Hi Kalenzo,

I found that also. But it is not clear to me.
'WPR' probably means : 'Williams Percentage Range" . That is an indicator, once invented by Larry Williams, which is indeed similar to the formula for Stofast and Stoslow.

But the meaning of the line " price1 = ....... " is completely unclear to me.
What means :


a) StepMAmax, StepMAmin, Stepmin
b) Kwatr
c) Watr
d) Stepmax

and how is he doing a calculation there ?
Kwatr seems to be equal to 1 in the MT4 indicator and periodWatr = 10.
But for the rest ?

Trading was very difficult today. Eurusd went to look everywhere.
