Dear All, When testing speed of my local zipline environment vs Quantopian environment, I found local zipline environment 35 times faster than Q server. Working example: Dual Moving Average Cross-Over; Conclusions; Data Bundles. When defining handle_data, we need to pass it the context variable from above and data to work with. Why bother including the 'problem' entry if the algorithm is an exact eigensolver?

This is where most logic should be, before_trading_start : callable[(context, data) -> None], optional, Function that is called before any bars have been processed each, analyze : callable[(context, DataFrame) -> None], optional, Function that is called at the end of the backtest. # use the end_session as the date for symbol->sid resolution. Notes ----- These values will appear in the performance packets and the performance dataframe passed to ``analyze`` and returned from :func:`~zipline.run_algorithm`. If the user passed trading_calendar explicitly, make sure, # it matches their sim_params. The code is overly documented, since I do not really have experience with Zipline and so this may also serve as a reference for future programming adventures. There is already a tutorial detailing how to run the buyapple.py example that comes with Zipline.
