you should maybe have left it the way I wrote it :)
BarsSince(Buy=1) means you assign the value of 1 to variable buy
it should be Buy==1 meaning check if equal to 1.
By default just writing Buy assigns 1 to the value, so it means check
when Buy had the value 1
so
BarsSince(Buy) is the same as BarsSince(Buy==1)
