Arrive with two instruments you actually trade or analyze. Instructors prefer familiar markets because your labeling habits show more clearly than on a random exotic chart.
Print or export a clean price pane without strategy overlays. Keep volume if you use it for character notes, but remove moving averages and oscillators for the first marking round.
Sketch a light pencil count at home if you wish, then bring an unmarked duplicate. Clinics often ask you to restart on the clean sheet so instructors can watch the sequence of decisions rather than only the finished ink.
Note your contested segments in a short list: wave twos that feel too shallow, fourth waves that brush first-wave territory, triangles that may still be expanding. That list becomes the agenda for your individual critique.
Leave signal alerts and brokerage screens closed during the session. The clinic scores annotation craft. Execution decisions belong outside the teaching room.
