Hi Michael, I found this same formula and put it into a .AFL file. It worked fine. My first thought, on seeing your post, was to ask if the Intraday data you are looking at is in the FOREX market. If so, no volume data is provided and therefore the myobv variable won't have any value. If it's Intraday data that contains volume data, I don't know the answer. Bill

Any idea why this happen? Thanks, Michael Please note that this group is for discussion between users only.
