Does ZipLine in GitHub reflect latest code changes of Quantopian?

Hi,

I have copied some samples from Quantopian, and found at that there are difference in the syntax used. For instance what is on GitHub is called self.symbol and on the website here is is self.STK. In GitHub I miss some features which Quantopian seem to have. Is it true there is a difference in source code, and if yes, how to get hold of the latest so that I can copy-paste my trials back to Quantopian?

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])?

Hi Fawce,

I removed that introducion because I believed it was off-topic and not related to my question. I did post all information in this thread:
https://www.quantopian.com/posts/interesting-stuff-from-a-microsoft-developer-regarding-python-development

Feel free to post any help questions there. Although I believe just downloading and installing would be sufficient.

I hope you can share an update soon, now I am coding things like .notational and .STK or .stocks next to the algorithm.py library in zipline.
