Based on Inner Circle Trader (ICT) algorithmic price action theory, this indicator specifically targets the First Presented Fair Value Gap (F-FVG) that forms immediately after the start of a Time-Range or trading Session (such as the New York AM Open).
This First Presented FVG represents a significant imbalance in price delivery. Identifying the initial displacement gap can play a crucial role in framing future price movements, acting as a primary draw on liquidity or a high-probability point of support/resistance for the session.
