I have discovered a problem getting data ONLY when I am creating a chart for range bars of more than about 15 days.
I try and create a chart for say 30 days of range bars of 6 points for say YM #F from eSignal and @YM from TS, I only get a few days.
eg, today, I am trying to get a 30 days chart but only get back to 21/12/06 from both data vendors. If I want either tick or minute data, I can get months of data.
Is there something different for range bar data that is doing this?
