I think Paul's suggestion not to run so many symbols is a good one and I can pare down the list for many tests, but there are some for which I need to run over 20,000.
How do I go about putting the Premium data into native AB format? This database will be used for historical backtesting and does not need to be updated, or not often, so it would make sense to move this over to native AB format. Is this a simple process?
Thanks.
