Fair Value Gaps, Explained for Futures Traders
A fair value gap is a price zone left behind when the market moves so fast it skips over a level, and traders watch to see if price comes back to that zone later. You spot it using three candles in a row. The middle candle makes a big, one-sided move, and the gap is the untraded space between the first candle's wick and the third candle's wick that the middle candle jumped straight past. On NQ and ES these gaps show up all the time, because index futures move quickly. The idea is that the fast move happened without much two-way trading, so price may return to fill that empty zone before continuing. Treat a fair value gap as context for where price might react, not a promise that it will.
A fair value gap marks an imbalance left by a fast move. How NQ and ES traders use these zones as context for where price may react, not as a guaranteed fill.
Key points
- A fair value gap needs three candles: the middle one makes a fast, one-sided move, and the gap is the untraded space it leaves between the outer two candles' wicks.
- The gap marks an imbalance, meaning buyers or sellers were so aggressive that price jumped a level instead of trading through it slowly.
- A bullish gap sits below current price and a bearish gap sits above, and traders watch those zones as possible reaction areas if price comes back.
- Not every gap gets filled, so a fair value gap is context for where price might pause or turn, never a guaranteed target.
- On NQ and ES these gaps form constantly during fast sessions like the open, so most traders only pay attention to the larger, cleaner ones near key levels.
- If you want your charts to flag these gaps automatically, you can describe the three-candle rule in plain words in AlgoAgent and generate a TradingView indicator for it.
Frequently asked questions
What is a fair value gap in simple terms?
A fair value gap is a spot on the chart where price moved so fast it left a small empty zone behind. It shows up across three candles, where the middle candle jumps past a level instead of trading through it slowly. Traders watch that zone to see if price comes back to it later.
How do you identify a fair value gap on a chart?
Look at three candles in a row. For a bullish gap, check whether the high of the first candle sits below the low of the third candle, with the middle candle's big move creating the space in between. That untouched space is the fair value gap. A bearish gap is the same idea flipped, with the first candle's low above the third candle's high.
Do fair value gaps always get filled?
No. Plenty of gaps get filled, but plenty do not, especially in a strong trend where price keeps running. That is why a fair value gap is better used as context, meaning a zone where price might react, rather than a target you count on. Pairing it with other levels usually helps more than trading the gap on its own.
What is the difference between a fair value gap and an order block?
They are related but not the same. An order block is usually the last candle before a strong move, seen as an area where large orders sat. A fair value gap is the empty space that the fast move left behind. Many traders look for both in the same spot, since a gap sitting next to an order block can mark a zone worth watching.
How can I mark fair value gaps on my futures charts?
Most charting platforms do not highlight them by default, so traders either mark them by hand or use an indicator that scans for the three-candle pattern. If you would rather not code it yourself, you can describe the rule in AlgoAgent and it will generate a TradingView indicator that flags the gaps for you. That keeps the zones marked automatically so you can focus on how price reacts. These are context tools for study, not trade recommendations.
