Hi J,
Quantopian uses algo scripts, which are run via a subclass of zipline.algorithm.TradingAlgorithm. We have not released the Quantopian script host to the zipline project, so you can't use the special builtins we added to Quantopian such as the sid function, and the structure of the script is independent of the zipline base class.
When you write an algorithm in zipline, you subclass TradingAlgorithm directly. Quantopian doesn't currently support direct deployment of TradingAlgorithm subclasses. So today, it is not easy to move algorithm code between zipline and Quantopian.
As both the zipline and Quantopian communities have gathered steam, this gap has become more acute. We're now considering open sourcing the script host so that zipline developers could work with Quantopian script and then run the identical code on Quantopian. Would that work for you?
thanks for the question,
fawce
p.s.
In an earlier version of your answer you had a bunch of interesting links related to a visual studio setup for python development. I didn't have a chance to follow them, and I was curious to learn more about the setup. Could you repost? Or email me directly ([email protected])?
