Equal highs (two or more swing highs at nearly the same price) and equal lows look like clean support/resistance — and that's exactly why they become liquidity targets. Traders place breakout orders and protective stops just beyond a level that's been tested twice, so equal highs/lows build a pool of resting orders that the market is drawn to sweep.
Why equal highs get taken
A double-tested level looks like strong resistance, so shorts stack their stops above it and breakout traders queue orders there. That concentration of liquidity is fuel — and price is often drawn toward equal highs specifically to trigger it (a liquidity sweep). The “obvious” double top is obvious to everyone, which is what makes it a target rather than a wall.
How to use them
Two ways. As a magnet: equal highs/lows tell you where price is likely drawn next — unswept equal highs above are a target for a push up. As a reversal setup: watch for the sweep of the equal highs (a spike past and reclaim) as a fade back down. Don't blindly short a “double top” at equal highs — the level often gets swept first; trade the reaction after the sweep, not the level itself.
Equal highs aren't a ceiling — they're a pool of stops with a target painted on them. Expect the sweep, then trade the reversal.
The frame
Equal highs/lows are a structural read on where liquidity rests, not a signal to fade the level on sight — the whole point is that the obvious level gets taken. They're strongest combined with the dealer map: equal highs sitting under a call wall is a spot where a sweep is both likely and, once rejected, a strong fade. Read them to anticipate where price is drawn, and trade the sweep's aftermath.
