Backtests in Date Ranges Where Data Doesn't Exist

Hi All,
Since 2-3 days my algorithms suddenly began to execute very slowly?!
When I click on "Result" I see the percentage goes up slowly.
Has anyone else seen similar problems or it is just me?
Thanks
Nik

Hey Nik! I sent you an email about this - there's a bug if you request data which doesn't exist yet it still checks every single day which slows down the backtest. We're working on this now to process the date ranges more intelligently.

Give us a week and it will be fixed, for now if you select date ranges where all the assets exist it will work quickly :)

Yes, I saw your email. May be this was not the problem:
The ATR which I copied from one of the projects actually stores data - never removes last element of the queue. This lead to alg. consuming close to 1GB of memory (that QC allocates per alg. I guess) and slows down execution.
