Backtest Error
Something went wrong starting a full backtest.
I am not sure if the other have the same problem.
I get quite often error by starting the backtest
This may be different because you said "full backtest". Varies but often "Execution timeout" on start here in under 15 seconds. Average retires ~4 maybe. Even if the backtest is for only a few days. There's a very tight timeout of some sort.
If you change your start date to a few trading days before end for less work by pipeline, any difference?
As a result of the "great improvement" since Sept 2018 for each bascktest run , I get about 10 'Error Execution timeout'.
In the previous 4 years, I didn't even know that such an error existed.
Very often I cannot save the changed settings (the “Save” button is not active).
Right now “Save” only responds to code changes but not other settings.
@Blue:
...If you change your start date to a few trading days before end for less work by pipeline...
What do you mean here? A concrect example maybe ?
The error you're addressing is -- "Something went wrong". That might have to do with pipeline, we don't know, but there's a chance.
I'm assuming your algorithm is set to run for the last 2 years or so, some number of years, and just suggesting you run a test by changing the start date, like, for example, to 01/02/2019, since the most recent date available right now is 01/04/2019. Thus covering only a few days.
Pipeline loads in chunks, some number of months at a time. A backtest of just the last few days has less pipeline work to do.
If it makes a difference, then I would try adding more and more time.
Ok, now I understand what you mean. But the errors I got have definitely little to do with what you said since the errors I got is just right after I clicked the backtest button. If I tried many times or after a while, it works again. I guess the Q has reduced the power of the server or has set some limitations. If "too many peoples" are doing the backtest, someone will get this error. But this is just my guess
Hi all,
We recently diagnosed an issue that was causing timeouts during the code validation step. We are now working on a fix.
Thanks for flagging, everyone.
