hi @/all. We've just released version 1.3.0 of Zipline. Highlights of this release include:
This is likely last minor release in the Zipline 1.x series. The next Zipline release will include preliminary support for international markets, which we expect to require a small number of breaking changes. As such, the next release will most likely be Zipline 2.0.

Hello.. I've installed zipline, but when I try to execute some script with run_algorithm it takes me a warning and the result of backtest is a zero dataframe (i mean, every column is filled with zeros).
The warning is:
C:\Python36\lib\site-packages\empyrical\stats.py:704: RuntimeWarning: invalid value encountered in true_divide
C:\Python36\lib\site-packages\empyrical\stats.py:790: RuntimeWarning: invalid value encountered in true_divide
np.divide(average_annual_return, annualized_downside_risk, out=out)
I'm using python 3.6, numpy 1.15.4 and pandas 0.22 (current versions).

A session represents a contiguous set of minutes, do we need two sessions in one day?
multi-session in one day, then there will be

Positionsare aggregated on
assetid and values like
cost_basisare taken as a weighted average and
last_transaction_dateis updated after additional transactions. Anyone know if there is a version of Zipline that is tax-conscious?
