Anyone using Quantopian to IB with short selling?

Is anyone out there using Quantopian platform connected to IB for short selling?

If you are, I want to make sure before I turn my algo on that I am accounting for the correct IB commissions with the below:

set_slippage(slippage.FixedSlippage(spread=.02))
set_commission(commission.PerShare(cost=0.005, min_trade_cost=1))

Is there anything else you have encountered that I should/need to be aware of? My algorithm trades long/short VXX.

Thanks!

Hi Tyler,

The commissions you will incur from IB depend on the setup you chose when you opened your account. From your code above it looks like you are correctly accounting for the fixed rate pricing.

I would strongly suggest that you paper trade your algorithm before deploying it to a real money account. You can find instructions on how to create an IB demo account in our Live Trading FAQ.
