This MACD/Histogram indicator helps me to identify divergences and crosses without much effort.
The MACD line is green during a positive cross, and red during a negative.
My favourite feature is the following: when the histogram changes direction, the histogram bars become yellow, which should help you locate divergences without straining yourself.
Example: Upticking (Green) histogram begins to downtick, turns Yellow. Downticking (Red) histogram begins to uptick, turns Yellow as well.
