Hello Frank,
the ROC is not smoothed in the orignal OddBall. It is simply the
percent change from one close (of Advancing Issues) to another 7 bars
later.
go to Functions and open the RateofChange function to review the
calculations. here it is:
{*******************************************************************
Description: Rate of Change
Provided By: Omega Research, Inc. (c) Copyright 1999
********************************************************************}
Inputs: Price(NumericSeries), Length(NumericSimple);
If Price[Length] <> 0 Then
RateOfChange = (Price / Price[Length] - 1) * 100
Else
RateOfChange = 0 ;
Best regards,
Jim Johnson mailto:jejohn@xxxxxxxxxxx
