Same problem here! What's going on?!

any idea of when this will get resolved?

any chance we get caught up today on data?

The happened to the data ??? !!!! backtest range locked to last week on the 5th??? any news from the Q team?

Thank you for your patience everyone. There are issues with getting the backtest date up to the current date.

The problem stemmed from our move to Python 3 and some internal date checking. We now check both the Python 2 and the Python 3 servers when figuring out the backtest maximum day. Unfortunately, the Python 3 servers were (erroneously) not updating and stuck on 11/5. That is why it updated to 11/8 (which was when we deployed only Python 2) but then began looking also at the Python 3 servers, which were stuck on 11/5, and took the minimum of those dates.

Probably too much information but a fix is in the works. Waiting for all the servers to cycle. No definite ETA but should be soon.

Sorry for the inconvenience.

UPDATE 2:23 EST Fixed. Latest backtest date is now 11/11. If you still see an older date, try refreshing your browser page. That should fix it. Again, sorry for the inconvenience.
