Say I am incrementing a variablethat
counts the number of trades of volume > 10000 using the cum function.
count = cum(v > 10000)
;But I don't want a count from the beginning of the data set. I
want the count from an event.
I've thought of several ways to
accomplish this in principle, but I always run up against the same issue no
matter what scheme I devise. The reset doesn't stick, it's only good while
the condition that causes it is true. Here 's an example.
Reset the value of the variable and start
the count again after each buy, like in vb.
count = iif(buy, 0, count)<FONT
face="MS Sans Serif" size=2> ;
The problem I run into here isthat I
can't reference the the variable count in the formula if it hasn't
already been assigned. Therefore with the formula above count = 0
only on the bar that buy is true. The next bar it reverts to whatever it was
previously assigned. This doesn't give the effect of resetting.
I've given this a lot of thought
and tried to work around it a number of ways. I'm stumped. Any help is greatly
appreciated.
