Paper trading need help

I am doing test with quantopian paper trading. How is the commission calculated ?
If IB account is used, how is the commission calculated?Ib routing
The link shows a $0.09 per 100 shares ? Is that even true?

The default is $0.0075 per share and $1 minimum cost per order, see: https://www.quantopian.com/help#ide-commission
I think you're looking at the wrong page for IB's commissions, look here: https://www.interactivebrokers.com/en/index.php?f=1590&p=stocks1#north-america
You can set the commission however you'd like by adding the following to the initialize section

    set_commission(commission.PerShare(cost=0.005, min_trade_cost=1))
