Custom Formula Collection

The Detrended Price Oscillator (DPO) is an indicator that attempts to eliminate the trend in prices. Detrended prices allow you to more easily identify cycles and overbought/oversold levels. Here is the MetaStock custom formula for the DPO:

Close-Ref( Mov(Close, X, Simple ), T)

***where X is the number of Time Periods for the Oscillator and T = X / 2 + 1.

For example, a 20 period DPO would be:

X = 20
T = (20/2 + 1) = 11
Close-Ref( Mov(Close, 20, Simple),11)
