Fair Value Gap Explained: What It Is and How Price Actually Reacts to It

What a fair value gap actually is

A fair value gap, often shortened to FVG, is a three-candle pattern where the wick of the first candle and the wick of the third candle don't overlap, leaving a visible gap between them. It forms when the middle candle moves fast and far enough in one direction that price skips over a range without trading through it in both directions, leaving what's sometimes called an imbalance, a stretch of price with far more orders on one side than the other.

Why these gaps actually form

Normal price action tends to trade back and forth through a range as buyers and sellers exchange at multiple prices before moving on. A fair value gap forms when that two-way exchange doesn't happen, usually during a fast, one-sided move driven by a news release, a large order hitting the market, or a sudden shift in sentiment. The result is a price zone that was passed through, but not really "traded," in the normal back-and-forth sense.

Bullish vs bearish fair value gaps

A bullish fair value gap forms during a sharp move higher, leaving an untraded zone below current price. A bearish fair value gap forms during a sharp move lower, leaving an untraded zone above current price. Both are read the same way: as a zone price left behind without fully processing, which is why some traders expect it to matter again later.

The "rebalancing" idea, and why it isn't guaranteed

The common theory behind fair value gaps is that price tends to return and "rebalance" these imbalanced zones before continuing in its original direction, since the two-sided trading that never happened the first time still needs to happen eventually. This tendency shows up often enough to be worth watching, but it isn't a rule price is required to follow. A strong enough trend can leave several fair value gaps completely unfilled for a long stretch, so treating a gap as a guaranteed magnet is a common overstatement of what the concept actually predicts.

How traders actually use fair value gaps

Most practical use of fair value gaps falls into one of two roles: as a target, where a trade already in profit is expected to reach toward an unfilled gap before reversing, or as an entry zone, where a pullback into a gap is treated as a potential area for price to react, similar to how an order block is used. Neither use treats the gap as a signal on its own. Like every concept inside smart money concepts, it works best combined with confirmation from structure, not read in isolation.
