Fair Value Gaps: Trading the Imbalances Institutions Leave Behind
A Fair Value Gap is a three-candle pattern that marks a zone where price moved so aggressively that it left an imbalance — an area where buyers and sellers never had a chance to trade. Price has a strong tendency to return and fill these gaps.
Markets are constantly seeking balance — a state where both buyers and sellers are satisfied with the current price. When an institution places a massive order, price can move so rapidly that it skips past a range of prices without any meaningful two-way trading occurring. That skipped zone is called a Fair Value Gap. It represents an imbalance, and the market frequently returns to resolve it.
Bullish FVG: gap between Candle 1's high and Candle 3's low — price tends to return and fill this zone. Bearish FVG is the mirror.
How to Identify a Fair Value Gap
An FVG is defined by three consecutive candles. The structure is simple:
- Bullish FVG: The high of candle 1 does not reach the low of candle 3. The gap between them — the zone candle 2 moved through without overlap — is the FVG.
- Bearish FVG: The low of candle 1 does not reach the high of candle 3. The gap between them is the FVG.
The Simple Test
Look at candle 1 and candle 3 only. In a bullish FVG: does candle 1's high touch candle 3's low? If not — there is a gap between them. That gap is the FVG. The bigger the gap, the stronger the imbalance.
Bullish FVG Example
Candle 1 closes at $100 with a high of $101. Candle 2 is a strong bullish candle moving from $100 to $108. Candle 3 opens at $108 with a low of $103. The gap between $101 (candle 1 high) and $103 (candle 3 low) = the FVG zone. Price moved through $101–$103 so aggressively that no balanced trading happened there.
Why Price Returns to Fill FVGs
In the SMC framework, institutions that caused the impulsive move often have remaining orders to fill — orders they could not fully execute during the rapid move. When price retraces to the FVG zone, it gives them the opportunity to complete their position at the prices they wanted. This institutional demand (or supply) in the FVG is what gives the level its holding power.
From a pure market mechanics perspective, the FVG is also a zone of price discovery — the market revisiting prices it passed through too quickly to establish fair two-way trading.
Trading the FVG: Entry Strategy
- Identify the FVG on your analysis timeframe (1H or 4H gives the clearest signals).
- Wait for price to retrace back into the FVG zone — not just approach it, but actually enter the gap.
- Look for a rejection candle or confirmation signal inside the FVG before entering.
- Enter in the direction of the original impulsive move that created the FVG.
- Place your stop-loss below the FVG (for bullish) or above it (for bearish) with a small buffer.
- Target the next significant high (bullish) or low (bearish), or the next opposing FVG.
The 50% Level of the FVG Is the Highest Probability Entry
Not all of the FVG needs to fill for it to act as support or resistance. The midpoint of the FVG (50% of the gap's height) is often where the strongest reaction occurs. Many traders use this as their primary entry level rather than waiting for a full fill.
Bullish vs Bearish FVG Behaviour
| Bullish FVG | Bearish FVG | |
|---|---|---|
| Forms during | A rapid upward move (3 bullish candles) | A rapid downward move (3 bearish candles) |
| Zone location | Below current price — candle 1 high to candle 3 low | Above current price — candle 3 high to candle 1 low |
| Acts as | Support on retest | Resistance on retest |
| Trade direction | Buy when price returns to the zone | Sell when price returns to the zone |
| Invalidated when | Price closes fully below the FVG | Price closes fully above the FVG |
FVG vs Regular Gap
A traditional chart gap (common on daily charts between sessions) and an FVG are related but not the same. A traditional gap is an overnight price jump between the previous close and the current open. An FVG can occur within a session on any timeframe — it is about the relationship between three candles, not about session boundaries.
Timeframe Hierarchy: Which FVGs Matter Most
FVGs exist on every timeframe but carry different weight. A Daily or 4H FVG represents a significant institutional imbalance — price may travel a long distance to fill it and the reaction can be substantial. A 1-minute FVG on a quiet day is much less significant.
| Timeframe | FVG significance | Best used for |
|---|---|---|
| Daily / Weekly | Very high — major institutional imbalances | Identifying key zones for swing trades and position trades |
| 4H | High — strong directional moves | Swing trade entries and targets |
| 1H | Medium — reliable intraday reference | Intraday setups and refining entries |
| 15M | Lower — good for precision entries only | Timing entries within a higher timeframe setup |
| 1M / 5M | Noise — use cautiously | Scalping entries only, within a confirmed higher TF setup |
FVGs That Overlap With Other Confluences Are the Strongest
An FVG sitting inside an Order Block, aligning with a key support/resistance level, or coinciding with a premium/discount level has multiple reasons to hold. A lone FVG with no other confluence is weaker. Always look for multiple reasons why a zone should hold before committing to a trade.
Key Takeaways
- A Fair Value Gap (FVG) is the gap between candle 1's high and candle 3's low in a three-candle bullish move — or candle 1's low and candle 3's high in a bearish move.
- FVGs form when price moves so quickly that the middle candle's range does not overlap with both surrounding candles.
- Price tends to return to FVGs to rebalance — offering a high-probability entry in the direction of the original move.
- Bullish FVGs act as support on a retest. Bearish FVGs act as resistance.
- FVGs on higher timeframes (1H, 4H, Daily) carry more weight than those on lower timeframes.
