Rahul,
The formula that you submitted works but the output is not the same
as the canned Metastock indicator. This one is:
{Stochastics}
{byRahul Mathur}
{EquisMetastock 4-2-'04}
{For full stochastics using three periods}
Period1 := Input("Time Period1", 1, 100, 12);
Period2 := Input("Time Period2", 1, 100, 3);
Period3 := Input("Time Period3", 1, 100, 3);
a:=Sum(HHV(H ,Period1)-LLV(L,Period1),Period2);
b:=Sum(C-LLV(L,Period1),Period2);
Kfull:=(b/a)*100;
Dfull:=Mov(Kfull,Period3,S);
Kfull;Dfull
The difference, although suttle, involves summing the Kfast rather
than using a moving average. Metastock uses summing. Again, great
work!
