whether zipline supports future trading(SHORTING)

Dear Zipline Maintainers,

whether zipline supports future trading backtest？ It seems that I can order_target_percent to -0.5.

While I am not sure that the final perf will be correct?

Before I tell you about my issue, let me describe my environment:
