Fair Value Gap (FVG): institutional meaning
By Ken Chigbo, Founder, KenMacro. Published 2026-05-14.
Definitive answer
A fair value gap, or FVG, is a three-candle imbalance where the wick of candle one and the wick of candle three fail to overlap because the middle candle delivered price too quickly in one direction. The unfilled zone between those two wicks marks inefficient, one-sided trade. Price often revisits part of that zone before resuming the prior move, though revisits are probabilistic, not guaranteed.
Mechanically, the gap appears when aggressive flow on the middle candle absorbs resting liquidity faster than passive orders can replenish the book. A bullish FVG sits inside an up-move, with the prior high below the next low. A bearish FVG sits inside a down-move, with the prior low above the next high. The unoverlapped range is the imbalance itself, and algorithms flag it as a candidate area for later mean reversion.
Order flow desks, ICT-style discretionary traders, and quant teams modelling auction inefficiency all reference FVGs. The pattern matters most around scheduled catalysts such as Fed, ECB, and BoE releases, US cash-equity opens, and London fix windows, where one-sided delivery is structurally more frequent. Lower timeframe FVGs print constantly and carry little information; higher timeframe imbalances on the 1H, 4H, and daily are the ones institutional flow tends to respect.
The common misconception is treating every FVG as a level that must fill. Many do not. An imbalance is a probabilistic magnet, not a guarantee, and price can run further before any revisit, or never return at all. The desk pairs FVGs with market structure, liquidity pools, and session context rather than trading them in isolation, an approach covered in detail in ICT concepts decoded: order blocks, FVG and liquidity at https://kenmacro.com/ict-concepts-decoded-order-blocks-fvg-liquidity/.

Frequently asked
Does a fair value gap always get filled?
No. A fair value gap is a probabilistic draw on price, not a mandatory target. Many imbalances are partially filled, others are revisited weeks later, and some are never touched again. Higher timeframe FVGs are filled more reliably than lower timeframe ones, but no FVG carries a guarantee.
What is the difference between a fair value gap and an order block?
A fair value gap is the price range left unfilled between candle one and candle three wicks. An order block is the last opposing candle before a strong displacement move. The two concepts overlap because displacement that creates the order block also tends to leave the FVG immediately after it.
Which timeframe is best for spotting fair value gaps?
Institutional desks prioritise 1H, 4H, and daily imbalances because they reflect meaningful one-sided delivery. Sub-15-minute FVGs print constantly during normal auction noise and carry far less informational value. Higher timeframe gaps aligned with market structure shifts and liquidity pools produce the most consistent reactions.
