search MACD histigram maximum and minimum
the minimum histogram predicts the long MACD crossover with a lead time of a few days. we need to know a few days in advance if the MACD will cross.
Richard Brimhall commented
The extreems of the histigram are a leading indicator of the MACD crossover. It can indicate a possible buy or sell signal a few days before the MACD actually crosses. It is a leading indicatror which should be available in the Protrader Uniserch set.
