Today is a Saturday (September 9th) and it seems that the Quantopian backtester will not let me run a backtest ending with yesterday's data (9/9). Ideally I'd like to access today's data after the market closes. Does the prior trading day's data only become available at a certain time on the next trading day? Is there any way to alleviate this? Thanks!
you'll have to wait until Monday to see how your strategy did in Friday's bloodbath
only workaround is to paper trade a live algorithm, then you can just check that but that won't work retroactively of course.
In previous weeks Friday pricing data was available on Saturday. Is the "bloodbath" the reason it wasn't this week?
Durring the week backtests can be done the following day at least by 8am Eastern with previous day's data. If my memory is correct, it seems to me I've run backtests on the weekend with Friday's data.
Today, Saturday October 29th, it looks like this has repeated. No Friday data. On all the Saturdays since this problem last occurred on September 9th we've had Friday data.
I wonder what today has in common with September 9th?
