Description:
CMOabsav

Formula Parameters:

• Length1 : 5
• Length2 : 10
• Length3 : 20
• TopBand : 70
• LowBand : 20

Notes:
This indicator plots the absolute value of CMO averaged over three different lengths. This indicator plots a classical-looking oscillator, which is really an averaged value based on three different periods.
