80% EDGE RULE - TPO BASED
═════════════════════════════════════════════════════════════
█ OVERVIEW
The 80% Edge Rule is a high-probability Market Profile concept that identifies when price is likely to traverse the prior session's Value Area. This indicator automates the detection, confirmation, and tracking of 80% EDGE Rule setups using true TPO (Time Price Opportunity) calculations—not volume profile.
When price opens outside the previous day's Value Area and then re-enters and is "accepted" back inside, there is an 80% statistical probability that price will travel to the opposite side of the Value Area. This indicator does all the heavy lifting: calculating the prior session's Value Area, detecting valid setups, confirming acceptance, and tracking progress toward the target.
█ THE 80% EDGE RULE EXPLAINED
The 80% Edge Rule is based on Market Profile theory developed by J. Peter Steidlmayer at the Chicago Board of Trade. The rule states:
❶ If price OPENS OUTSIDE the prior day's Value Area...
❷ And then ENTERS and is ACCEPTED back into the Value Area...
❸ There is an 80% chance price will rotate to the OTHER SIDE of the Value Area.
"Acceptance" is defined as price spending TWO OR MORE TPO periods (typically 30-minute blocks) inside the Value Area. This indicates that the market has accepted these prices as fair value, and the auction process will likely continue through to the opposite boundary.
BULLISH SETUP: Price opens BELOW the prior VAL → Enters and is accepted → Target is VAH
BEARISH SETUP: Price opens ABOVE the prior VAH → Enters and is accepted → Target is VAL
█ HOW THIS INDICATOR WORKS
This indicator performs several automated functions:
1. TPO VALUE AREA CALCULATION
• Analyzes the prior RTH (Regular Trading Hours) session
• Builds a true TPO distribution using 30-minute time blocks
• Each price level receives +1 TPO for each period it was touched
• Calculates POC (Point of Control) as the price with highest TPO count
• Expands from POC using the CME/CBOT standard "two-price" method until 70% of TPOs are captured
• This defines VAH (Value Area High) and VAL (Value Area Low)
2. SETUP DETECTION
• Monitors the RTH open (default 9:30 AM ET)
• Detects if price opened outside the prior Value Area
• Determines setup direction (Bullish or Bearish)
3. ACCEPTANCE MONITORING
• Tracks TPO blocks where price remains inside the Value Area
• Confirms setup when required number of blocks is reached (default: 2)
• Resets count if price exits VA before confirmation
4. TARGET & INVALIDATION TRACKING
• Monitors for target completion (opposite VA boundary)
• Monitors for invalidation (price moves beyond entry VA boundary + buffer)
• Visual feedback on outcome
█ VISUAL ELEMENTS

█ ALERTS
This indicator includes three configurable alerts:
① SETUP CONFIRMED
• Triggers when acceptance criteria is met
• Includes entry price and target price in alert message
② TARGET HIT
• Triggers when price reaches the opposite VA boundary
• Confirms successful completion of the 80% Rule setup
③ INVALIDATED
• Triggers when price moves beyond the invalidation threshold
• Signals that the setup has failed
To enable alerts:
1. Ensure "Enable Alerts" is checked in indicator settings
2. Right-click on the indicator → "Add Alert"
3. Select the condition you want to be alerted on
4. Configure notification method (popup, email, webhook, etc.)
█ RECOMMENDED USAGE
TIMEFRAME:
• Best used on 5-minute, 15-minute, or 30-minute charts
• The chart timeframe should divide evenly into 30 minutes
• Ensure sufficient historical bars are loaded for prior session calculation
BEST PRACTICES:
• Wait for full confirmation (2 TPO blocks inside VA) before considering entry
• Use the target line as your profit objective
• Consider the invalidation level for stop-loss placement
• Monitor the dashboard for real-time setup status
• Combine with other confluence factors (order flow, support/resistance, etc.)
IMPORTANT NOTES:
• This indicator calculates TRUE TPO-based Value Area, not volume profile
• Prior day VA is recalculated at each new session
• The 80% Rule is a statistical tendency, not a guarantee
• Always use proper risk management
