What Are Fair Value Gaps? How to Trade FVGs

Fair value gaps are one of the most practical concepts in the Smart Money Concepts (SMC) framework. They represent areas on a chart where price moved so aggressively that it left behind an imbalance -- a zone where one side of the market completely overwhelmed the other. Traders use these gaps as potential entry zones because price has a tendency to return and fill them before continuing in the original direction.

What Is a Fair Value Gap?

A fair value gap is a three-candle pattern where the middle candle's range creates a gap between the wicks of the first and third candles. Specifically:

• Bullish FVG: The low of candle 3 is higher than the high of candle 1. The space between those two levels is the gap. The middle candle (candle 2) is a large bullish candle whose body spans that gap zone.

• Bearish FVG: The high of candle 3 is lower than the low of candle 1. The middle candle (candle 2) is a large bearish candle, and the space between candle 1's low and candle 3's high is the gap.

The gap itself is the price range that was traded through on a single candle without any opposing price action to create overlap. In a balanced market, candle wicks overlap significantly from bar to bar. When they do not, an imbalance exists.

Think of it this way: the middle candle moved so fast that the surrounding candles could not "reach" into that price range. That untested zone is the fair value gap.

Why Fair Value Gaps Form

Fair value gaps are created by aggressive institutional order flow. When a large participant enters the market with significant size -- or when a high-impact news event triggers a rush of orders in one direction -- price moves rapidly. There are simply not enough resting orders on the other side to absorb the momentum.

In a normal, balanced market, buyers and sellers trade back and forth at each price level, creating overlapping candle wicks. When one side dominates, price skips through levels without this two-way auction taking place. The result is a gap in the price delivery.

This matters because markets tend to seek efficiency. The theory behind FVG trading is that price will often return to these inefficient zones to "rebalance" -- to allow the two-way auction that was skipped during the aggressive move. Once rebalanced, price can continue in the direction of the original move with a more stable foundation.

Bullish vs. Bearish Fair Value Gaps

Bullish fair value gaps

A bullish FVG forms when price rushes upward. The three-candle sequence looks like this:

1. Candle 1 -- any candle that establishes a reference high (the wick high)
2. Candle 2 -- a large bullish candle that drives price sharply higher
3. Candle 3 -- opens and trades above, with its low remaining above candle 1's high

The gap zone sits between candle 1's high and candle 3's low. This is the area price blew through without opposition.

Bullish FVGs act as potential support zones. When price pulls back into this gap, buyers may step in to defend the zone, providing a long entry opportunity.

Bearish fair value gaps

A bearish FVG is the mirror image. Price rushes downward:

1. Candle 1 -- establishes a reference low
2. Candle 2 -- a large bearish candle driving price sharply lower
3. Candle 3 -- opens and trades below, with its high remaining below candle 1's low

The gap zone sits between candle 3's high and candle 1's low. Bearish FVGs act as potential resistance zones where sellers may defend the level on a retest.

How to Identify Fair Value Gaps on a Chart

Finding FVGs manually follows a simple process:

1. Scan for large-bodied candles -- These are your candidates for candle 2 in the pattern. Look for candles that are significantly larger than their neighbors.

2. Check the surrounding wicks -- Compare candle 1's high to candle 3's low (for bullish) or candle 1's low to candle 3's high (for bearish). If there is a visible space between them, you have an FVG.

3. Mark the zone -- Draw a rectangle covering the gap between those two wick levels. Extend it to the right so you can see when price returns to the zone.

4. Note whether the gap has been filled -- If price has already returned and traded through the entire gap zone, it is considered filled (or mitigated). Unfilled gaps are the ones with active trade potential.

On lower timeframes, you will find FVGs frequently. On higher timeframes (4-hour, daily, weekly), they are less common but tend to carry more significance because they represent larger institutional moves.

How to Trade Fair Value Gaps

The core trading logic behind FVGs is straightforward: price tends to return to fill the gap before continuing in the original direction. This creates a retracement entry opportunity.

Entry approach

1. Identify a clear FVG in the direction of the higher-timeframe trend
2. Wait for price to retrace into the gap zone
3. Enter when price reaches the gap -- either with a limit order at the edge of the gap zone or after seeing a lower-timeframe reaction (rejection candle, structure shift)
4. Place your stop loss beyond the opposite side of the gap. For a bullish FVG, the stop goes below the bottom of the gap zone. For a bearish FVG, the stop goes above the top of the zone.
5. Target the next significant level -- a previous swing high/low, a liquidity pool, or an opposing FVG

Partial fills vs. full fills

Not every FVG gets fully filled. Sometimes price enters the gap, reacts at the midpoint or the edge, and reverses. Other times price fills the entire gap and continues through it, invalidating the zone. There is no guarantee that a gap will hold.

Many traders use the 50% level of the gap as a key decision point. A reaction at or above the 50% mark (for bullish FVGs) suggests the zone is being respected. A clean break through the entire gap suggests the zone has failed.

The strongest fair value gaps are the ones aligned with the prevailing trend on a higher timeframe. An FVG that forms during a pullback within a larger uptrend is more likely to act as support than one that forms against the trend.

Fair Value Gaps vs. Traditional Gaps

Traditional chart gaps -- the visible spaces between one candle's close and the next candle's open -- are well-known in technical analysis. They appear most commonly on daily charts of stocks when overnight news causes price to open at a different level than the previous close.

Fair value gaps are different in several important ways:

• FVGs are intra-candle imbalances, not opening gaps. They exist within a continuous price stream where wicks fail to overlap.
• FVGs appear on all timeframes, from 1-minute to monthly charts. Traditional gaps are primarily a daily-chart phenomenon tied to market open/close cycles.
• FVGs can exist even when there is no visible "space" on the chart at first glance. You need to compare candle 1 and candle 3 wicks specifically to identify them.
• Traditional gaps are created by time-based market closures (overnight, weekends). FVGs are created by order flow imbalance during active trading.

Both types of gaps share the underlying concept that price tends to revisit these areas, but the mechanics behind why they form are fundamentally different.

Common Mistakes When Trading FVGs

Trading every FVG you find

FVGs form constantly, especially on lower timeframes. If you trade every single one, most will be low-probability setups that get stopped out. Focus on FVGs that:

• Align with the higher-timeframe trend direction
• Were created by a strong displacement move (large candle 2 relative to surrounding candles)
• Have not already been partially filled or tested
• Sit near other confluent levels (order blocks, key support/resistance, round numbers)

Ignoring trend context

A bullish FVG that forms during a strong daily downtrend is a counter-trend setup. It may fill and hold temporarily, but the probability of a sustained reversal from that single gap is low. Always check the higher timeframe bias before assigning significance to an FVG.

Expecting perfect fills

Price does not always return to fill every gap, and when it does, it does not always fill the gap perfectly to the tick. Some gaps get filled immediately on the next candle. Others take days or weeks. Some never get filled because the trend is too strong. Build your trade plan around probabilities, not certainties.

Using FVGs in isolation

FVGs work best as part of a broader analysis framework. Combine them with market structure analysis, order blocks, supply and demand zones, and volume context. An FVG that sits inside a higher-timeframe order block is a much stronger setup than an FVG floating in no-man's land.

How Automated FVG Indicators Help

Scanning for fair value gaps manually across multiple symbols and timeframes is tedious. You need to check every three-candle sequence, compare wick levels, and keep track of which gaps have been filled. Automated indicators handle all of this in real time:

• Detect FVGs automatically as each new candle closes, checking the three-candle criteria instantly
• Plot gap zones on the chart as colored rectangles so you can see exactly where the imbalance sits
• Track fill status -- updating or removing gap zones once price has retraced through them
• Work on any timeframe -- apply the same indicator from 1-minute scalping charts to weekly swing trading charts
• Scan multiple symbols -- RadarScreen-based FVG scanners can monitor your entire watchlist and alert you when a new gap forms or an existing gap is being tested

This frees you from the mechanical work of gap identification and lets you focus on context analysis, entry timing, and risk management -- the parts of trading that actually require judgment.
