Second test of the London high: why I'd rather trade the retest than the first touch

When price runs into a level for the first time, everyone is watching it. Breakout traders are waiting to buy above, faders are waiting to sell into it, and stops are sitting just beyond. The first touch is noisy because all of that gets triggered at once, and the candle that results often tells you very little.

The second test is different. By then you've seen how price behaved on the first touch. Did it reject cleanly and fall a fair distance, or did it hover just under and grind? Did the pullback between touches hold a higher low, or did it lose ground? That information is the whole reason I wait.

If the first test produced a strong rejection and the second test arrives on weaker momentum, smaller candles and less range, that leans toward the level holding again. If the pullback was shallow and price comes back fast with bigger candles, that leans toward a break.

The cost of waiting is real. Some levels never get a second test and you just miss the move. I'm fine with that. A missed trade costs nothing, and the second test gives me a stop location that actually means something, beyond the high of the first reaction rather than a guess.

How many of you treat the first touch as information only?

One thing that changes the read is time between the two tests. If the second test comes within a few candles, it's often the same order flow still working and the level is likely to give way. If it comes an hour or more later, the participants are different and the earlier rejection is a more relevant guide. I'd also note whether a news release sits between the two touches. A level that held before a data print can behave completely differently after it, so I treat that as a fresh first test rather than a second one.

A question on stops: if the second test pokes slightly above the first high before turning, does that invalidate the setup for you, or is it the setup? Some people would say a small overshoot of the first high is exactly the sweep they want before selling. Others would call it a sign the level is weakening. I'd lean toward needing a close back below the first high on the entry timeframe before taking it, which handles both cases, but I know some traders here prefer entering on the overshoot itself with a tighter structure.
