FVG with Probabilities
Apr 24, 2026

The FVG with Probabilities indicator is a comprehensive toolkit designed to quantify the likelihood of a Fair Value Gap (FVG) holding or failing using a complex scoring model. It provides traders with objective data to distinguish between high-confluence setups and market noise, making it particularly useful for institutional-grade scalp trading and lower-timeframe analysis.
Usage
The indicator automatically detects Fair Value Gaps and assigns them a probability score based on multiple confluence factors. Traders can use these scores to filter setups:
- High Quality (H): Scores above the high cutoff (default >65%) indicate high-confluence zones where price is likely to react.
- Medium Quality (M): Standard setups with moderate confluence.
- Inversion FVGs (IFVG): When a gap is violated by a displacement candle on the opposite side, the indicator flips the zone (e.g., bullish FVG becomes bearish resistance).
Traders should look for "A+" setups which occur when price retests a high-scoring FVG within a designated Killzone, ideally supported by trend alignment (EMAs) and volume confirmation.
Details
The core of the script is a weighted scoring model that calculates probabilities between 4% and 85%. The model evaluates eight key factors:
- P/D Alignment: Checks if longs are in discount or shorts are in premium relative to swing points.
- Market Structure: Rewards alignment with recent Breaks of Structure (BOS).
- Displacement: Requires specific body-to-range ratios and ATR-relative size to ensure institutional energy.
- Consequent Encroachment (CE): Monitors the 50% midpoint of the gap as a primary reaction level.
- Regime Filtering: Adjusts scores based on volatility (ATR ratio) and institutional volume (RVOL).
Settings
The settings are organized into several functional groups:
- FVG Detection: Adjust sensitivity via the Min FVG Size (ATR multiplier) and toggle CE visibility.
- Displacement Filter: Define the strictness of displacement via body-to-range and body-to-ATR ratios.
- IFVG Rules: Configure how failed gaps are converted into inversion zones, including required displacement for the "flip."
- Quality Score: Set the thresholds for High and Medium probability cutoffs and configure EMA lengths for trend bias.
- Signal Engine: Toggle entry signals based on minimum scores, specific modes (Trend/Reversal), and Killzone requirements.
- Killzones: Define custom sessions for London, NY AM, and NY PM trading hours.
- Time-of-Day Filter: Skip volatile opens, low-volume lunch periods, or end-of-day noise.
FAQ
- How do I interpret the probability score on a gap? The score represents the confluence of factors like trend, volume, and structure. Higher percentages suggest a greater probability of the level acting as support or resistance.
- What is an Inversion FVG (IFVG)? An IFVG occurs when a regular FVG is closed through with displacement. The zone then "inverts," changing from support to resistance (or vice versa).
