Yang-Zhang Volatility (YZVol) estimator measures realized volatility using both overnight gaps and intraday moves. It combines three components: overnight returns, open-to-close returns, and the Rogers–Satchell term, weighted by Zhang’s k to reduce bias. How to read it Line color: Green when YZVol is rising (volatility expansion), Red when falling (volatility compression). Background: Green tint = above High-vol threshold (active regime). Red tint = below Low-vol threshold (quiet regime). Units: Displays Daily % by default on any timeframe (values are normalized to daily). An optional toggle shows Annualized % (√252 × Daily %). Typical uses Spot transitions between quiet and active regimes. Compare realized vol vs implied vol or a risk-target. Adapt position sizing to volatility clustering. Defaults Length = 20 High-vol threshold = 5% (Daily) Low-vol threshold = 1% (Daily) Optional: Annualized % display Example — SPY (1D) During the 2020 crash, YZVol surged to 5.8 % per day, capturing the height of pandemic-era volatility before compressing into a calm regime through 2021. Volatility re-expanded in 2022 due to reinflamed COVID fears and gradually stabilized through 2023. A sharp, liquidity-driven volatility event in August 2024 caused another brief YZVol surge, reflecting the historic one-day VIX spike triggered by market-wide risk-off flows and thin pre-market liquidity. A second, policy-driven expansion followed in April–May 2025, coinciding with the renewed U.S.–China tariff conflict and a sharp equity pullback. Since mid-2025, YZVol has settled near 1 % per day, with the red background confirming that realized volatility has once again compressed into a quiet, low-risk regime. Part of the Quant Toolkit — transparent, open-source indicators for modern quantitative analysis. Built by CoryP1990.

VIX Regime AnalyzerVIX Regime Analyzer The VIX Regime Analyzer is an analytical tool that examines historical VIX patterns to provide insights into how your asset typically performs under similar volatility conditions. Key Features: Historical Pattern Matching: Automatically scans up to 1,000 bars of history to find all periods when VIX was at levels similar to today, using customizable tolerance ranges (absolute or percentage-based). Forward-Looking Statistics: For each VIX regime match, calculates what actually happened to your asset over the next 1, 5, 10, and 20 trading days, providing both average returns and probability of positive outcomes. Regime Classification System: Intelligently categorizes the current market environment as bullish or bearish: Visual Historical Context: Background shading throughout your chart highlights every historical period when VIX matched current levels, color-coded by subsequent performance (green for gains, red for losses). User Inputs: VIX Level Tolerance (+/-): How closely VIX must match (default: ±5 points) Use Relative Tolerance (%): Switch to percentage-based matching for consistency across different VIX levels Lookback Period: How many bars to analyze Highlight Historical VIX Matches: Toggle background highlighting of past matching periods The Data Table The statistics box appears in the right handside of your chart and contains three main sections: Section 1: VIX REGIME Current VIX: The live VIX closing price Range: The tolerance band being searched (e.g., if VIX is 18 with ±5 tolerance, range is 13-23) Historical Samples: Number of matching periods found in the lookback window (minimum 10 required for statistical validity) Section 2: FORWARD RETURN Shows the average percentage change in your asset over different timeframes following similar VIX levels: Avg Next Day: What typically happened by the next trading session Avg Next 5 Days: Average 5-day forward performance Avg Next 10 Days: Average 10-day forward performance Avg Next 20 Days: Average 20-day forward performance (approximately 1 month) Section 3: PROBABILITY UP Shows the win rate - the percentage of times your asset closed higher after VIX matched current levels: Next Day: Probability of being up the next session Next 5 Days: Probability of being up after 5 days Next 10 Days: Probability of being up after 10 days Next 20 Days: Probability of being up after 20 days Colors: 🟢 Green: Bullish regimes (various strengths) 🔴 Red: Bearish regimes (various strengths) 🟡 Yellow: Choppy/uncertain regime When "Highlight Historical VIX Matches" is enabled: Scroll back through your chart and you'll see colored backgrounds highlighting every period when VIX matched today's level. The color tells you whether that match led to gains (green) or losses (red). This provides instant visual pattern recognition - you can quickly see if similar VIX levels historically led to bullish or bearish outcomes. Practical Example: If you see that most historical periods with similar VIX levels are highlighted in green, it suggests the current VIX level has historically been a bullish signal for your asset. How The Indicator Makes Decisions The regime classification uses both magnitude AND probability to avoid false signals: Example of Strong Classification: Average 5-day return: +1.5% Win rate: 65% Result: STRONG BULLISH (both high return and high probability) Example of Weak Signal: Average 5-day return: +2.0% Win rate: 35% Result: CHOPPY (high average but low consistency = unreliable) This dual-factor approach ensures the indicator doesn't mislead you with regimes that had a few huge winners but mostly losers, or vice versa. Best Practices Combine with your existing strategy: Use this as a regime filter rather than standalone signals Check sample size: More historical matches = more reliable statistics Consider multiple timeframes: If 5-day and 20-day metrics disagree, proceed with caution Asset-specific tuning: Different assets may require different tolerance settings VIX spikes: The indicator is particularly useful during VIX spikes to understand if panic is justified What Makes This Different Unlike simple VIX indicators that just plot the fear index, this tool: Quantifies the actual impact of VIX levels on YOUR specific asset Provides probability-based forecasts rather than subjective interpretation Shows historical context visually so you can see patterns at a glance Uses rigorous statistical criteria to avoid false regime classifications

Composite Buy/Sell Score [-100 to +100] by LMComposite Buy/Sell Score (Stabilized + Sensitivity) by LM Description: This indicator calculates a composite trend strength score ranging from -100 to +100 by combining multiple popular technical indicators into a single, smoothed metric. It is designed to give traders a clear view of bullish and bearish trends, while filtering out short-term noise. The score incorporates signals from: PPO (Percentage Price Oscillator) – measures momentum via the difference between fast and slow EMAs. ADX (Average Directional Index) – detects trend strength. RSI (Relative Strength Index) – identifies short-term momentum swings. Stochastic RSI – measures RSI momentum and speed of change. MACD (Moving Average Convergence Divergence) – detects momentum shifts using EMA crossovers. Williams %R – highlights overbought/oversold conditions. Each component is weighted, smoothed, and optionally confirmed across a configurable number of bars, producing a stabilized composite score that reacts more reliably to significant trend changes. Key Features: Smoothed Composite Score The final score is smoothed using an EMA to reduce volatility and emphasize meaningful trends. A Sensitivity Multiplier allows traders to exaggerate the score for stronger trend signals or dampen it for quieter markets. Customizable Inputs You can adjust each indicator’s parameters, smoothing lengths, and confirm bars to suit your preferred timeframe and trading style. The sensitivity multiplier allows fine-tuning the responsiveness of the trend line without changing underlying indicator calculations. Visual Representation Score Line: Green for positive (bullish) trends, red for negative (bearish) trends, gray near neutral. Reference Lines: 0 = neutral +100 = maximum bullish -100 = maximum bearish Adaptive Background: Optionally highlights the background intensity proportional to trend strength. Strong green for bullish trends, strong red for bearish trends. Multi-Indicator Integration Combines momentum, trend, and overbought/oversold signals into a single metric. Helps identify clear entry/exit trends while avoiding whipsaw noise common in individual indicators. Recommended Use: Trend Identification: Look for sustained movement above 0 for bullish trends and below 0 for bearish trends. Exaggerated Trends: Use the Sensitivity Multiplier to emphasize strong trends. Filtering Noise: The smoothed score and confirmBars settings help reduce false signals from minor price fluctuations. Inputs Overview: Input Purpose PPO Fast EMA / Slow EMA / Signal Controls PPO momentum sensitivity ADX Length / Threshold Detects trend strength RSI Length / Overbought / Oversold Measures short-term momentum Stoch RSI Length / %K / %D Measures speed of RSI changes MACD Fast / Slow / Signal Measures momentum crossover Williams %R Length Detects overbought/oversold conditions Final Score Smoothing Length EMA smoothing for final composite score Confirm Bars for Each Signal Number of bars used to confirm individual indicator signals Sensitivity Multiplier Scales the final composite score for exaggerated trend response Highlight Background by Trend Strength Enables adaptive background coloring This indicator is suitable for traders looking for a single, clear trend metric derived from multiple indicators. It can be applied to any timeframe and can help identify both strong and emerging trends in the market.

Ultimate Oscillator (ULTOSC)The Ultimate Oscillator (ULTOSC) is a technical momentum indicator developed by Larry Williams that combines three different time periods to reduce the volatility and false signals common in single-period oscillators. By using a weighted average of three Stochastic-like calculations across short, medium, and long-term periods, the Ultimate Oscillator provides a more comprehensive view of market momentum while maintaining sensitivity to price changes. The indicator addresses the common problem of oscillators being either too sensitive (generating many false signals) or too slow (missing opportunities). By incorporating multiple timeframes with decreasing weights for longer periods, ULTOSC attempts to capture both short-term momentum shifts and longer-term trend strength, making it particularly valuable for identifying divergences and potential reversal points. ## Core Concepts * **Multi-timeframe analysis:** Combines three different periods (typically 7, 14, 28) to capture various momentum cycles * **Weighted averaging:** Assigns higher weights to shorter periods for responsiveness while including longer periods for stability * **Buying pressure focus:** Measures the relationship between closing price and the true range rather than just high-low range * **Divergence detection:** Particularly effective at identifying momentum divergences that precede price reversals * **Normalized scale:** Oscillates between 0 and 100, with clear overbought/oversold levels ## Common Settings and Parameters | Parameter | Default | Function | When to Adjust | |-----------|---------|----------|---------------| | Fast Period | 7 | Short-term momentum calculation | Lower (5-6) for more sensitivity, higher (9-12) for smoother signals | | Medium Period | 14 | Medium-term momentum calculation | Adjust based on typical swing duration in the market | | Slow Period | 28 | Long-term momentum calculation | Higher values (35-42) for longer-term position trading | | Fast Weight | 4.0 | Weight applied to fast period | Higher weight increases short-term sensitivity | | Medium Weight | 2.0 | Weight applied to medium period | Adjust to balance medium-term influence | | Slow Weight | 1.0 | Weight applied to slow period | Usually kept at 1.0 as the baseline weight | **Pro Tip:** The classic 7/14/28 periods with 4/2/1 weights work well for most markets, but consider using 5/10/20 with adjusted weights for faster markets or 14/28/56 for longer-term analysis. ## Calculation and Mathematical Foundation **Simplified explanation:** The Ultimate Oscillator calculates three separate "buying pressure" ratios using different time periods, then combines them using weighted averaging. Buying pressure is defined as the close minus the true low, divided by the true range. **Technical formula:** ``` BP = Close - Min(Low, Previous Close) TR = Max(High, Previous Close) - Min(Low, Previous Close) BP_Sum_Fast = Sum(BP, Fast Period) TR_Sum_Fast = Sum(TR, Fast Period) Raw_Fast = 100 × (BP_Sum_Fast / TR_Sum_Fast) BP_Sum_Medium = Sum(BP, Medium Period) TR_Sum_Medium = Sum(TR, Medium Period) Raw_Medium = 100 × (BP_Sum_Medium / TR_Sum_Medium) BP_Sum_Slow = Sum(BP, Slow Period) TR_Sum_Slow = Sum(TR, Slow Period) Raw_Slow = 100 × (BP_Sum_Slow / TR_Sum_Slow) ULTOSC = 100 × / (Fast_Weight + Medium_Weight + Slow_Weight) ``` Where: - BP = Buying Pressure - TR = True Range - Fast Period = 7, Medium Period = 14, Slow Period = 28 (defaults) - Fast Weight = 4, Medium Weight = 2, Slow Weight = 1 (defaults) > 🔍 **Technical Note:** The implementation uses efficient circular buffers for all three period calculations, maintaining O(1) time complexity per bar. The algorithm properly handles true range calculations including gaps and ensures accurate buying pressure measurements across all timeframes. ## Interpretation Details ULTOSC provides several analytical perspectives: * **Overbought/Oversold conditions:** Values above 70 suggest overbought conditions, below 30 suggest oversold conditions * **Momentum direction:** Rising ULTOSC indicates increasing buying pressure, falling indicates increasing selling pressure * **Divergence analysis:** Divergences between ULTOSC and price often precede significant reversals * **Trend confirmation:** ULTOSC direction can confirm or question the prevailing price trend * **Signal quality:** Extreme readings (>80 or <20) indicate strong momentum that may be unsustainable * **Multiple timeframe consensus:** When all three underlying periods agree, signals are typically more reliable ## Trading Applications **Primary Uses:** - **Divergence trading:** Identify when momentum diverges from price for reversal signals - **Overbought/oversold identification:** Find potential entry/exit points at extreme levels - **Trend confirmation:** Validate breakouts and trend continuations - **Momentum analysis:** Assess the strength of current price movements **Advanced Strategies:** - **Multi-divergence confirmation:** Look for divergences across multiple timeframes - **Momentum breakouts:** Trade when ULTOSC breaks above/below key levels with volume - **Swing trading entries:** Use oversold/overbought levels for swing position entries - **Trend strength assessment:** Evaluate trend quality using momentum consistency ## Signal Combinations **Strong Bullish Signals:** - ULTOSC rises from oversold territory (<30) with positive price divergence - ULTOSC breaks above 50 after forming a base near 30 - All three underlying periods show increasing buying pressure **Strong Bearish Signals:** - ULTOSC falls from overbought territory (>70) with negative price divergence - ULTOSC breaks below 50 after forming a top near 70 - All three underlying periods show decreasing buying pressure **Divergence Signals:** - **Bullish divergence:** Price makes lower lows while ULTOSC makes higher lows - **Bearish divergence:** Price makes higher highs while ULTOSC makes lower highs - **Hidden bullish divergence:** Price makes higher lows while ULTOSC makes lower lows (trend continuation) - **Hidden bearish divergence:** Price makes lower highs while ULTOSC makes higher highs (trend continuation) ## Comparison with Related Oscillators | Indicator | Periods | Focus | Best Use Case | |-----------|---------|-------|---------------| | **Ultimate Oscillator** | 3 periods | Buying pressure | Divergence detection | | **Stochastic** | 1-2 periods | Price position | Overbought/oversold | | **RSI** | 1 period | Price momentum | Momentum analysis | | **Williams %R** | 1 period | Price position | Short-term signals | ## Advanced Configurations **Fast Trading Setup:** - Fast: 5, Medium: 10, Slow: 20 - Weights: 4/2/1, Thresholds: 75/25 **Standard Setup:** - Fast: 7, Medium: 14, Slow: 28 - Weights: 4/2/1, Thresholds: 70/30 **Conservative Setup:** - Fast: 14, Medium: 28, Slow: 56 - Weights: 3/2/1, Thresholds: 65/35 **Divergence Focused:** - Fast: 7, Medium: 14, Slow: 28 - Weights: 2/2/2, Thresholds: 70/30 ## Market-Specific Adjustments **Volatile Markets:** - Use longer periods (10/20/40) to reduce noise - Consider higher threshold levels (75/25) - Focus on extreme readings for signal quality **Trending Markets:** - Emphasize divergence analysis over absolute levels - Look for momentum confirmation rather than reversal signals - Use hidden divergences for trend continuation **Range-Bound Markets:** - Standard overbought/oversold levels work well - Trade reversals from extreme levels - Combine with support/resistance analysis ## Limitations and Considerations * **Lagging component:** Contains inherent lag due to multiple moving average calculations * **Complex calculation:** More computationally intensive than single-period oscillators * **Parameter sensitivity:** Performance varies significantly with different period/weight combinations * **Market dependency:** Most effective in trending markets with clear momentum patterns * **False divergences:** Not all divergences lead to significant price reversals * **Whipsaw potential:** Can generate conflicting signals in choppy markets ## Best Practices **Effective Usage:** - Focus on divergences rather than absolute overbought/oversold levels - Combine with trend analysis for context - Use multiple timeframe analysis for confirmation - Pay attention to the speed of momentum changes **Common Mistakes:** - Over-relying on overbought/oversold levels in strong trends - Ignoring the underlying trend direction - Using inappropriate period settings for the market being analyzed - Trading every divergence without additional confirmation **Signal Enhancement:** - Combine with volume analysis for confirmation - Use price action context (support/resistance levels) - Consider market volatility when setting thresholds - Look for convergence across multiple momentum indicators ## Historical Context and Development The Ultimate Oscillator was developed by Larry Williams and introduced in his 1985 article "The Ultimate Oscillator" in Technical Analysis of Stocks and Commodities magazine. Williams designed it to address the limitations of single-period oscillators by: - Reducing false signals through multi-timeframe analysis - Maintaining sensitivity to short-term momentum changes - Providing more reliable divergence signals - Creating a more robust momentum measurement tool The indicator has become a standard tool in technical analysis, particularly valued for its divergence detection capabilities and its balanced approach to momentum measurement. ## References * Williams, L.

Standardization (Z-score)Standardization, often referred to as Z-score normalization, is a data preprocessing technique that rescales data to have a mean of 0 and a standard deviation of 1. The resulting values, known as Z-scores, indicate how many standard deviations an individual data point is from the mean of the dataset (or a rolling sample of it). This indicator calculates and plots the Z-score for a given input series over a specified lookback period. It is a fundamental tool for statistical analysis, outlier detection, and preparing data for certain machine learning algorithms. ## Core Concepts * **Standardization:** The process of transforming data to fit a standard normal distribution (or more generally, to have a mean of 0 and standard deviation of 1). * **Z-score (Standard Score):** A dimensionless quantity that represents the number of standard deviations by which a data point deviates from the mean of its sample. The formula for a Z-score is: `Z = (x - μ) / σ` Where: * `x` is the individual data point (e.g., current value of the source series). * `μ` (mu) is the mean of the sample (calculated over the lookback period). * `σ` (sigma) is the standard deviation of the sample (calculated over the lookback period). * **Mean (μ):** The average value of the data points in the sample. * **Standard Deviation (σ):** A measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean, while a high standard deviation indicates that the values are spread out over a wider range. ## Common Settings and Parameters | Parameter | Type | Default | Function | When to Adjust | | :-------------- | :----------- | :------ | :------------------------------------------------------------------------------------------------------ | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Source | series float | close | The input data series (e.g., price, volume, indicator values). | Choose the series you want to standardize. | | Lookback Period | int | 20 | The number of bars (sample size) used for calculating the mean (μ) and standard deviation (σ). Min 2. | A larger period provides more stable estimates of μ and σ but will be less responsive to recent changes. A shorter period is more reactive. `minval` is 2 because `ta.stdev` requires it. | **Pro Tip:** Z-scores are excellent for identifying anomalies or extreme values. For instance, applying Standardization to trading volume can help quickly spot days with unusually high or low activity relative to the recent norm (e.g., Z-score > 2 or < -2). ## Calculation and Mathematical Foundation The Z-score is calculated for each bar as follows, using a rolling window defined by the `Lookback Period`: 1. **Calculate Mean (μ):** The simple moving average (`ta.sma`) of the `Source` data over the specified `Lookback Period` is calculated. This serves as the sample mean `μ`. `μ = ta.sma(Source, Lookback Period)` 2. **Calculate Standard Deviation (σ):** The standard deviation (`ta.stdev`) of the `Source` data over the same `Lookback Period` is calculated. This serves as the sample standard deviation `σ`. `σ = ta.stdev(Source, Lookback Period)` 3. **Calculate Z-score:** * If `σ > 0`: The Z-score is calculated using the formula: `Z = (Current Source Value - μ) / σ` * If `σ = 0`: This implies all values in the lookback window are identical (and equal to the mean). In this case, the Z-score is defined as 0, as the current source value is also equal to the mean. * If `σ` is `na` (e.g., insufficient data in the lookback period), the Z-score is `na`. > 🔍 **Technical Note:** > * The `Lookback Period` must be at least 2 for `ta.stdev` to compute a valid standard deviation. > * The Z-score calculation uses the sample mean and sample standard deviation from the rolling lookback window. ## Interpreting the Z-score * **Magnitude and Sign:** * A Z-score of **0** means the data point is identical to the sample mean. * A **positive Z-score** indicates the data point is above the sample mean. For example, Z = 1 means the point is 1 standard deviation above the mean. * A **negative Z-score** indicates the data point is below the sample mean. For example, Z = -1 means the point is 1 standard deviation below the mean. * **Typical Range:** For data that is approximately normally distributed (bell-shaped curve): * About 68% of Z-scores fall between -1 and +1. * About 95% of Z-scores fall between -2 and +2. * About 99.7% of Z-scores fall between -3 and +3. * **Outlier Detection:** Z-scores significantly outside the -2 to +2 range, and especially outside -3 to +3, are often considered outliers or extreme values relative to the recent historical data in the lookback window. * **Volatility Indication:** When applied to price, large absolute Z-scores can indicate moments of high volatility or significant deviation from the recent price trend. The indicator plots horizontal lines at ±1, ±2, and ±3 standard deviations to help visualize these common thresholds. ## Common Applications 1. **Outlier Detection:** Identifying data points that are unusual or extreme compared to the rest of the sample. This is a primary use in financial markets for spotting abnormal price moves, volume spikes, etc. 2. **Comparative Analysis:** Allows for comparison of scores from different distributions that might have different means and standard deviations. For example, comparing the Z-score of returns for two different assets. 3. **Feature Scaling in Machine Learning:** Standardizing features to have a mean of 0 and standard deviation of 1 is a common preprocessing step for many machine learning algorithms (e.g., SVMs, logistic regression, neural networks) to improve performance and convergence. 4. **Creating Normalized Oscillators:** The Z-score itself can be used as a bounded (though not strictly between -1 and +1) oscillator, indicating how far the current price has deviated from its moving average in terms of standard deviations. 5. **Statistical Process Control:** Used in quality control charts to monitor if a process is within expected statistical limits. ## Limitations and Considerations * **Assumption of Normality for Probabilistic Interpretation:** While Z-scores can always be calculated, the probabilistic interpretations (e.g., "68% of data within ±1σ") strictly apply to normally distributed data. Financial data is often not perfectly normal (e.g., it can have fat tails). * **Sensitivity of Mean and Standard Deviation to Outliers:** The sample mean (μ) and standard deviation (σ) used in the Z-score calculation can themselves be influenced by extreme outliers within the lookback period. This can sometimes mask or exaggerate the Z-score of other points. * **Choice of Lookback Period:** The Z-score is highly dependent on the `Lookback Period`. A short period makes it very sensitive to recent fluctuations, while a long period makes it smoother and less responsive. The appropriate period depends on the analytical goal. * **Stationarity:** For time series data, Z-scores are calculated based on a rolling window. This implicitly assumes some level of local stationarity (i.e., the mean and standard deviation are relatively stable within the window).

Triangular Moving Average (TRIMA)The Triangular Moving Average (TRIMA) is a technical indicator that applies a triangular weighting scheme to price data, providing enhanced smoothing compared to simpler moving averages. Originating in the early 1970s as technical analysts sought more effective noise filtering methods, the TRIMA was first popularized through the work of market technician Arthur Merrill. Its formal mathematical properties were established in the 1980s, and the indicator gained widespread adoption in the 1990s as computerized charting became standard. TRIMA effectively filters out market noise while maintaining important trends through its unique center-weighted calculation method. ## Core Concepts * **Double-smoothing process:** TRIMA can be viewed as applying a simple moving average twice, creating more effective noise filtering * **Triangular weighting:** Uses a symmetrical weight distribution that emphasizes central data points and reduces emphasis toward both ends * **Constant-time implementation:** Two $O(1)$ SMA passes with circular buffers preserve exact triangular weights while keeping update cost constant per bar * **Market application:** Particularly effective for identifying the underlying trend in noisy market conditions where standard moving averages generate too many false signals * **Timeframe flexibility:** Works across multiple timeframes, with longer periods providing cleaner trend signals in higher timeframes The core innovation of TRIMA is its unique triangular weighting scheme, which can be viewed either as a specialized weight distribution or as a twice-applied simple moving average with adjusted period. This creates more effective noise filtering without the excessive lag penalty typically associated with longer-period averages. The symmetrical nature of the weight distribution ensures zero phase distortion, preserving the timing of important market turning points. ## Common Settings and Parameters | Parameter | Default | Function | When to Adjust | |-----------|---------|----------|---------------| | Length | 14 | Controls the lookback period | Increase for smoother signals in volatile markets, decrease for responsiveness | | Source | close | Price data used for calculation | Consider using hlc3 for a more balanced price representation | **Pro Tip:** For a good balance between smoothing and responsiveness, try using a TRIMA with period N instead of an SMA with period 2N - you'll get similar smoothing characteristics but with less lag. ## Calculation and Mathematical Foundation **Simplified explanation:** TRIMA calculates a weighted average of prices where the weights form a triangle shape. The middle prices get the most weight, and weights gradually decrease toward both the recent and older ends. This creates a smooth filter that effectively removes random price fluctuations while preserving the underlying trend. **Technical formula:** TRIMA = Σ(Price × Weight ) / Σ(Weight ) Where the triangular weights form a symmetric pattern: - Weight = min(i, n-1-i) + 1 - Example for n=5: weights = - Example for n=4: weights = Alternatively, TRIMA can be calculated as: TRIMA(source, p) = SMA(SMA(source, (p+1)/2), (p+1)/2) > 🔍 **Technical Note:** The double application of SMA explains why TRIMA provides better smoothing than a single SMA or WMA. This approach effectively applies smoothing twice with optimal period adjustment, creating a -18dB/octave roll-off in the frequency domain compared to -6dB/octave for a simple moving average, and the current implementation achieves $O(1)$ complexity through circular buffers and NA-safe warmup compensation. ## Interpretation Details TRIMA can be used in various trading strategies: * **Trend identification:** The direction of TRIMA indicates the prevailing trend * **Signal generation:** Crossovers between price and TRIMA generate trade signals with fewer false alarms than SMA * **Support/resistance levels:** TRIMA can act as dynamic support during uptrends and resistance during downtrends * **Trend strength assessment:** Distance between price and TRIMA can indicate trend strength * **Multiple timeframe analysis:** Using TRIMAs with different periods can confirm trends across different timeframes ## Limitations and Considerations * **Market conditions:** Like all moving averages, less effective in choppy, sideways markets * **Lag factor:** More lag than WMA or EMA due to center-weighted emphasis * **Limited adaptability:** Fixed weighting scheme cannot adapt to changing market volatility * **Response time:** Takes longer to reflect sudden price changes than directionally-weighted averages * **Complementary tools:** Best used with momentum oscillators or volume indicators for confirmation ## References * Ehlers, John F.

Savitzky-Golay Filter (SGF)The Savitzky-Golay Filter (SGF) is a digital filter that performs local polynomial regression on a series of values to determine the smoothed value for each point. Developed by Abraham Savitzky and Marcel Golay in 1964, it is particularly effective at preserving higher moments of the data while reducing noise. This implementation provides a practical adaptation for financial time series, offering superior preservation of peaks, valleys, and other important market structures that might be distorted by simpler moving averages. ## Core Concepts * **Local polynomial fitting:** Fits a polynomial of specified order to a sliding window of data points * **Moment preservation:** Maintains higher statistical moments (peaks, valleys, inflection points) * **Optimized coefficients:** Uses pre-computed coefficients for common polynomial orders * **Adaptive weighting:** Weight distribution varies based on polynomial order and window size * **Market application:** Particularly effective for preserving significant price movements while filtering noise The core innovation of the Savitzky-Golay filter is its ability to smooth data while preserving important features that are often flattened by other filtering methods. This makes it especially valuable for technical analysis where maintaining the shape of price patterns is crucial. ## Common Settings and Parameters | Parameter | Default | Function | When to Adjust | |-----------|---------|----------|---------------| | Window Size | 11 | Number of points used in local fitting (must be odd) | Increase for smoother output, decrease for better feature preservation | | Polynomial Order | 2 | Order of fitting polynomial (2 or 4) | Use 2 for general smoothing, 4 for better peak preservation | | Source | close | Price data used for calculation | Consider using hlc3 for more stable fitting | **Pro Tip:** A window size of 11 with polynomial order 2 provides a good balance between smoothing and feature preservation. For sharper peaks and valleys, use order 4 with a smaller window size. ## Calculation and Mathematical Foundation **Simplified explanation:** The filter fits a polynomial of specified order to a moving window of price data. The smoothed value at each point is computed from this local fit, effectively removing noise while preserving the underlying shape of the data. **Technical formula:** For a window of size N and polynomial order M, the filtered value is: y = Σ(c_i × x ) Where: - c_i are the pre-computed filter coefficients - x are the input values in the window - Coefficients depend on window size N and polynomial order M > 🔍 **Technical Note:** The implementation uses optimized coefficient calculations for orders 2 and 4, which cover most practical applications while maintaining computational efficiency. ## Interpretation Details The Savitzky-Golay filter can be used in various trading strategies: * **Pattern recognition:** Preserves chart patterns while removing noise * **Peak detection:** Maintains amplitude and width of significant peaks * **Trend analysis:** Smooths price movement without distorting important transitions * **Divergence trading:** Better preservation of local maxima and minima * **Volatility analysis:** Accurate representation of price movement dynamics ## Limitations and Considerations * **Computational complexity:** More intensive than simple moving averages * **Edge effects:** First and last few points may show end effects * **Parameter sensitivity:** Performance depends on appropriate window size and order selection * **Data requirements:** Needs sufficient points for polynomial fitting * **Complementary tools:** Best used with volume analysis and momentum indicators ## References * Savitzky, A., Golay, M.J.E.

Bilateral Filter (BILATERAL)The Bilateral Filter is an edge-preserving smoothing technique that combines spatial filtering with intensity filtering to achieve noise reduction while maintaining significant price structure. Originally developed in computer vision for image processing, this adaptive filter has been adapted for financial time series analysis to provide superior smoothing that preserves important market transitions. The filter intelligently reduces noise in stable price regions while preserving sharp transitions like breakouts, reversals, and other significant market structures that would be blurred by conventional filters. ## Core Concepts * **Dual-domain filtering:** Combines traditional time-based (spatial) filtering with value-based (range) filtering for adaptive smoothing * **Edge preservation:** Maintains important price transitions while aggressively smoothing areas of minor fluctuation * **Adaptive processing:** Automatically adjusts filtering strength based on local price characteristics The core innovation of the Bilateral Filter is its ability to distinguish between random noise and significant price movements. Unlike conventional filters that smooth everything equally, Bilateral filtering preserves major price transitions by reducing the influence of price points that differ significantly from the current price, effectively preserving market structure while still eliminating noise. ## Common Settings and Parameters | Parameter | Default | Function | When to Adjust | |-----------|---------|----------|---------------| | Length | 14 | Controls the lookback window size | Increase for more context in filtering decisions, decrease for quicker response | | Sigma_S_Ratio | 0.3 | Controls spatial (time) weighting | Lower values emphasize recent bars, higher values distribute influence more evenly | | Sigma_R_Mult | 2.0 | Controls range (price) sensitivity | Lower values increase edge preservation, higher values increase smoothing | | Source | close | Price data used for calculation | Consider using hlc3 for a more balanced price representation | **Pro Tip:** For breakout trading strategies, try reducing Sigma_R_Mult to 1.0-1.5 to make the filter more sensitive to significant price moves, allowing it to preserve breakout signals while still filtering noise. ## Calculation and Mathematical Foundation **Simplified explanation:** The Bilateral Filter calculates a weighted average of nearby prices, where the weights depend on two factors: how far away in time the price point is (spatial weight) and how different the price value is (range weight). Points that are close in time AND similar in value get the highest weight. This means stable price regions get smoothed while significant changes are preserved. **Technical formula:** BF = (1 / Wp) × Σ_{q ∈ S} G_s(||p - q||) × G_r(|I - I |) × I Where: - G_s is the spatial Gaussian kernel: exp(-||p - q||² / (2 × σ_s²)) - G_r is the range Gaussian kernel: exp(-|I - I |² / (2 × σ_r²)) - Wp is the normalization factor (sum of all weights) > 🔍 **Technical Note:** The sigma_r parameter is typically calculated dynamically based on local price volatility (standard deviation) to provide adaptive filtering - this automatically adjusts filtering strength based on market conditions. ## Interpretation Details The Bilateral Filter can be applied in various trading contexts: * **Trend identification:** Reveals cleaner underlying price direction by removing noise while preserving trend changes * **Support/resistance identification:** Provides clearer price levels by preserving significant turning points * **Pattern recognition:** Maintains critical chart patterns while eliminating distracting minor fluctuations * **Breakout trading:** Preserves sharp price transitions for more reliable breakout signals * **Pre-processing:** Can be used as an initial filter before applying other technical indicators to reduce false signals ## Limitations and Considerations * **Computational complexity:** More intensive calculations than traditional linear filters * **Parameter sensitivity:** Performance highly dependent on proper parameter selection * **Non-linearity:** Non-linear behavior may produce unexpected results in certain market conditions * **Interpretation adjustment:** Requires different interpretation than conventional moving averages * **Complementary tools:** Best used alongside volume analysis and traditional indicators for confirmation ## References * Tomasi, C. and Manduchi, R.
