How do I write a formula that allows me to count the number of times in a row a condition has passed.
Cum(If(Fml("ROC total system buy")=1,1,0)) this is what I came up with but it does not reset to zero once the condition no longer passes.

I read a post on count but can not get the syntax right to get the formula to work.

Cum(If(Fml("ROC total system buy")=1,1,0)

start:= fml("ROC total system buy")=1

stop:= fml("ROC total system buy")=0

count:= if(prev=0, if(start, 1, 0), if(stop, 0, prev))
count
So what I want in english is a line that moves up one for every time the FML is true, but once it is false the count resets to zero and will not move up again until the FML is true again.

Thanks Mark

Below is an example of one of a number of ways to code what you are chasing.

Buy:=Fml("ROC total system buy");
Event:=Buy;
Count:=Cum(Event);
Reset:=Buy=0 AND Alert(Buy<>0,2);
Counter:=Count-ValueWhen(1,Reset,Count);
Counter
