Enhanced Auto Levels & Trendlines

Overview
The Enhanced Auto Levels & Trendlines (EAL&T) is a powerful, all-in-one indicator designed to automate the detection and visualization of key market structures. It combines auto-drawn trendlines, support/resistance levels with volume-based shadows and labels, and auto-flipping Fibonacci retracements/extensions. This tool helps traders identify potential reversals, breakouts, and targets without manual drawing.

Built on Pine Script v5, it uses pivot-based calculations for accuracy and includes customizable options for repainting, extensions, and sources. It's ideal for swing traders, scalpers, and analysts who want clean, dynamic charts.

Key Features

• Auto Trendlines: Detects bullish/bearish trends based on pivots, with breakout detection and optional extensions/targets.
  

• Auto Levels: Draws horizontal S/R levels from recent pivots, with "wick shadows" (boxes) highlighting volume strength and % buy/sell labels for sentiment.
  

• Fibonacci Levels: Auto-flips between latest pivot high/low, showing retracements (0.236–0.786) and extensions (1.272–3.0) with customizable styles.
  

• Customization: Override price sources, adjust lengths, colors, styles, and more. Supports repainting for real-time accuracy.
  

• Performance: Limited to 500 bars back and 500 lines for efficiency; no heavy computations.
  

• Visual Aids: Transparent shadows, extendable lines, and small labels for uncluttered charts.
  

How to Use
Step-by-Step Guide

Add to Chart: Load the indicator. Start with defaults.
Interpret Visuals:
Trendlines: Green (bullish/up), Red (bearish/down). Watch for breakouts – line "breaks" and extends if enabled.
Levels: Horizontal lines with shadows (boxes) showing wick strength. Green above price (resistance), Red below (support). Labels show % buy/sell sentiment.
Fibs: From latest swing low (0.0) to high (1.0). Use 0.5/0.618 for retracements; 1.272+ for targets. Flips automatically on trend change.

Customize for Your Strategy:
Volatile Markets (e.g., Crypto): Increase tl_length to 20+ for fewer false trends. Enable repainting for real-time.
Ranging Markets (e.g., Forex): Set override_source=true, custom_source=close for wick-ignoring pivots.
Fib Focus: Increase fib_extension_bars for longer projections. Hide trendlines if cluttered.
Levels Tuning: Shorten pivot lengths (e.g., 20) for intraday; lengthen (100+) for swings. Set shadow transparency to 100 to hide boxes.

Trading Ideas:
Breakout Trade: Buy on bull trendline break + Fib 0.618 confirmation.
Reversal: Sell at resistance level with high sell% label.
Targets: Use Fib extensions or trend targets for TP; levels for SL.
Combine: Overlay with MA crossover or volume for signals.

Tips & Troubleshooting:
Clutter? Toggle sections off or increase lengths.
No Lines? Ensure show_* is true; check chart history (needs 2x pivot length bars).
Repainting: Normal for real-time; disable for backtesting.
Custom Source: Test on demo – e.g., hl2 for median prices.
Updates: If lines don't extend, verify extend_bars > 0.
