Displacement is the engine behind order blocks, fair value gaps and supply zones, so learning to see it is genuinely useful. Whether it predicts anything is a different question, and the answer is no.
Displacement is a candle several times larger than its neighbours and almost all body — the mark of conviction arriving, which is not the same as a forecast that more is coming.
Displacement is a candle that is far bigger and far more decisive than the ones around it. Mostly body rather than wick, closing near its extreme, several times the size of recent candles.
It matters because it is the engine behind several other concepts in this series. The candle that creates a fair value gap is a displacement candle. The move that leaves an order block behind is displacement. The departure from a demand zone is displacement. Learning to see it is genuinely useful.
The question this page asks is narrower and more awkward: does a displacement candle mean the move continues?
A quiet room, and suddenly someone shouts. You now know something happened. What you do not know is whether more shouting follows or whether that was the whole event.
Displacement is the shout. It tells you conviction arrived — a lot of orders went through in one hour. It does not tell you there is more where that came from, and treating loudness as a forecast is the mistake this lesson is about.
Every candle in five years of hourly data was sorted into decisive or ordinary, then followed forward with the same test: did price travel another full body in the same direction before retracing to the candle's open?
| Instrument | Displacement candles | Followed through | Ordinary candles | Followed through |
|---|---|---|---|---|
| XAUUSD | 2,518 | 50.2% | 20,270 | 48.9% |
| GBPUSD | 2,955 | 50.4% | 20,273 | 48.1% |
| EURUSD | 2,895 | 49.7% | 20,452 | 48% |
| US30 | 2,127 | 50.3% | 13,794 | 50.2% |
| NAS100 | 2,204 | 51.3% | 14,190 | 50.3% |
What was counted: A displacement candle has a body at least three times the median body of the previous twenty candles, and that body is at least 60% of its own high-to-low range. Follow-through means price travelled another full body in the same direction within twelve hours before retracing to the candle's open. Every candle failing the size test is counted as the control.
The test is scaled to each candle: the target and the invalidation both sit one body away from the close, so a large candle is asked for a proportionally larger move. Cases where a single hourly bar reached both are discarded as undetermined.
There is essentially no difference. Displacement candles continued around 50.2% of the time; ordinary candles around 48.9%. Both are close to a coin flip, on every instrument, across tens of thousands of candles.
A big decisive candle tells you something real happened. It does not tell you the move has further to go — at least not in proportion to its own size, which is the only way the question can be asked fairly.
The first version of this test scored a bar that reached both the continuation target and the invalidation as a success, because it happened to check that branch first. For a large displacement candle the two thresholds are far apart, so this was rare. For an ordinary candle they sit within a pip or two of the close, so almost every ordinary candle was ambiguous — and every one of them was being counted as follow-through.
That inflated the control to 65% and produced a headline result that displacement candles continue less often than ordinary ones. It was a bug, not a finding, and it was a plausible-looking one. Discarding the ambiguous cases gives the honest answer above: no meaningful difference.
The general lesson is worth more than the specific one. Backtests fail this way constantly and quietly — a rule about which condition gets checked first, a fill assumed at the better price, a bar counted twice. The result looks reasonable, so nobody questions it. If a backtest tells you something surprising, suspect the code before you believe the market.
Quite a lot, once you stop asking it to predict.
Yusuf sees gold print a huge green hourly candle at 13:00 — around five times the size of the previous few.
The instinct. Buy. Something big is happening and he does not want to miss it.
What the data says about that. Roughly a coin flip whether price travels another candle's worth before coming back through the open. And to survive that pullback his stop would have to sit below the entire candle — the widest stop available, taken at the highest price.
What he does instead. He treats the candle as a signpost, not a signal. He marks three things: the order block behind it, the fair value gap inside it, and the level it broke. Each of those is a place to act later, at a better price, with a defined invalidation.
The part that pays. Two hours on, price pulls back into the gap. He now has the same directional idea with a fraction of the risk. The displacement told him where to look. It never told him when to buy.
This page's first answer was wrong because of one line of code. Yours might be too. Replay hourly candles, mark the decisive ones, and record what followed — then do the same for ordinary candles as a control. Two numbers, and you will trust them far more than either of ours.

What is displacement in trading?
A candle far larger and more decisive than the ones around it — several times the recent average size, mostly body rather than wick, closing near its extreme. It is the move that creates fair value gaps, order blocks and supply and demand zones.
Does a displacement candle mean price will continue?
No, not measurably. On gold, decisive candles travelled another full body in the same direction 50.2% of the time before retracing to the open; ordinary candles did so 48.9% of the time. Both are close to a coin flip, on every instrument tested.
Then why does displacement matter at all?
Because of what it marks rather than what it predicts. Find displacement and you have found the order block behind it, the fair value gap inside it, and the level it broke — each of which is a place to act later at a better price with a defined invalidation. It is an excellent signpost and a poor signal.
How big does a candle have to be to count?
The definition used here is a body at least three times the median body of the previous twenty candles, and that body at least 60% of the candle's own range. The second condition matters — a large candle that is mostly wick is indecision, often a sweep, which is close to the opposite of displacement.
Should I ever enter on the displacement candle itself?
It is the worst available price in the move with the widest stop, on something that continues about half the time. Most traders do better marking what the candle created and acting on the pullback into it.
Why does this page talk about a bug in its own measurement?
Because the first version of the test scored ambiguous bars as successes and produced a confident, plausible, wrong answer. That failure mode is extremely common in backtesting and almost never visible in the output. If a test tells you something surprising, suspect the code before you believe the market.
Run the comparison yourself — decisive candles against ordinary ones — and pay close attention to how you score the bars that hit both thresholds. That single decision changes the answer, and it is the most valuable thing on this page.
