The break that never closed above the range
A SET industrial name poked through a six-week high on the 15-minute chart and came back. Classroom notes on waiting for the close before treating a breakout as real.
On a Tuesday in February a trader in the second row held up a 15-minute page of a SET industrial. Price had printed a wick through the six-week high during the lunch lull, then sat back inside the range by the 14:30 candle. He had already bought the wick.
We put the page on the projector and asked one question: which close, on which timeframe, was supposed to mean the range was finished? He had not written one. The wick felt like permission.
In this classroom a breakout is a close beyond the boundary you marked before the session, on the timeframe you named before the session. A spike through the line is a probe. Probes fail often enough that we do not spend risk on them. That is not a moral rule; it is a way to keep the stop from living inside noise.
The industrial name did eventually leave the range, three sessions later, on a daily close. By then the trader's first attempt was already a scratch that had become a loss because he had widened the stop 'to give it room'. The room's homework that week was ugly on purpose: find five of your own wicks that never closed, and write the sentence you would have needed on the page before the open.
If you cannot point to the candle that would have kept you out, you are not trading a breakout. You are trading a feeling that the line was close.
