Fair Value Gap (FVG), Explained

A fair value gap, or FVG, is a small "hole" left on a chart when price moves so quickly that it skips over a range of prices. It is also called an imbalance or an inefficiency. The framework around it assumes that markets dislike leaving prices unvisited, so price often drifts back later to "fill" the gap before continuing. It is a tidy idea, and like every concept in this family, it describes a tendency rather than a promise.

The reason it gets so much attention is that an FVG is mechanical to spot. Once you learn the three-candle shape, you cannot unsee it.

The three-candle pattern

A fair value gap is defined by three candles in a row. Look at the first candle and the third candle. If there is a gap between the high of the first and the low of the third (in an up-move), the space in between — which the big middle candle blew through — is the fair value gap. In a down-move it is the mirror: a gap between the low of the first candle and the high of the third.

In short: the middle candle is so strong that the wicks of its neighbors do not overlap. That untouched space is the imbalance. If candlestick anatomy is new to you, read candlesticks, explained first, because the whole pattern is about wicks and bodies.

Why a gap forms in the first place

The intuition is genuinely useful. A normal, healthy move has buyers and sellers trading at every price along the way — wicks overlap, auctions happen at each level. An FVG forms when one side is so dominant that price rockets through a zone without any real two-sided trading. That can happen on news, on a stop cascade, or when large players push hard.

The framework reads that as unfinished business. Because so little trading happened in that pocket, the thinking goes, the market may come back to trade it "fairly" before moving on. This is closely tied to liquidity, because the same fast moves that leave gaps often happen right after a liquidity grab.

How traders actually use it

Most people use an FVG as a zone of interest, not a signal by itself. A common approach is to wait for price to return to the gap and then look for confirmation in the direction of the larger trend — for example, an FVG that lines up with an order block or that forms right after a break of structure. The gap gives a location; the structure gives a reason; risk management decides whether to act at all.

The whole idea sits inside the broader Smart Money Concepts toolkit, where the FVG is one of the most popular tools because it is so easy to mark objectively.

The part the hype skips

Gaps do not always fill. Some sit open for a very long time, or never close. Price can also poke into a gap and reverse before reaching the middle, or fill it and keep right on going as if it were never there. "FVGs always get filled" is a myth; plenty stay open. Treating an unfilled gap as a sure thing is how a clean-looking idea turns into an expensive habit.

So keep the FVG in its proper place: a precise way to mark where price moved inefficiently and might react. Pair it with structure and, above all, with defined risk. Read risk-first trading, practice spotting gaps on a clean chart, and when you want reps under guidance, the School and a challenge are built for exactly that. The gap tells you where to look. It never tells you that you cannot be wrong.
