Phases of price: reversal

Reversal is the end of a leg, not a bigger pullback
A reversal is a leg that stops continuing and starts trading the other way. That sounds obvious written out, but in real time it's the phase traders misdiagnose the most, because it looks like a retracement right up until the moment it isn't one anymore. I don't treat reversal as a deeper version of a pullback. It's a different event with its own conditions, and I don't call one until those conditions actually show up.
The cost of getting this backwards runs both directions. Call a reversal too early and I'm fighting a trend that was only ever pausing. Call it too late and I give back everything the pause already cost me while I waited for confirmation that arrived after the move was gone.
Sweep of a terminal pool, failure to continue
The setup I look for starts with a sweep of a terminal pool — the liquidity sitting beyond the level that's supposed to be the end of the leg. Old high, old low, the extreme the whole move was built to reach. Price takes it, which is exactly what a healthy continuation would do too. The sweep alone tells me nothing yet.
What tells me something is what happens immediately after. A continuation sweeps the pool and keeps pushing in the same direction, using the fresh liquidity as fuel. A reversal sweeps the pool and fails to continue — it takes the level, stalls, and can't produce another push in the original direction. That failure to continue is the first real signal. Not the sweep itself. The absence of anything happening after it.
On NQ this is where I slow all the way down. A high gets swept in New York, the follow-through I'd expect from a continuation doesn't show up, and price starts trading heavy underneath the level it just took. That stall is doing more work than the sweep that came before it.
The protected swing breaking is what separates reversal from a deep retracement
This is the mechanical line, and it's the same one I use to define retracement, just flipped. A retracement, no matter how deep, leaves the protected swing intact. A reversal breaks it. If price was making higher lows on the way up, the moment one of those lows gets taken out with a close through it, I'm not looking at a pullback anymore. The structure that defined the trend is gone.
Pair that break with a shift in delivery — the character of the candles changing from the large-body, small-wick push that defined the old direction to the same pattern now printing against it — and both pieces are in place. The sweep of the terminal pool told me the old direction is out of room. The break of structure plus the shift in delivery tell me the new direction has actually started. I need both, not one.
Why reversals need more confirmation than continuations
A continuation trade is agreeing with a market that's already told me what it wants, over and over, for the length of the entire leg. A reversal trade is disagreeing with all of that momentum at the exact point it's strongest — right after a sweep, right when the crowd that was right for the whole move is the most confident it's still right. That's a harder trade to be correct on, so I hold it to a harder standard before I take it.
I want the sweep, the failure to continue, the broken protected swing, and the shift in delivery, in that order, before I call it a reversal and not a retracement that's just deeper than usual. Skipping any one of those and acting early is how a reversal trade turns into fading a trend that was never done. This phase pays the most and forgives the least, and the extra confirmation I demand from it isn't caution for its own sake — it's the no-trade filter doing its job on the one phase most likely to fool me into acting without it.
