Histogram bars that arrive late
A tall histogram bar can show up after the price swing has already tired. The Evening Histogram Workshop spends its middle hour on that lag.
The histogram is the distance between the MACD line and the signal line. When that distance grows, the bar grows. Nothing in that sentence says the price is still making new ground. The bar is a comment on two averages, and averages speak after the fact.
In the workshop we sort bars into three piles, using a practice sheet rather than anyone’s live market. The first pile is bars that expand while price is still pushing. The second is bars that shrink while price is still pushing — a disagreement worth marking. The third is bars that expand only after price has stopped making new highs or new lows. That third pile is the one people have usually been treating as strength.
A late bar is not useless. It tells you the gap between MACD and signal is still widening even though price has gone quiet. On the desk we treat that as a reason to look harder at the momentum window, not as a reason to add a fresh mark in the direction of the bar. If the ten-bar pace has already flattened, the tall bar is late news.
You can see the lag with a finger. Cover the price panel. Guess, from the histogram alone, whether the latest swing is still underway. Then uncover the price. The workshop evening is built around how often that guess is late. Nobody is scored. The point is to stop hearing “tall” as “early.”
If you already sit with MACD and you only have one evening, come for the histogram. The signal-line work can wait for the desk. The late bar is the mistake we see most often on the charts people bring from home.
