Aroon Histogram + CMO [ChuckBanger]

This is a combination of Aroon and Chande Momentum Oscillator . I made a histogram of Aroon , aqua line is Chande Momentum and the orange line are a simple moving average of Chande Momentum as a signal line.

One strategy you can use this for is to buy or sell when the signal line crosses the CM line or you can buy and sell when CM line is highest or lowest

You should also study how the indicators work separately:
