Fair Value Gap (FVG) on MT5: The Complete Guide (2026)
Fair Value Gap (FVG) on MT5: The Complete Guide
What a fair value gap is, how to spot it with the three-candle rule, and three concrete ways to trade FVGs on MetaTrader 5 : in context, not in isolation.
A fair value gap is one of the simplest ICT concepts to spot, and one of the easiest to misuse. Traded blindly, every chart is full of them. Traded in context, an FVG becomes a precise zone where price often reacts. Here’s how to tell the difference.
In this guide
1. What is a Fair Value Gap?
A Fair Value Gap (FVG) is a price imbalance created by a fast, one-sided move. Price moved so quickly that it left an area with little or no trading, an inefficiency the market often returns to « rebalance » later.
The three-candle rule
Look at three consecutive candles. An FVG exists when there is a gap between the wick of the first candle and the wick of the third candle, left open by a large middle (impulsive) candle. That untouched space between the two wicks is the gap.
Why « fair value »?
The idea: the impulsive move skipped past prices that were never properly traded. The market tends to come back to deliver « fair value » to those levels before continuing, which is why FVGs so often act as reaction zones.
2. Why FVGs matter in trading
Reaction zones
Price frequently retraces into an FVG before resuming, giving you a defined area to plan an entry.
Dynamic support/resistance
An unmitigated FVG often behaves like a fresh S/R level in line with the move that created it.
Structure confirmation
An FVG forming on a break of structure reinforces that the move was genuine, not a fakeout.
Precise risk
The gap edges give you logical stop and entry levels, so risk is measurable rather than arbitrary.
3. How to spot an FVG on MetaTrader 5 (manual)
- Step 1 : find an impulsive move: a strong candle (or run of candles) in one direction.
- Step 2 : check the wick gap: confirm space between candle 1’s wick and candle 3’s wick.
- Step 3 : draw the zone: use a rectangle to mark the gap from top to bottom.
- Step 4 : wait for the return: let price come back into the zone before acting.
4. Bullish vs bearish, mitigated vs unmitigated
Bullish FVG
Forms after a strong up-move; sits below price. Watch for a retrace down into it as a potential long zone, with the bias up.
Bearish FVG
Forms after a strong down-move; sits above price. Watch for a retrace up into it as a potential short zone, with the bias down.
Mitigated vs unmitigated is the key distinction: an unmitigated FVG has not yet been revisited, it’s « fresh » and more likely to produce a reaction. Once price has traded back through it (mitigated), the edge fades. Prioritise fresh gaps.
5. How to trade Fair Value Gaps : 3 strategies
Strategy 1 : FVG + market structure (BOS/ChoCH)
Define the trend with a break of structure, then trade the FVG that forms in that direction when price retraces into it. The cleanest, highest-probability use. (See the full ICT strategy.)
Strategy 2 : FVG + Order Block (confluence)
When an FVG overlaps an order block in line with the bias, the zone carries double weight. This confluence is one of the strongest entries in the framework.
Strategy 3 : FVG as a take-profit zone
An opposing, unmitigated FVG further along makes a logical target: price often pauses or reverses there.
Recommended timeframes
Use H4/H1 to mark the gap with the bias, and M15/M5 to time the entry.
Detect every FVG automatically
The MSOB Dashboard marks fair value gaps, order blocks, BOS and ChoCH on MT5 in real time, so you spot fresh, in-context gaps instantly instead of scanning charts by hand.
See the MSOB Dashboard →6. Detecting FVGs automatically on MT5
Marking gaps by hand across multiple pairs and timeframes is slow and inconsistent. A structure dashboard does it in real time and, crucially, filters for the ones that matter: fresh gaps, aligned with the higher-timeframe bias, near order blocks. That’s the difference between « every gap » and « the gap worth trading ».
7. Five mistakes to avoid with FVGs
1. Trading every FVG
Charts are full of gaps. Without a filter, you’ll trade noise.
2. Ignoring context
An FVG against the trend is low quality. Bias first.
3. Entering with no confirmation
Wait for a reaction or a lower-timeframe ChoCH inside the zone.
4. Forgetting the higher timeframe
An M5 gap means little against the Daily structure.
5. Misplacing the stop
Put the stop beyond the gap’s invalidation, not inside it.
8. Fair Value Gap FAQ
Are FVGs always filled?
No. Many are revisited, but not all, especially in strong trends where price keeps running. Treat the fill as a tendency, not a rule.
What’s the best timeframe for FVGs?
Higher timeframes (H4/H1) produce more reliable gaps; lower timeframes give more (and noisier) ones. Mark on HTF, execute on LTF.
What’s the difference between an FVG and an order block?
An FVG is an imbalance (a gap between wicks); an order block is the last opposing candle before an impulsive move. They often appear together, and that overlap is a strong confluence.
How do I know if an FVG is « strong »?
Fresh (unmitigated), aligned with the higher-timeframe bias, formed on a clear break of structure, and ideally overlapping an order block.
Can I automate FVG trading with an EA?
Yes : many traders detect gaps with a dashboard and either trade manually or feed the signals to an EA. Backtest any automation thoroughly first.
