The idea in one breath: A break of structure is a close beyond the most recent swing point in the direction of the trend. A wick through that level is price being rejected from it — which is the opposite signal, and mistaking one for the other roughly doubles your signal count while ruining all of them.
Close, not touch
The requirement is a candle closing beyond the level. This single rule does more filtering than anything else in structural analysis, and it is the one most often relaxed — usually by a trader who wants to already be in.
Not all breaks are equal
A break with displacement, on expanding volume, in agreement with the higher timeframe is a different event from a marginal close after four failed attempts. Both are breaks; only one is worth much, and grading is how you tell them apart before the outcome does it for you.
Grade this break of structure, then pick where the idea is invalid.
