data2 and data3 problems

[ianwaugh@xxxxxxxxxxxxxxxxxxx (Ian Waugh)]

I have a little system which uses 5 min (data1) and 30 min (data2) bars of 
the same data which works fine. However, when I use that same data to add 
daily bars - data3 - to the chart, the system result change. data3 is not 
used  - even mentioned! - in the system code, the mere process of adding 
it to the charts changes the system results.

I'm using ascii data and have to set the date range and session times 
manually each time I insert price data. I've triple checked that all three 
data sets are set to the same values.

Has anyone come across this before? Any solutions?

Cheers,
Ian
