Cumulative delta divergence is often a sign that a move is going to end.

Today there was a great example. The Fed Minutes were going to be released today. The stock market was rallying, but once we hit the high, the market went sideways and made a run back to the high of day but didn't quite get there, however cumulative delta kept going higher and higher. This was a sign of absorption and more importantly supply being distributed. Once day traders realized that price was going higher they all started to bail out of their positions and the market then dropped about 1618 points in about 10 minutes because the last thing they want to do is hold that position through the FED minutes release. Talk about being long and wrong.
