You cannot export data from Quantopian - it is against their terms of service.

I tried doing this many moons ago by adding the data as request params to fetch_csv and pointing the fetch_csv url to my own API - but Quantopian shut me down pretty quick (so quick I was actually impressed).

If it is small amounts of data, you can just print it out into logs and just copy that into your own systems for further processing.

I ended up installing zipline on my own servers and sourcing my own data so I could run the algo the way I needed to without any limitations.

Thanks a lot! I guess I will learn to do the same.

By the way, do you use zipline with ipython notebook? Do you think this way is more friendly to newbies? Do you know where I can find more example codes of using zipline with ipython notebook?

thanks again

I didn't use it with ipython notebook.

If you want to use zipline I would say it is definitely a big investment - don't do it unless you are willing to spend a lot of time/money on building the infrastructure.

i see, thanks for your advice. What if my purpose is only to process my data with all kinds of technical indicators? What would be the most newbie friendly approach?

Quantopian is more of an advanced platform that allows you to code pretty much anything - it is very powerful but does require coding. I suggest trying to code your indicators up in Quantopian if you want good backtesting.

If you want something more friendly, try the indicators on tradingview.com - you can code up systems on there too, but only for 1 security at a time (it is chart based) and you don't have access to things like fundamental data.
