Fair value gap (FVG): meaning, real vs fake and a trading strategy
Fair value gap meaning
A fair value gap (FVG) is a three-candle pattern where the middle candle moves so fast that the wicks of the candles on either side do not overlap. The space left between candle 1 and candle 3 is the gap. Price passed through that area in one direction only, so very little two-way trade happened there.
The fair value gap meaning, in plain words: the market moved faster than it could find a fair price. One side, buyers or sellers, overwhelmed the other. In Smart Money Concepts, such gaps are watched because price often returns to them to "rebalance" before continuing.
Bearish FVG: high of candle 3 < low of candle 1 → gap = candle 3 high to candle 1 low
Consequent encroachment (CE) = (gap top + gap bottom) / 2
Why fair value gaps form
One-sided order flow
When a large participant hits the market aggressively, or when news triggers a rush of stop-loss orders, price jumps across several levels with few resting orders filled in between. The candle that does this is called the displacement candle.
Why price tends to revisit the gap
Areas with thin trading leave unfilled interest behind. Traders who missed the move may place orders there; the participants who caused the move may want to add more at better prices. That is why a revisit, or "fill", of the gap is common, although not certain. On a volume profile, an FVG often lines up with a low volume node, which is the same idea seen through volume.
How to identify a fair value gap step by step
- Find a large candle with a big body compared with recent candles.
- Look at the candle before it (candle 1) and after it (candle 3).
- Bullish FVG: the low of candle 3 is above the high of candle 1. The gap runs from candle 1's high up to candle 3's low.
- Bearish FVG: the high of candle 3 is below the low of candle 1. The gap runs from candle 3's high up to candle 1's low.
- Mark it forward as a box until price trades back into it.
Only wicks count. If candle 3's wick dips into candle 1's wick, there is no FVG, however big the middle candle looks.
Imbalance vs FVG: are they the same?
Many traders use "imbalance" and "FVG" as the same thing, and in day-to-day SMC language that is mostly fine. Strictly speaking there are differences:
| Term | What it describes |
|---|---|
| Fair value gap | The three-candle wick gap between candle 1 and candle 3 |
| Imbalance (price) | Broad term for any one-sided move; some use it only for body-to-body gaps where wicks still overlap |
| Liquidity void | A long run of consecutive FVGs, a large stretch traded in one direction |
| Order flow imbalance | A footprint concept: ask volume much larger than bid volume diagonally at a price level |
The last one is different. An order flow imbalance is measured from traded volume on a footprint chart, not from candle shapes. When a price FVG and stacked footprint imbalances appear on the same candle, the one-sided nature of the move is easier to trust.
Consequent encroachment: the 50% level
The midpoint of a fair value gap is called consequent encroachment (CE). It is a widely used reference inside the gap.
- If price fills a bullish FVG only down to the CE and then turns up, the gap is generally seen as respected.
- If a candle closes through the CE, many traders treat the gap as weakening.
- If a candle closes beyond the far edge, the gap is considered fully filled and may flip into an inverse fair value gap.
Wicks through the CE are common and less meaningful than closes. Pay attention to how the candle finishes.
Real vs fake FVG: what makes a verified fair value gap
Gaps appear all the time on 1-minute charts, so most are noise. A gap traders consider "real" or verified usually ticks several of these boxes:
- It caused a structure break: the displacement closed beyond a swing high or low (BOS or CHoCH).
- Size relative to volatility: the gap is meaningful compared with average candle range or ATR, not a one-point sliver.
- Volume behind it: the displacement candle had above-average volume and one-sided delta.
- Trend alignment: a bullish FVG in a higher-timeframe uptrend, in the discount half of the range.
- Born after a liquidity sweep: the move began right after stops were taken, as described in liquidity sweep.
- Fresh: not yet traded into.
Signs of a fake or weak FVG
- It forms in a tight sideways range with no structure change.
- It is tiny compared with normal candle size.
- The displacement candle had low volume, for example in a lunch-hour lull.
- It forms against a strong higher-timeframe trend.
- It appears right at the 9:15 IST open from a gap-up or gap-down, where the first candles are often erratic.
Fair value gap and order block together
Fair value gaps and order blocks are two parts of the same story. The order block is the last opposite candle where the move started; the FVG is the inefficiency the move left right after.
A typical sequence: price sweeps a low, an order block forms, displacement breaks structure and leaves an FVG. On the pullback, price may react at the top of the FVG, at its CE, or go all the way to the order block. Traders often treat the FVG as the first area of interest and the order block as the deeper level, with invalidation beyond the order block.
FVG trading strategy: a step-by-step framework
- Set the bias on a higher timeframe (1-hour or 15-minute). Note the trend and where liquidity sits.
- Wait for displacement that breaks structure in the direction of that bias and leaves a clear FVG.
- Mark the gap and its CE.
- Let price come back. Avoid chasing the displacement candle.
- Watch the reaction inside the gap on a lower timeframe: rejection wicks, a small CHoCH, or absorption on the footprint.
- Invalidation: a close through the far edge of the gap, or below the related order block.
- Targets: the next opposing liquidity, such as the high that started the pullback or equal highs above.
Combining the gap with the Fibonacci OTE zone or with VWAP is common. Trading F&O carries a high risk of loss; this FVG trading strategy is a study framework, not a promise of results.
FVG trading example on NIFTY
The prices below are an illustration, not a record of a real day.
On a 5-minute NIFTY chart, price slides from 24,620 to 24,555 between 9:45 and 10:30 IST, taking out the opening low of 24,560. Then a large green candle runs from 24,558 to 24,610.
- Candle 1 (before) high: 24,572
- Candle 2 (displacement): 24,558 to 24,610
- Candle 3 (after) low: 24,594
The bullish FVG is 24,572 to 24,594. CE = (24,572 + 24,594) / 2 = 24,583. The move also closes above the swing high at 24,600, a BOS.
Around 11:20 IST price pulls back to 24,586, just above the CE, and the footprint shows sellers hitting the bid without moving price lower. A 1-minute CHoCH follows and NIFTY returns towards 24,620. If a 5-minute candle had closed below 24,572, the gap would have been treated as failed, and traders would watch the zone for an inverse FVG instead.
BANKNIFTY bearish FVG
A similar pattern in reverse on BANKNIFTY: a red displacement candle from 52,300 to 52,150 leaves a gap between candle 3's high at 52,210 and candle 1's low at 52,260. CE is 52,235. A later rally that fails near 52,240 shows sellers defending the gap.
Filled, mitigated and inverted gaps
- Untouched: price has not returned. Most relevant.
- Partially filled / mitigated: price entered the gap and reacted. Many treat it as used after the first reaction.
- Fully filled: price traded through the whole gap. Usually of little use in the original direction.
- Inverted: price closed through the gap and then used it from the other side. See inverse fair value gap.
Common FVG mistakes
- Marking every tiny gap on the 1-minute chart.
- Ignoring which direction the higher timeframe is trending.
- Treating wick touches through the CE as invalidation instead of watching closes.
- Entering with a fixed order in every gap without waiting for a reaction.
- Forgetting that expiry-day option flows and news can blow through gaps.
- Risking too much because the zone "looks perfect". Size every trade from your stop, not your confidence.
Seeing it on the TradingMarble chart
The TradingMarble chart draws fair value gaps, order blocks and structure breaks on NIFTY, BANKNIFTY and other F&O underlyings, with a live footprint underneath. That makes it easier to study how price and order flow behave when a gap is revisited. The plans are listed on the pricing page.
Fair value gap checklist
- Three candles with no wick overlap between candle 1 and candle 3?
- Did the displacement break structure?
- Is the gap meaningful compared with normal candle size?
- Was there strong volume and one-sided delta?
- Does it agree with the higher-timeframe bias and sit in the right premium or discount area?
- Is it fresh, and where is the CE?
- Where is invalidation, and is risk sized?
A fair value gap is a simple pattern with a solid idea behind it: fast, one-sided moves leave inefficiency that the market often revisits. Filter gaps by structure, size and context, and the fair value gap becomes a clear map of where to pay attention.
Frequently asked questions
What is a fair value gap in trading?
A fair value gap is a three-candle pattern where the wicks of the first and third candles do not overlap, leaving an empty area beside the large middle candle. It shows that price moved through that range in one direction with little two-way trade. Traders watch these gaps because price often returns to them before continuing.
Is FVG the same as imbalance?
In everyday Smart Money Concepts language, yes, the terms are often used interchangeably. Strictly, an FVG is the specific three-candle wick gap, while imbalance is a broader word for any one-sided move. On a footprint chart, an order flow imbalance means something different: ask volume much larger than bid volume at a price level.
What is consequent encroachment in a fair value gap?
Consequent encroachment, or CE, is the 50% midpoint of a fair value gap. Many traders use it as a key reference: if price reacts at or before the CE, the gap is seen as respected. A candle closing through the CE is often read as a sign the gap is weakening.
How do you know if an FVG is real or fake?
A stronger FVG usually comes from displacement that breaks market structure, is large compared with normal candle size, has heavy volume, and forms in the direction of the higher-timeframe trend, often after a liquidity sweep. Weak gaps are tiny, appear inside choppy ranges, or form on low-volume candles.
Do all fair value gaps get filled?
No. Many gaps are revisited, but not all, and some are only partly filled. In strong trends, price can leave gaps behind for a long time. Treat a fair value gap as an area of interest, not a level that price must return to.
What is the difference between a fair value gap and an order block?
An order block is the last opposite-colour candle before a strong move; it marks where the move began. A fair value gap is the empty area left by the move itself. They often appear together, with the FVG sitting just beyond the order block.
