At the moment I'm on a basic one second refresh across all charts (set via preferences > Intraday)...
All my charts use the same piece of AFL (insert linked into each chart)... I like the same functionality in each chart. I will have to think about adjusting the refresh times across charts. Not sure how I'd work that right now... I'm still struggling with RequestTimedRefresh() vs the preferences>intraday setting... you must know Herman.... which one takes precedence...?
