Floor 3: Imbalance
What is displacement in trading?
Displacement is a candle, or a short run of candles, that moves price far and fast with large bodies and small wicks. ForexLens measures it: the body must be at least twice the average range of the ten candles before it, and at least 60% of its own range. SMC traders read it as urgency.
How to spot it
Charts alternate between drifting and lunging. Displacement is the lunge: a candle that is visibly out of scale with what came before it, travelling in one direction from open to close with little hesitation. SMC traders read it as a sign that one side was willing to pay up to get filled, and they treat it as the thing that gives other concepts their weight. An order block is defined by the displacement that follows it, a fair value gap is usually left by it, and a structure break caused by it is taken more seriously than one that drifts through a level.
"Big" is relative, so the first test compares the candle with its own recent past. A 15 pip body is enormous in a quiet Asian session and ordinary after a news release. Measuring the body against the average range of the preceding candles adjusts for that automatically.
The second test is about shape. A candle can have a huge range and still close near where it opened, with long wicks on both sides. That is volatility, not displacement: price went a long way and came back. Displacement requires the body, the distance from open to close, to make up most of the candle.
The rule ForexLens uses
The rule ForexLens uses: a candle is displacement when its body is at least 2 times the average high-to-low range of the 10 candles before it, and its body is at least 60% of its own high-to-low range. Both conditions must hold. The direction is the direction of the body.
Step by step
- Measure the body of the candle: the distance between its open and its close.
- Measure the high-to-low range of each of the ten candles before it and take the average.
- Divide the body by that average. The result must be 2 or more.
- Divide the body by the candle own high-to-low range. The result must be 0.6 or more.
- If both tests pass, it is displacement. Check whether it also left a fair value gap or closed beyond a swing.
What usually comes with displacement
- A fair value gap: the candle is so large that its neighbours do not overlap. A displacement candle that leaves a gap is the classic form.
- A structure break: the move closes beyond a swing, giving a BOS or a CHoCH.
- A session open or a release: large candles cluster around the London and New York opens and scheduled news. See kill zones.
- A prior sweep: in the entry model, displacement away from a raided level is the evidence that the raid meant something.
Displacement vs noise
Three look-alikes fail the rule. A long-wicked candle has range but no body: it fails the 60% test. A large candle in an already wild stretch is normal for its surroundings: it fails the 2 times test. And a slow grind of many small candles in one direction can cover a lot of ground without any single candle standing out. That is a trend, and a perfectly good one, but it is not displacement.
The game on this topic never shows a candle close to the borderline. The chart generator leaves out the grey band between clear displacement and clear noise, because a rule with a threshold will always have marginal cases that reasonable people would call either way.
Worked example
The simulated chart below highlights one candle to rate. Before opening the Lens, estimate two things by eye: how many "ordinary recent candles" tall its body is, and how much of the candle is body rather than wick.
The generated walk-through then gives the measured values: the ratio of the body to the average range of the ten candles before it, and the body as a share of its own range. Compare them with your estimate and with the two thresholds. If a gap was left behind, the Lens draws that too.

Reading the chart, step by step
- Candle 18 has a body of 39 pips. The 10 candles before it average a high to low range of 10.8 pips, so the body is 3.6 times the average. The rule asks for at least 2.
- Its full range is 47.7 pips, so the body is 82% of the candle. The rule asks for at least 60%.
- Both tests pass: this is displacement.
- It also leaves a fair value gap behind, which is common after displacement but is not part of the test.
These numbers come from the generated chart above. Change the seed and the prices change; the rule does not.
Takeaway: Displacement is two measurements: a body at least twice the recent average range, and at least 60% of the candle itself.
Common mistakes
- Judging size without context. A candle is only large relative to the candles before it. The same number of pips can be displacement on one chart and background on another.
- Counting range instead of body. A long candle that closes back near its open shows rejection, not displacement. Measure open to close.
- Chasing the candle. By the time displacement is confirmed, it has closed and the move has happened. Entering at the end of it means the widest possible stop. SMC traders use it as context and wait for a pullback.
- Assuming it shows who was trading. A large candle tells you price moved fast. It does not tell you an institution was buying; thin liquidity and news produce the same candle.
Does it work? An honest note
Displacement is one of the more grounded ideas in SMC because it can be measured, and because something like it is recognised well beyond SMC. Momentum, range expansion and wide-range candles are old ideas, and there is academic support for momentum in many markets, currencies included. That research measures returns over months, not single candles, and it does not test this definition.
What the label adds is an interpretation: that the move reveals institutional intent. That part is not established. In spot forex a sudden large candle is just as consistent with a data release, a stop cascade or a quiet moment when few orders were resting. The thresholds are also conventions. Twice the ten-candle average and 60% body are sensible, round choices; other teachers use different numbers or none, and no study shows these particular values are special.
The useful, modest claim is that requiring displacement filters out a lot of weak setups: it stops you labelling order blocks and structure breaks in sleepy, directionless trading. Whether what remains is profitable is a separate question; see does SMC work? Measuring a move beats guessing at it, and that is as far as the evidence goes.
Questions people ask
What is displacement in SMC?
Displacement is a sudden, forceful move in one direction, shown by one or more candles with large bodies and small wicks. SMC traders read it as evidence of urgency from large participants and use it to validate other concepts, such as order blocks, fair value gaps and structure breaks.
How do you measure displacement?
ForexLens uses two tests. The candle body must be at least twice the average high-to-low range of the ten candles before it, and the body must be at least 60% of the candle own range. Other traders judge it by eye or use an indicator such as average true range. A stated threshold makes your reading repeatable.
Is displacement the same as momentum?
They are closely related. Momentum is the general tendency of a move to persist and is usually measured over many candles. Displacement is a specific, short event: one candle or a small cluster that stands out from its surroundings. You can think of displacement as a burst of momentum concentrated in a moment.
Does displacement always create a fair value gap?
Often, but not always. A gap needs the candles on either side of the large one not to overlap. If the candle before or after has a long wick reaching into the move, the wicks overlap and there is no gap, even though the candle passes the displacement test. Many traders prefer displacement that does leave a gap.
Practise it
Reading about a rule is not the same as applying it. These games generate a fresh chart each round, ask you to find it first, and grade you against the same rule.
