Anyone else having issues with building/backtesting? I haven't been able to complete a build for roughly 30 minutes, but it was working fine before then. Cheers!

Build timeout
Roman Gutin | April 2020
Anyone else having issues with building/backtesting? I haven't been able to complete a build for roughly 30 minutes, but it was working fine before then. Cheers!
Hi Narayanan,
Thank you for your question. Basically, there are two reasons led to this issue: 1) it should be stock.Symbol (not stock.symbol) in line 24; 2) we cannot get the elements in _Coarse_filltered_stocks_ using for stock in Coarse_filtered_stocks when Coarse_filtered_stocks is not a list. In Python3, filter() returns an Iterator instead of a List, so we recommend you not use filter(). In the following backtest, please let me show you another way to achieve this.
Based on your idea, I directly rewrite your backtest. The results show that there are 5476 stocks in Coarse Universe and 1847 stocks in Fine Universe (i.e. 1847 stocks in NYSE), which is reasonable. I hope this will solve your problem. For more information on Universe Selection, please see this page. We look forward to your good news!

I am experiencing the same issue around the same time frame as you.

=( Sorry guys. Tweet @Pusher and maybe they'll wake up and fix their service.
We're working on an open-source replacement right now.
