Paper Trading a day in the past on Interactive Brokers

Hello,

Can I pick a day in the past, then scan the biggest pre-market movers for that day and paper trade them?

I have a live and a paper accnt in IB

thanks!

 

No.

 

Nope. This, and all sorts of other reasons, is why I built my own everything.

 

Why wouldn't you build a backtester on top of their data?
