Why Is the Price Reversing After Hitting My Stop Loss?

The price reverses right after hitting your stop loss because your stop was part of a crowd, and that crowd is exactly what a large buyer needs. Stops sitting together just below an obvious low are a pile of sell orders waiting to fire. Whoever wants to buy size cannot do it without sellers, so the price is drawn down into that pile, the stops are triggered, the buying absorbs them, and the market turns. Traders call it a liquidity sweep or a stop hunt. Nobody targeted you personally — nobody knows you exist.
Why a pile of stops is worth going to get
Imagine trying to buy every ticket to a sold-out concert. You cannot, unless something makes a lot of holders sell at once. A dip below a well-known low does precisely that: it converts a thousand patient stop orders into market sells, and for a few seconds there is real supply to buy from. That is why the wick goes just far enough to clear the level and no further. The sweep was the point; the low was never the destination.
How to tell a sweep from a real breakdown
A sweep is fast, leaves a long wick, and price closes back above the level within a candle or two, often on a spike of volume. A genuine breakdown is slower, and price spends time below the level rather than snapping back. On a block explorer you cannot see this, but every exchange chart shows it: look at where the candle closed, not how far it poked. If it closed back inside the range, the move was almost certainly a liquidity grab.
What to do about it
Not removing your stop — that trades a small, known loss for an unlimited one, and on leverage it hands the decision to the exchange's liquidation engine instead. The fix is placement: put the stop beyond the level the crowd is watching, not just past it, and size the position down so the wider stop still risks the same money. On a lower-leverage position, a wide stop is affordable.
If this keeps happening on trades you were right about, the pattern is worth reading properly: see why you keep getting stopped out on good setups, and what to do when the trade runs without you.
