Fair Value Gaps (FVGs) & Inversion Mechanics: Trading Algorithmic Imbalances
In classical technical analysis, gaps are often treated as rare weekend anomalies or simple exhaustion signs. In institutional order flow, however, Fair Value Gaps (FVGs) are the primary fingerprint left behind when central bank algorithms reprice an asset with explosive efficiency.
An FVG represents a single-sided inefficiency where only buyers (or only sellers) were present during a rapid price expansion. Understanding how algorithms target, rebalance, and invert these gaps gives you a profound edge when entering trades during live market sessions.
The Anatomy of a Fair Value Gap
A valid Fair Value Gap is a three-candle sequence where a sharp displacement candle leaves an unfilled void between the wicks of the surrounding candles.
The Algorithmic Mechanics:
Candle 1: Forms a swing high wick.
Candle 2 (Displacement): Explodes upward with high institutional volume, breaking structure.
Candle 3: Forms a low wick that fails to reach down to the high wick of Candle 1.
The empty space between Candle 1's high and Candle 3's low is the Fair Value Gap. Because price moved too fast for counter-orders to be matched, the algorithm views this price region as "inefficient." It will eventually drag price back into this gap to balance the orders.
Key Algorithmic Levels Within an FVG
When price returns to rebalance a Fair Value Gap, it doesn't move randomly inside the void. Algorithms react to two precise price boundaries:
Consequent Encroachment (CE): The exact 50% midpoint of the Fair Value Gap. This is the ultimate algorithmic reaction point. If price touches the 50% CE level and respects it, the setup holds maximum probability.
Full Rebalance: If price completely closes through the gap, it has fully delivered liquidity. However, if a candle body closes beyond the far boundary of the FVG,...
