Hi,

my algorithm uses the FundamentalUniverseSelectionModel.

I ran it for two months in live trading now and compared the trades to my backtest during the same period. Turns out 90% different symbols were selected. My algorithm selects based on trends in fundamental data. E.g. as soon as a company has lower earnings than in the period before, it drops out of the universe. So a closing trade should happen directly after market open.

According to your docs, fundamental data arrives between 6-7 am and is then processed.

The backtest, is running the universe selection process at 00:00 (midnight). I wonder, if my live algorithm is running the universe selection at midnight as well, or if it is triggered dynamically, whenever new data is ready (using Morningstar data).

My suspicion is, that the live trading universe selection uses data from the day before, but the backtest selects the newest data from the current day.

I appreciate your help.

Best regards,

David
