Rising channels often print brief spikes through the upper rail during strong sessions. Readers who fade every spike redraw constantly. In Channel Clinic we isolate that habit.
Ask what the lower rail is doing
If the lower rail still attracts closes and the channel width is stable, an upper spike is frequently a probe. Watch whether the next two closes return inside and whether volume or range on the spike was unusual for that name.
Width expansion
Sometimes the “false break” is really the start of a wider channel. Before calling failure, try projecting a new parallel from the spike high; if the new upper rail then gathers two clean reactions, the old width may simply have been too tight.
Classroom caution
We do not teach automatic short entries at upper rails. The lesson is descriptive: label the event, update the geometry if needed, and only then decide whether your own plan cares. Structure literacy and trade decisions stay on separate pages of the worksheet on purpose.
