A Fair Value Gap (FVG) is a concept used in technical analysis, particularly in smart money trading strategies. It refers to an imbalance in price action where the market moves so quickly that one side of the trade (buyers or sellers) is left unfilled. This often happens when there's a large move caused by strong momentum, leaving a "gap" between candles. These gaps can act like magnets — price often returns to these areas to "fill" the imbalance before continuing in its original direction. Traders watch Fair Value Gaps as potential entry or exit points, expecting price to revisit and react at those levels.
