Reading histogram slope before the cross
The histogram often turns before the lines cross. A practical way to notice expansion and fade without chasing every tick.
Many traders wait for the MACD line to cross the signal line and miss the earlier story in the histogram. Consecutive bars that shrink toward the midline while price still extends often warn that momentum is cooling before the cross prints.
Conversely, a histogram that widens away from the midline after a quiet consolidation can support a later cross. The key is to compare the current histogram sequence with the last failed move at a similar level, not to invent a magic bar count.
Clinic drills use unmarked charts where the MACD panel is shown without the price labels first. Students mark where they would expect a cross, then uncover price. The exercise trains attention on slope rather than on the moment the lines finally meet.
