Thanks for this. The problem is fixed.
However, I am not able to see the difference b/n this and the old one.
I use EOD data. Is this update for realtime/intra-day date?
What I have been looking for is a way to reduce the time that takes to
convert the TC2005 data to the native database. Normally, I first
dawnload using TC2005. I then start AB and run scan over the whole
databse. I then close AB so that the data is saved in AB native
database. I then restart AB. Change the database to local. Then
continue my backtesting. This whole process takes about 15-20minutes.
