Okay let's say that I have a reasonably good automated strategy that I am ready to go live with. However, I have several other strategies, and also would like to continue tweaking with my original strategy. So I would like to start trading live, while simultaneously keep testing different strategies. And in addition, if another one of my strategies matures enough, I would like to then independently run the new strategy in addition to the old one. So my question is: what would be the best way to do this at IB? Should I (or can I) open up several subaccounts? In that case would I be able to run live, and continue to test on the paper account? And does each subaccount get the 100 live quote streams? Or is the 100 max apply to all subaccounts in aggregate? Would appreciate if anyone has any suggestions or ideas. Thanks.
