Fair Value Gaps (FVG) and Imbalances: Testing Mitigation Rates Across Pairs

• A Fair Value Gap (FVG) represents an inefficiency in price delivery where aggressive market orders consume all opposing resting orders, creating a price imbalance. • An FVG is anatomically defined across 3 consecutive candles: the space between Candle 1's high and Candle 3's low (Bullish FVG). • Price acts like a vacuum: algorithmic pricing engines seek to deliver balanced two-sided auction pricing by revisiting and mitigating these gaps. • Mitigation rates differ significantly by market: Forex pairs exhibit an 82% mitigation rate, whereas volatile Crypto assets frequently leave breakaway gaps unfilled during aggressive expansions. • The 50% Consequent Encroachment (CE) of an FVG provides the ultimate institutional entry level with minimal drawdown.

In an efficient two-sided market auction, every tick upward has matching buy and sell transactions, resulting in overlapping candlestick wicks. However, when institutional algorithmic capital unleashes aggressive market buy orders, price spikes violently in a single direction. Anatomy of a Bullish Fair Value Gap (FVG): • Candle 1: Preceding baseline candle. • Candle 2: Aggressive, long-bodied green expansion candle. • Candle 3: Following continuation candle. If Candle 1's high does not overlap with Candle 3's low, an unmitigated imbalance exists between Candle 1's high and Candle 3's low. In this price pocket, only buy orders were executed; sellers were completely absent. Because central bank and liquidity provider algorithms prioritize balanced price delivery, price will frequently retrace back down into this gap to re-auction contracts to buyers who missed the initial move. This process is called "Mitigation." Key Sub-Levels within an FVG: 1. Premium/Discount Boundary: The open edge of the gap. 2. Consequent Encroachment (CE): The exact 50% midpoint of the imbalance. In high-probability institutional setups, price will touch the CE and immediately reject with strong displacement wicks.

Step-by-Step FVG Backtesting Protocol: 1. Scan for 3-Candle Imbalances: - On the 15m or 5m chart, step forward until a large-bodied candle prints. - Verify that Candle 1's wick and Candle 3's wick do NOT overlap. 2. Draw the FVG Box: - Use the rectangle drawing tool to shade the zone from Candle 1 High to Candle 3 Low. - Use the Fibonacci Retracement tool to mark the 0.50 Consequent Encroachment (CE) line. 3. Step Forward Candle-by-Candle: - Monitor price re-entry into the FVG: - Level 1: Does price tag the open boundary? - Level 2: Does price tag the 50% CE level? - Level 3: Does price completely fill the gap (full closure)? - Level 4: Does a candle body close outside the opposite side of the gap (gap invalidation)? 4. Record the Mitigation Performance: - Log whether an entry at the 50% CE produced a winning reaction. - Record the time duration (how many candles elapsed before mitigation occurred).

Common Mistakes: • Trading Every Micro FVG: Marking 1-minute FVGs in the middle of a consolidating range. Only trade FVGs that formed during a genuine Market Structure Shift (MSS). • Expecting 100% Fill: Many retail traders wait for a 100% complete fill, missing high-probability trades that bounce cleanly off the 50% Consequent Encroachment. Institutional Best Practices: • Inversion Fair Value Gaps (IFVG): If an FVG fails and price aggressively closes through it, immediately flip it into an Inversion FVG. The former support gap now acts as institutional resistance on the retest. • Pair-Specific Calibration: EUR/USD and GBP/USD respect FVGs with surgical precision; volatile altcoins require slightly wider stops to accommodate slippage.

Primary Metric to Track: Consequent Encroachment Respect Rate (CERR) $$\text{CERR (\%)} = \frac{\text{FVGs Where Candle Bodies Respected 50\% CE}}{\text{Total Mitigated FVGs}} \times 100$$ Target: Look for setups with $>75\%$ CERR. If an asset class consistently fails to respect the 50% midpoint, switch to trading Breakers or Order Block wick extremes.
