Hi all,
Facing the problem of using a vriable under HHVbars() function. The error i get is "This variable or expression must contain only constant data".
Specifically i was doing this
r:= PDI(13); m:= MDI(13);
x:= barssince(cross(m,r));
y:= hhvbars(m,x);
(trying to find the maximum mdi value since the last cross of mdi by pdi). But I recived the above error. Probably I can't use 'x' variable within hhvbars. Please help.
Also, is there a way to use loop in metastock (using version 8)? Need it badly.
Thanks

Yes, the HHVBars() expression can only contain constant data; but there are many ways around what you are trying to achieve, I reckon the simplest solution is to download the free forum.dll from the files section. The HHVBars() in this library allows the use of dynamic periods
y:= ExtFml( "Forum.HHVBARS", m, x) ;

Sometimes there is another way to do some calculations, but if your computation truly requires a loop, you can only write and external function in a language which allows loops, or export the required dat to another application (like Excel) do the calculations there and then import the values back into MetaStock.
Hope this helps.
