I found a way. I added a for loop around the buy and that works. I don't understand why I had to do that.
aDate = DateNum(); for (a=0; a < BarCount; a++) { Buy[a] = ifDate(aDate[a]); } --- In amibroker@yahoogroups.com, "Barry Scarborough" <[EMAIL PROTECTED]> wrote: > > I am trying to create a file that will show trades on dates from an > input file.
