10.8 Chande Momentum Oscillator

The Chande Momentum Oscillator (CMO) by Tushar Chande is a variation on the RSI (see Relative Strength Index) using an SMA (see Simple Moving Average) and on a scale between -100 and +100.

CMO = 100 * ---------------------------------
            SMA[N] of  abs(close - prev close)

The formula can also be written in the style of the RSI, with U=close-prev on an up day, and D=prev-close on a down day.

                   SMA[N] of U + SMA[N] of D
