Hi Anthony,
I pasted your example into the Analysis
window and the exploration results make a good example of the problem. Notehow
the last column of the first set, representing Count1 only resets to
zero for those bars where the buy condition is true, then picks up where it
left off. I want it to start over after each buy, like the second set
which I've pasted below in blue.

Hello,Not sure what you are looking to
do.CondCount=Cum(V>10000);Buy=C>MA(C,28);Sell=C <
MA(C,28);Count1=IIf(Buy,0,CondCount);Filter=1;AddColumn(Count1,"");Esteban
