Oscillator Pretty Good Oscillator (PGO) by Mark Johnson

I too use Metastock and have downloaded the zip file from Mark Johnson's site. There is a readme.txt file on Metastock but it doesn't contain any Metastock coding of the PGO. It simply gives a few outlines of the TradeStation terminology to assist in converting TS code to MS.
However, the decrypt version code posted by Jim Payne (see below)PGO = (C- Average(C,89))/Xaverage(TrueRange,89) you mention is easily converted to Metastock code as follows:​

​

Or using the Average True Range version -
PGO:= (C-Mov(C,89,S))/ATR(89);
PGO
I have plotted the indicator in Metastock comparing it to the RSI(14) and it is very similar. I ran some tests using the parameters set by Mark Johnson that is, "if indicator > +3.0 then go long
if indicator < -3.0 then go short
if indicator crosses 0.0 then exit and go flat"
and I got very ordinary results on several stocks I tested so I can say I'm not that excited about it.
Hopefully this helps with the MS coding anyway.​
