EURUSD grinds sideways for three days between 1.0780 and 1.0850, then breaks below 1.0780 on a Tuesday morning with a sharp red candle. Fresh shorts pile in, confident the range has finally resolved down. Within twenty minutes price is back above 1.0780, within the hour it is at 1.0810, and by the afternoon it trades to 1.0890, well above the top of the old range. Every short from the breakdown is now trapped and covering, which is exactly the fuel that carried price through the range's ceiling.
What the trap looks like as it springs
A genuine trap has a specific shape. The initial break is often thin: a decent-looking candle, but without the follow-through of a real breakdown, meaning the next candle or two fails to extend the move and instead stalls just below the broken level. Momentum, where visible, tends to fade rather than build on the break, which is the same difference between acceptance and rejection at a level discussed elsewhere. The reclaim itself is usually fast: price crosses back above the broken level within a handful of candles, not days later, because the trapped shorts are covering in a hurry rather than calmly exiting.
Why the mechanics favor the reclaim
The break creates a specific population of new short positions, all of them stopped out or defensive the moment price trades back above their entry. Covering a short means buying, and a cluster of shorts covering at roughly the same price creates real upward pressure independent of any new buyers showing up at all. This is the same trapped-crowd logic behind a broken level flipping from resistance to support once price reclaims it, just compressed into a shorter, sharper window because the initial break failed so quickly.
A worked setup
Using the EURUSD example: the break below 1.0780 stalls after one candle, with the next candle already showing a long lower wick back toward 1.0790. Entry trigger: a close back above 1.0780 on the working timeframe, confirming the reclaim rather than a mere wick poke above it. Stop: below the trap's low, around 1.0765, a 15 pip risk, placed there because a fresh move back below that low would mean the shorts were not actually trapped and the breakdown may be real after all. Target: the top of the prior range near 1.0850, with a further extension possible if momentum carries through it. Invalidation: a close back below the reclaim level, in this case 1.0780, with a following candle continuing lower, which says the reclaim failed and the original breakdown deserves more credit than the trade gave it.
The discipline of waiting for the reclaim, not the break
The mistake this setup punishes hardest is fading the breakdown the instant it happens, before any reclaim has actually shown itself. A break that genuinely continues will simply keep falling, and a trader who buys the first wick back above the low on hope alone is taking the same trade with none of the confirmation that made the reclaim trade work in the example above. The reclaim, the close back above the level with real follow-through, is the entire signal. Without it, this is just guessing that a breakdown is fake.
