What is a Fair Value Gap (FVG)?
Updated June 2026 · 8 min read
A Fair Value Gap (FVG) — also called an imbalance— is one of the most widely used concepts in ICT trading and Smart Money Concepts. It refers to a zone on the chart where price moved so quickly and impulsively that an imbalance was created: one side of the market (buyers or sellers) completely dominated, meaning price was not traded "efficiently."
The result? The market tends to return to that zone to correct the imbalance. And that is exactly what SMC and ICT traders play for: they wait for the return to the FVG and use it as an entry zone.
FVG in one sentence
A Fair Value Gap is a zone between three consecutive candles where the wick of candle 1 and the wick of candle 3 do not overlap, indicating a supply-demand imbalance that the market will likely retest later.
How do you identify a Fair Value Gap?
An FVG always consists of three candles. The definition:
Bullish FVG (upward imbalance)
The high of candle 1 is lower than the low of candle 3. There is a gap between the upper wick of candle 1 and the lower wick of candle 3. Candle 2 is the impulse candle — a large bullish candle that moved through that gap.
Bearish FVG (downward imbalance)
The low of candle 1 is higher than the high of candle 3. The impulse candle (candle 2) is a large bearish candle. There is a gap above candle 3 and below candle 1 that was not traded.
The FVG zone is the area between the wick of candle 1 and the wick of candle 3. That is the zone the market is most likely to return to.
Why does price return to an FVG?
The logic behind FVGs is based on the concept of market efficiency. When price moves too quickly, not all orders at all price levels get filled. A "gap" remains in the market where supply and demand were not in balance. Large institutional players have an interest in this: they want to add to their positions at the most favorable prices, and the FVG zone is exactly where that can happen.
In practice, the FVG behaves like a magnet. After a strong impulse, the market often returns to the FVG — sometimes touching the zone precisely, sometimes filling it halfway, sometimes completely. In ICT terminology this is called filling the imbalance.
How do you use an FVG as an entry?
An FVG alone is not a setup. It is a zone — not a signal. You use the FVG in combination with the broader context of Smart Money Concepts:
Step-by-step FVG entry
HTF bias: Determine on the 4H or daily chart whether the trend is bullish or bearish. The FVG must align with the HTF direction.
Liquidity sweep: Wait for a sweep of a clear liquidity level (equal highs/lows, previous swing). This shows that smart money is active.
CHoCH + displacement: After the sweep, expect a Change of Character and an impulsive move in the new direction. The FVG forms within that displacement.
Entry in the FVG: Wait until price returns into the FVG. Many traders place a limit order at 50% of the FVG (the midpoint), or at the start of the zone.
Stop loss: Just below the FVG (bullish setup) or just above (bearish setup). If the FVG is completely filled without respect, the setup is invalid.
Target: The next liquidity pool, a previous high/low, or a higher timeframe FVG above/below the current position.
Types of FVGs you need to know
Consequent Delivery FVG
This is an FVG that forms in the direction of the HTF trend, after a CHoCH. This is the strongest variant — the market clearly signals institutional interest in that direction.
Rejection FVG
An FVG that the market touches but does not fully fill, after which price still moves in the expected direction. This is a strong signal that the zone is being respected.
Inverted FVG
When an FVG is completely filled and price breaks through it, the zone can flip from support to resistance (or vice versa). This is called an inverted FVG and can serve as a new entry zone in the opposite direction.
Propulsion FVG
An FVG that forms between two impulsive moves in the same direction. Also seen as a "re-entry" zone when the first move has already reached part of the target.
FVG vs. Order Block: what is the difference?
FVGs and order blocks are often used together but are not the same:
| Aspect | Fair Value Gap | Order Block |
|---|---|---|
| Definition | Gap between 3 candles | Last candle before the impulse |
| Logic | Market imbalance | Institutional order zone |
| Entry type | Limit order in the gap | Limit order on the OB candle |
| Precision | High — tight zone | Slightly broader |
In practice, FVG and OB often overlap. The combination of both — an order block that also has an FVG present — is considered a particularly strong confluence zone.
Common mistakes in FVG trading
Mistake 1: Trading every FVG
Not every FVG is an entry. Without HTF bias, a liquidity sweep, and a CHoCH, an FVG is just a random gap on the chart. Context is everything.
Mistake 2: Entering too early
The FVG zone can be wide. Wait until price actually reaches the zone before opening a position. Anticipating the FVG without confirmation leads to poor entries.
Mistake 3: Placing the stop loss too far
One of the strengths of FVG entries is precision. If you place your stop far away "for safety," you lose the favorable risk-reward advantage that FVGs offer.
Mistake 4: Trading at the wrong times
FVGs formed outside the London or New York killzone are less reliable. Institutional liquidity is unevenly distributed throughout the day.
Tracking FVGs in your trading journal
If you want to trade FVGs consistently, you need data. Which FVGs get filled and which do not? On which timeframe do they work best for you? How long on average before price returns? Are there combinations with order blocks that perform better?
You do not answer these questions by staring at charts — you answer them by documenting every trade and analyzing patterns over time.

A Fair Value Gap is one of the most reliable entry concepts within ICT and SMC — but only when used in the right context. FVGs that align with a clear HTF bias, are preceded by a liquidity sweep and a CHoCH, and occur within a killzone offer an excellent combination of precision and risk-reward.
Track which FVGs you trade, note the context, and analyze your results. That is the difference between a trader who "trades FVGs" and a trader who understands why certain FVGs work and others do not.
Frequently asked questions about Fair Value Gaps
Are all FVGs always filled?
No. The market has a strong tendency to fill FVGs, but it is not guaranteed. FVGs that form in the direction of a strong institutional trend are sometimes filled much later, or not at all. Context is everything — an FVG aligned with the HTF trend is more reliable than a counter-trend FVG.
On which timeframe are FVGs most reliable?
FVGs on higher timeframes (4H, 1H) are more stable and more respected. For entries, use the 15m or 5m to time the return to the zone precisely. Never rely on only the 1m or 3m — those contain too much noise.
What do you do if an FVG is completely filled and price breaks through?
Then the setup is invalid and you close the trade. An FVG that is completely filled with price closing outside the zone shows there is no longer institutional interest at that level. Accept the loss and wait for the next setup.
What is the difference between an FVG and a regular gap?
A regular gap (such as a weekend gap) is a jump in price between two sessions. An FVG is a specific 3-candle formation where price trades continuously but moves so quickly that an imbalance zone is created. FVGs can occur on any timeframe; regular gaps only occur at session transitions.
Should I always wait for price to return to the FVG?
In the classic ICT/SMC approach, yes — you wait for the pullback into the FVG for the entry. Some traders use an "aggressive entry" on the CHoCH candle itself, but this has a smaller risk-reward. For beginners, waiting for the pullback into the FVG is the smarter approach.
