Sidney,
I´m in a little hurry so I just have had a chance to glance over your email.
I´m a trader as well and thus sometimes have a hard time figuring out a
code that others can program on the fly.
As to questin number three, consider sum() and cum() functions.
The main difference between them is basically that in sum() function you
have to specify the range of bars or else it should count. Cum() basically
counts all occurrences by default, if not specified otherwhise.
As to resetting a counter, I´ll resend the amswers to my response from
Dimitris and Tomasz.
Again, I´m not a good programmer either but if I can somehow be of
assistance - let me (and the others) know.
Cheers
Markus
