The ICT Fair Value Gap (FVG) is one of the highest-probability price action setups in the order flow / Smart Money toolkit. It describes a 3-candle imbalance that institutions create when they move price aggressively in one direction, and the unfilled price zone they always come back to. When you learn to read FVGs in context — at HTF levels, with confluence, and with proper mitigation — you trade the same inefficiencies the big players are rebalancing.
*Hit-rate on HTF FVGs that align with the higher-timeframe trend. LTF FVGs in chop fail more often.
What Is a Fair Value Gap?
A Fair Value Gap (FVG), sometimes called a "value gap" or simply an "inefficiency," is a 3-candle price action pattern where the wicks of the first and third candles do not overlap. The space between them is the FVG — a price range where no trading activity occurred during the original move.
It forms when one side of the market (buyers or sellers) gets aggressively aggressive: they push price through resting orders so fast that there's a "void" left behind. Smart money, which operates on the principle that price must rebalance inefficiencies, will usually return to that void before continuing the move.
You'll sometimes see FVGs referred to in the literature as "inefficiencies" or "imbalances" — they are the same concept. ICT's contribution was to formalize the structure (3 candles, wicks not overlapping) and to build a methodology around when and how price rebalances them.
The 3-Candle Mechanics (Precise)
Defining an FVG properly is mechanical. There is no subjectivity in identifying the zone — just measurements.
Bullish FVG — gap between candle 1's high and candle 3's low. Yellow line = Consequent Encroachment (50%).
Consequent Encroachment (CE) — The 50% Level
Inside every FVG is a single line that matters more than the rest: the Consequent Encroachment (CE). It is the 50% midpoint of the FVG zone — the precise price where the inefficiency is most "unfair" and where the highest-probability re-entry tends to occur.
The logic: the top of a bullish FVG is where sellers were last in control, and the bottom is where buyers took over. The midpoint is the equilibrium — the line at which neither side has an edge. When price returns to an FVG and taps the CE, it often produces a sharp reaction because the unfilled orders on both sides converge at that level.
Why FVGs Work — The Institutional Logic
FVGs are not magical. They're a direct, mechanical consequence of aggressive institutional execution. When a large player needs to fill a multi-million-dollar order, they don't do it at one price — they push through the order book, leaving a "void" of unfilled prices behind. The market's natural rebalancing behavior then pulls price back to fill that void.
Three forces drive FVG rebalancing:
- Algorithmic rebalancing. Most execution algos and many HFTs are designed to fade inefficiencies. They detect the gap and target it for mean reversion.
- Unfilled institutional orders. The orders that were skipped during the original displacement are still resting at those prices. When price returns, they get filled.
- Visible structure. When many traders see the same FVG on the same chart, they place the same orders there. Self-fulfilling liquidity pool.
This is also why the underlying order flow / auction theory behind FVGs is so important — without understanding displacement, you can't tell a real FVG from noise.
Trading a Bullish FVG (Long)
Trading a Bearish FVG (Short)
Mirror image. HTF downtrend → bearish FVG forms in premium → price returns to CE → bearish mitigation candle prints → entry on close → target opposing HTF demand or HTF FVG.
Longs happen at bullish FVGs that formed in a discount zone (below 50% of range). If the FVG is in premium, the trade is lower quality.
Shorts happen at bearish FVGs that formed in a premium zone (above 50% of range). Premium shorts are the highest-quality ICT setups.

Stop = FVG low · Target = HTF supply / opposing FVG.
Inverse Fair Value Gap
An Inverse FVG forms when an existing FVG is broken by price, flipping its polarity. The previously bullish FVG becomes a bearish supply zone (or vice versa). Inverse FVGs are some of the highest-probability setups in ICT methodology because they represent a confirmed structural shift combined with an untested inefficiency.
Inverse FVGs are particularly powerful when they form at the start of a new leg, after a liquidity sweep, or as a confirmation of a mitigation candle at a major HTF level.
FVG Chains & FVG-to-FVG Trading
In trending markets, FVGs form a sequence — each displacement creates a new FVG, and price often targets the next FVG in the chain as it advances. The "FVG-to-FVG" approach uses this systematically: enter on the mitigation of one FVG, target the next FVG in the direction of the trend.
Three useful rules for FVG chains:
- Same-direction chain: Bullish FVGs in a bullish trend target the next untested bullish FVG. Each mitigation becomes a stepping stone.
- Opposing FVG as target: A long often targets the next bearish FVG above — the inefficiency on the other side of the move.
- HTF FVG is the boss: LTF FVG chains respect the most recent HTF FVG. If you're in an LTF long and price is approaching an HTF bearish FVG, that HTF level will likely reject the move.
FVG Confluences — Stacking the Probabilities
An FVG alone is interesting. An FVG that overlaps with three other confluences is tradeable. The most powerful confluences:
HTF vs. LTF FVGs
Not all FVGs are equal. A Daily FVG represents a much larger institutional footprint than a 5-minute FVG. The hierarchy:
- Weekly / Daily FVGs: Institutional. Highest hit-rate, biggest targets, slowest to mitigate.
- 4H / 1H FVGs: Strong. Common swing-trading timeframe, very reliable with HTF context.
- 15M / 5M FVGs: Retail. Many are noise. Tradeable only when they align with HTF FVGs and have clear mitigation.
- 1M FVGs: Mostly noise. Skip.
The general principle: the higher the timeframe of the FVG, the more significant the inefficiency. Most professional FVG traders focus on 1H+ FVGs and treat sub-15M FVGs as execution refinements, not signal sources.
FVGs Across Markets
FVGs work on any liquid instrument that produces structural price action. Common markets and notes:
Cleanest FVGs. 1H and 4H timeframes work exceptionally well. London and NY opens produce the most reliable setups.
15M and 1H FVGs align well with cash-session liquidity. Pre-market and overnight FVGs often get filled at the open.
24/7 market. 4H and Daily FVGs are the most reliable. Weekend gaps create high-quality FVGs that often get filled on Monday.
Pre-market and opening drive produce large FVGs. Tradeable 15M and 1H setups, but respect earnings and macro events as FVG invalidators.
Common FVG Mistakes
Every market has dozens of FVGs. Trade only the ones with HTF context, mitigation, and clean CE taps.
Don't predict that price will tap a far-away FVG. Wait for the actual mitigation candle close.
The CE (50%) is the optimal entry. The extremes are stop and limit levels, not entries.
Stop goes just beyond the FVG low/high. 1–2× ATR buffer. Anything wider and your R:R breaks.
An FVG in the middle of a range is noise. An FVG at HTF discount/premium is a trade.
Not every FVG mitigates. Some get skipped. If price blows through the FVG without a clean mitigation candle, the setup is invalidated.

Real Trade Examples
Six annotated examples across forex, indices, and crypto. Each one is a real-world application of the FVG framework — the way the setup actually appears in a live market.
Setup: Daily uptrend, 4H pullback into 1H bullish FVG in a discount zone. Price tapped the CE at 1.0825 on the NY open. A wide-range bullish mitigation candle printed inside the FVG and closed in the upper third. Entered on close. Target hit at the 4H supply zone / opposing 4H FVG.
Confluences: HTF uptrend · discount zone · NY open · mitigation candle · 4H supply target. HTF FVG alignment: Daily FVG was unmitigated and acted as the directional anchor.
Setup: 4H downtrend, NY open swept the prior swing high (liquidity grab), then dropped hard leaving a 15M bearish FVG. Price pulled back up into the FVG's CE on the 15M. A bearish mitigation candle closed in the lower third. Entered short on close.
Confluences: HTF downtrend · liquidity sweep at NY open · premium zone · 15M FVG in discount of impulse · 4H order block overhead. Setup fired in 2 hours and ran straight to the opposing 4H FVG.
Setup: Weekly uptrend on BTC, Daily pullback into a 4H bullish FVG sitting on a major weekly demand zone. Price tapped the CE on a Sunday evening (pre-Asia). A wide-range bullish mitigation candle printed at NY open and ran for over 24 hours.
Confluences: Weekly trend · Daily discount · weekly demand zone · 4H FVG with clean CE · HTF order block alignment · clean mitigation candle. The setup ran straight to the opposing 4H bearish FVG above.
Setup: 1H downtrend, but the FVG formed in the middle of the range — not at a clear HTF supply zone. Entry was taken during the Asian session on a bearish mitigation candle, but price reversed on the London open and ran straight through the FVG high.
What went wrong: Asian session entry, no HTF supply confluence, no liquidity sweep confirmation, FVG sitting in equilibrium (not premium). Lesson: Even a valid FVG mitigation fails when context is missing. The setup had the right shape but the wrong location and timing. Loss was contained to 1R.
Setup: Original 15M bullish FVG was created on a Tuesday morning rally, then price reversed and broke below the FVG low on the NY open (a clear liquidity sweep of the equal lows). The FVG flipped polarity. On the retest, a bullish mitigation candle printed at the CE of the inverse FVG.
Confluences: Liquidity sweep · inverse FVG flip · NY open · mitigation candle at CE · HTF discount · opposing 1H FVG target above. Inverse FVGs combined with liquidity sweeps are some of the highest-probability ICT setups.
Setup: Daily uptrend on gold. 4H pulled back into a 1H bullish FVG at a major demand zone. The CE sat right on the Daily 50% equilibrium. Entered on the close of a 1H mitigation candle at the London open. Target was the next 4H bearish FVG (FVG 2 in the chain).
FVG chain: Once FVG 1 mitigated, price ran to FVG 2. After FVG 2 was pierced, price continued to FVG 3 — the daily opposing FVG that capped the move. Confluences: Daily uptrend · 4H discount · Daily equilibrium · London open · clean mitigation candle · 3-step FVG chain target. This is how FVG-to-FVG trading works in practice.
