Thanks Seong,

I have a question. Would you say the quantopian format is more supported than zipline? I'm finding it a little difficult understanding how to transform code in quantopian to zipline.

I think there are more people writing in algos in Quantopian than Zipline, but the Zipline community is more technically adept.
