What is the PGD_Slope indicator?

[Import]

I could not find any documentation of the PGD_slope indicator. Could you send me some basic info on it?

PGD_Slope is a calculation of the slope (rise over run) of a stock. It's called PGD_Slope because it is the calculation that Paul Grems Duncan uses in his research.

The formula is:

EMA1:= EMA(C, N);
SLOPE1: ROR(EMA1, 2);

So it is basically the slope of the N period EMA between current and previous bar.
