Zone width: pencil rules we actually use

A hairline at a single price looks precise and fails often. A band that covers half the recent swing looks “safe” and never triggers a plan. In the intensive we start from the body cluster of two or more touches, then expand only to the extreme wicks that rejected from that cluster.

On daily charts of liquid equity indices we rarely allow a zone wider than roughly one average true range of the last twenty sessions. On four-hour FX pairs the same idea applies with that timeframe’s ATR. If your zone needs to be wider to capture the touches, you are probably mixing two structures — split them or drop the weaker one.
