I really want to give Quantopian a go. I see great things apparently achieved by others. I admire the software and the coding. I have looked at Alphalens, Pyfolio and Zipline on Github. I have even downloaded some of it to play with in the past.
I really, really would like to get into this. To play it seriously, to help discover some alpha, to make some submissions to the contest but Alphalens and even Thomas Wiecki's cut down and more easily understandable version are simply unusable during US opening hours.
I had more luck this morning in Europe but had to go out for the day.
What are other people doing? What are their experiences? Are you suffering the same frustrations? How are you getting around it?
Or are you mostly relying on the back tester where at least you can set a few back tests going and come back hours later to see what has happened?
Perhaps some of you are working off line? On your own data?
