Hi! I am using IQFeed. Hmm, but why these differences? Is it because of the data provider or AB? I would guess data provider....
I also realized that total volume numbers I get, are diffeerent from the reported numbers. For example last Friday, CSCO is reported to have a total volume of 66,935,323. While these 2 lines: Bars_so_far_today = 1 + BarsSince( Day() != Ref(Day(), -1)); Value = Sum(Volume, Bars_so_far_today); Gives me 61,516,544!!?? Anything wrong with the code, or why do I get different numbers? Thanks, Jorgen --- In [email protected], "Jerry Gress" <pleasenospample...@...> wrote: > > Hello, > > What data source are you using?
