I am trying to write a code to calculate the total up move on a series of back to back up bars (or total down move on a series of back to back down bars...(this is only part of the code because I have to take into consideration the case when ROC(C,1,$)=0 which I have done in part of a code thats not below...)

A:= BarsSince(ROC(C,1,$)>0);

B:= BarsSince(ROC(C,1,$)<0);

If(ROC(C,1,$)<0,

   If(Ref(ROC(C,1,$),-1)>0,ROC(C,1,$), ROC(C,A,$)),

   If(Ref(ROC(C,1,$),-1)<0,ROC(C,1,$),ROC(C,B ,$)))

but I keep in getting an error that I can only use a constant inside the ROC function.

In other words if  I have 5 back to back up bars then I would find 5 by
BarsSince(ROC(C,1,$)<0)-->which should give you 5
Then I would want to calculate
ROC(C,BarsSince(ROC(C,1,$)<0,$)
to find the total up move from the 5th up bar to the very start of the up move of the 5 series up bars. but metastock is not allowing me to put the barssince function inside of Roc or Ref function

So what do I do? How can I go around this? Any ideas would be very appreciated?

Thank you

Hi Arash,

Welcome to the Forum.

As it seems you have most of the code sorted out for what I think you are trying to achieve, I wont distract you with other possibilities, except to suggest you download the free forum.dll from the files section as this contains a variable ROC indicator where the lookback periods does not have to be a static integer value.


Hope this helps.

Thank you for your help. Thats exactly what I needed...I guess I was not the only person in need of a variable ROC, LOL

Thank you!
