HIPA - High IRL Probability Areas [Pro]

Overview
HIPA (High IRL Probability Areas) visualizes statistically derived Internal Range Liquidity (IRL) zones — price areas that have historically shown a higher tendency for revisit or interaction within an intraday session.
When a candle breaks a higher-timeframe reference bar’s high or low, HIPA plots a draw line at the opposite extreme of that bar, highlighting where liquidity is most likely to rest.
Each line displays a live, time-conditioned probability (CH) of being revisited before session end, plus an optional End-of-Day (EOD) probability.

HIPA provides statistical context on how current price interacts with prior structural ranges. It does not issue trade signals or forecasts.

Key Features
• Tracks higher-timeframe reference bars across the session.
• Plots draw lines at the opposite extreme once a break occurs.
• Displays dynamic CH and optional EOD probabilities derived from embedded historical statistics.
• Tested lines change style once price interacts; expired levels are automatically removed.
• Fully customizable palette, text size, and visibility options.




Signal Area Context
HIPA includes an optional Signal Area overlay that blends IRL probabilities with higher-timeframe (HTF) structure.
You can reference candle highs/lows or pivots from selected HTF intervals and display a subtle gradient between these external liquidity points and active IRL zones.
The shaded area is intended to help visualize where intraday behavior aligns with multi-timeframe liquidity zones — not to produce entries or exits.
Traders may use it to study how price develops around these confluence regions.



Methodology (transparency)
HIPA uses embedded statistical references derived from long-term historical market behavior to estimate revisit probabilities conditioned by time-of-day and break direction.
These references are stored directly within the script for deterministic plotting — no external data is fetched or required.
Session data is internally organized into consistent time segments to reflect how revisit tendencies vary through the day.

HIPA is descriptive: it visualizes empirically observed behavior, not predictive outcomes.

How to Use
- Apply HIPA to any intraday chart.
- Observe when price breaks a higher-timeframe candle’s high or low — a draw line appears at the opposite extreme with CH/EOD labels.
- Optionally enable the Signal Area to visualize overlap between HTF liquidity and current IRL zones.
- Use HIPA as structural and statistical context only; combine with your own framework for decision-making.
- Treat draw lines and gradients as reference areas rather than precise trade levels.

Notes
• Historical behavior can evolve under different market conditions.
• CH/EOD probabilities adjust with session time; interpret contextually.
• Rendering many lines simultaneously may affect performance — enable pruning if needed.
• Works on any symbol or timeframe supported by TradingView.
