Live Trading Questions

Hi Everyone,

Interactive Brokers charges some fee for live trade data unless you generates a certain amount of commission fee each month.

My first question is that whether Quantopian requests data from IB in our account or Quantopian uses its own external data
source to calculate the trading decisions.

If the latter were the case, I could theoretically turn off the data subscription to save some money and have no effect on the
performance of the algorithm. Please comment on that thought.

My second question is that I have set a certain commission fee in backtesting the algorithm. Do I need to remove it when I deploy
it for live trading.. I don't think it should have any effect. I am just trying to be sure.

Best,

Nyan

Hi Nyan Paing,

We don't use (or require) IB market data to run your algorithm against your IB account. We subscribe to a pricing feed from Nanex which drives live trading. I believe IB will give you a warning about 'blind trading' if you disable your market data through them, but I believe it is possible to dismiss that warning (it would be best to confirm this directly with IB however).

To your second question the commissions and slippage setting used in backtest or Quantopian paper trading for your algo are simply ignored when the algo is deployed against an IB account - you can comment them out, but you don't actually have to change the code at all.

Please keep the questions coming and let us know how you are getting on!
Best wishes, Jess
