The short answer
A fair value gap is a three-candle imbalance: the middle candle moves so fast that the first and third candles never overlap. The price band between them is the FVG. Price returns to it because the market likes to fill unfinished business. The gap alone is not a trade. It becomes one when it sits inside a zone, in the direction of the trend.
Why this is the third layer of chart reading
Lesson 09 taught you where price reacts. Lesson 12 taught you what the reaction looks like. This lesson answers the question that sits between them: where did price skip a step?
An FVG is not a shape you hunt for. It is a visible footprint of a market that moved too fast. Institutions trade in size. When they push price through a level without resistance, they leave a gap behind. That gap becomes a magnet. This lesson teaches you where to find them, how to draw them, and when not to trade them.

FVG methodology cross-checked against Smart Money Concepts documentation, the LuxAlgo Price Action Concepts toolkit notes, ICT imbalance literature, and the SMC academic reviews published by TradingView and NexusFi. Fill-rate data cross-referenced with published SMC backtest studies on FX majors and index CFDs. Terminology verified — FVG, imbalance, and inefficiency describe the same three-candle pattern.
Most traders learn what an FVG is. Almost none learn how to draw it precisely, which fills actually matter, or when an FVG should be ignored. An FVG is a location. It is not a signal. This lesson teaches the location, the fill mechanics, and the confluence that turns it into a trade.
Key takeaways
An FVG is a three-candle pattern: the first and third candles do not overlap, leaving a gap.
Bullish FVG forms during an up move. Bearish FVG forms during a down move. The logic is mirrored.
Draw the band from candle 1's high to candle 3's low (bullish) or candle 1's low to candle 3's high (bearish).
Price fills the gap in three ways: full fill, 50% midpoint fill, or edge tap. Each has different odds.
The 50% midpoint is the most-watched level inside an FVG. It is where the highest-probability rejection occurs.
An FVG is not a trade on its own. It needs a zone and a trend to become one.
The strongest FVGs form after a liquidity sweep. The sweep clears stops, the displacement leaves the gap.
FVGs that form against the higher-timeframe trend are traps, not setups.
FVGs on the 1-minute chart are noise. Use them on 15m or higher.
No context, no trade. An FVG in isolation is a gap with a label.
A fair value gap is a three-candle pattern. The middle candle moves so aggressively that the first candle's high and the third candle's low never overlap. That leaves a price band the market traded through without stopping. The band is the FVG.
The gap is not a hole on the chart. It is not a literal break in price. It is a range that contains no two-sided trade — no moment where buyers and sellers met and agreed on a price. The market treats it as an unfinished step.
Three candles. One displacement. One missing band. That is the entire definition.
THE BULLISH FVG · THREE CANDLES, ONE GAP
The band runs from candle 1's high to candle 3's low · candle 2 does the work
Candle 2 does the work. The gap is the space candle 1 and candle 3 leave behind.
Common mistake
Calling any three candles an FVG. The gap only exists when candle 1's high is below candle 3's low (bullish) or candle 1's low is above candle 3's high (bearish). If the wicks overlap even slightly, there is no gap. Draw a box around nothing, trade nothing.
Why the gap exists
Markets are auctions. Price moves because buyers and sellers are disagreeing on value. Normal moves have two-sided trade: buyers absorb sellers, price grinds up. A displacement is different. It is one-sided flow — aggressive buying that clears every seller in its path without stopping to negotiate.
That kind of move leaves a footprint. The price band it skipped is a band where no agreement was ever reached. The market remembers. When price returns to that band, buyers who missed the first move get a second chance. Sellers who were steamrolled get a place to cover.
The result: price returns to fill the gap. Most of the time it fills partway. Sometimes it fills entirely. Sometimes it taps the edge and reverses. The three outcomes are not random — they follow from where the FVG sits and what surrounded it.
The same concept, three names
FVG, imbalance, and inefficiency describe the same three-candle pattern. FVG comes from ICT terminology. Imbalance is the order-flow term. Inefficiency is the market-microstructure term. Every textbook on Smart Money Concepts uses one of the three.
Use one name, consistently. Trade To The Top uses FVG in prose and headers. In charts, use the same. Do not collect terminology.
Bullish vs bearish FVG — the visual difference
Bullish and bearish FVGs are mirror images. A bullish FVG forms during an up move: candle 1 is green, candle 2 is a large green displacement, candle 3 is green. The gap runs from candle 1's high to candle 3's low.
A bearish FVG forms during a down move: candle 1 is red, candle 2 is a large red displacement, candle 3 is red. The gap runs from candle 1's low to candle 3's high.
BULLISH VS BEARISH FVG · SAME PATTERN, MIRRORED
Left: gap on an up-move · Right: gap on a down-move
Same three-candle logic. Bullish gaps fill from above. Bearish gaps fill from below.
How to draw an FVG — the 3-step rule
Every FVG in every lesson from here on is drawn the same way. Three mechanical steps. No interpretation.
The 3-step FVG rule
01
Find the three-candle sequence.
Scan for a candle that moved with visible force — larger body than the candles around it. That is candle 2. Candle 1 precedes it. Candle 3 follows it.
02
Draw the band.Bullish FVG: from candle 1's high to candle 3's low. Bearish FVG: from candle 1's low to candle 3's high. If the band has no height, there is no FVG. Skip it.
03
Extend it right.
The FVG is only live until price fills it. Extend the box to the right on your chart. Stop extending the moment price closes through the far side of the gap. The FVG is consumed at that point.
The pattern is the gap. The gap is the level. The level is what you trade.
The three fill scenarios
When price returns to an FVG, three things can happen. Each has different probabilities and different implications for the trade.
THE THREE FILL SCENARIOS · FULL, MIDPOINT, EDGE
Not every FVG fills completely · the midpoint is the most-watched level
Not every gap fills completely. The midpoint is the highest-probability rejection level.
Fill type
What price does
Implication
Edge tap
Price touches the near edge of the FVG and turns.
Strongest signal. Rejection happens before the gap is even entered.
Midpoint fill
Price enters the FVG, taps the 50% level, and reverses.
Reliable rejection. The midpoint acts as support/resistance.
Full fill
Price travels through the entire gap and exits the far side.
Weakest signal. The FVG is consumed. Trend may be breaking.
Common mistake
Treating every FVG as if it will fill to the midpoint. Edge taps happen more often than full fills. Waiting for the midpoint when the edge tap already reversed means missing the trade. Let the surrounding structure decide where you enter, not a fixed rule.
FVG and other imbalance terms
FVG sits inside a family of related concepts. Getting them confused is the second-most-common FVG mistake after drawing gaps that do not exist.
Term
What it is
How it differs from FVG
FVG
Three-candle imbalance
—
Imbalance
Any one-sided price move
Broader term. Every FVG is an imbalance, not every imbalance is an FVG.
Inefficiency
Any price band the market skipped
Same as imbalance. Microstructure term.
Liquidity void
A large single-candle price void
Drawn from one candle's wick, not three candles.
Order block
The last opposing candle before an impulse
Located at the start of the impulse, not inside it. Covered in Lesson 19.
Breaker
A failed order block that flips role
Different structure, different trade logic.
You will see traders use "FVG" and "imbalance" interchangeably. Both are correct in casual use. For this site, FVG means the three-candle pattern specifically. That is the only definition you need to trade the setups in the rest of this curriculum.
FVG + zone + trend
An FVG in isolation is a gap. It becomes a trade when it sits inside a zone, in the direction of the trend, and is created by a displacement that broke structure. Three layers. Stack all three or skip the trade.
THE FVG CONFLUENCE STACK · THREE LAYERS
FVG alone = no trade · FVG + zone = watchlist · FVG + zone + trend = trade
Three layers. Skip any one and the FVG is just a gap.
FVG trade validation checklist
1. Trend agrees. Higher timeframe structure is up for a bullish FVG, down for a bearish FVG.
2. Zone is present. The FVG sits inside a tested support or resistance zone.
3. Structure broke. The displacement that created the FVG broke the prior swing point (BOS).
4. Fresh gap. The FVG has not been touched since it formed. First touch is highest probability.
5. Timeframe is 15m or higher. Lower timeframes produce noise.
6. No news event within the trade window. Check the calendar before entry.
When FVGs fail
Four situations turn an FVG into a losing trade. Learn to spot them before entry.
When FVGs fail
Against the higher-timeframe trend. A bullish FVG in a daily downtrend is a pullback trap. The gap will fill, and price will continue lower. Trade with the daily, not against it.
No zone, no anchor. An FVG in the middle of an empty chart has no reason to hold. The zone is what gives the FVG its footing. Skip gaps that are not anchored.
Created by news, not by structure. A gap formed during a CPI release or rate decision is a volatility spike, not a displacement. The wick is a spike, the body is a gap fill — not the institutional footprint you are looking for.
Too many touches. An FVG that has been touched once, twice, three times is not fresh. Each touch consumes the liquidity inside the gap. The first touch is the trade. Everything after is leftovers.
If you remember nothing else: trend first, zone second, FVG third, and freshness last. Any layer missing means skip the trade.
Trading an FVG — the setup
Here is the full setup in one worked example. EURUSD 4H. Daily trend up. Price rallies off support, leaves a 3-pip FVG behind, retraces to fill it, and continues higher.
Worked example — bullish FVG at a support zone
Instrument

Stop
1.0848 (below the zone)
Target

R:R
2.7 : 1
Candle 1 high: 1.0855. Candle 3 low: 1.0858. FVG band = 1.0855 to 1.0858.
Price retraces. Taps the midpoint at 1.0856.5. Rejects with a bullish candle.
Entry on the close of the rejection candle at 1.0858.
Stop 1.0848. Target 1.0885 over the next 12 candles.
Result: +27 pips, 2.7R winner.BULLISH FVG AT SUPPORT ZONE. TRADE WORKS.
WORKED EXAMPLE · BULLISH FVG AT SUPPORT ZONE
EURUSD 4H · rally leaves the gap · retrace fills to midpoint · rejection continues the trend
The FVG filled to the midpoint. Zone held, trend continued, target hit.
The FVG is the entry. The zone is the reason. The trend is the direction.
In one box
FVG = three candles where candle 1 and candle 3 do not overlap.
Bullish FVG: band from candle 1's high to candle 3's low.
Bearish FVG: band from candle 1's low to candle 3's high.
Three fill types: edge tap (~75%), midpoint (~61%), full fill (~49%).
FVG alone is not a trade. Stack with zone and trend.
Freshness matters. First touch is the trade. Every subsequent touch is leftovers.
Trend is the filter. Counter-trend FVGs are traps, not setups.
Displacement must break structure. A gap that forms inside a range is noise.
Timeframe floor is 15m. Below that, FVGs are noise.
No zone, no anchor. Gaps in empty space have no reason to hold.

5 questions · immediate feedback · retake any time
Question 01 of 05
What defines a fair value gap?
Correct: C. A fair value gap is a three-candle pattern. The middle candle moves so fast that candle 1 and candle 3 never overlap, leaving a price band the market skipped.
Question 02 of 05
Where is the FVG band drawn on a bullish setup?
Correct: B. Bullish FVG runs from candle 1's high to candle 3's low. Bearish FVG is the mirror — from candle 1's low to candle 3's high.
Question 03 of 05
Which fill scenario is the strongest signal?
Correct: C. An edge tap is the strongest signal — rejection happens before the gap is even entered. Full fill is the weakest, because it suggests the trend may be breaking.
Question 04 of 05
What three layers must line up for a tradeable FVG setup?
Correct: A. Trend gives direction. Zone gives the anchor. FVG gives the entry. Skip any one and the setup is a guess.
Question 05 of 05
Which FVG is the most reliable?
Correct: B. Freshness and displacement are the two biggest factors. A fresh FVG formed by a structure-breaking displacement is the highest-probability setup. Every touch consumes liquidity — the first touch is the trade.
