Pre-market scanners for a past day?

Hello,

I want to simulate a day in the past and am using ThinkorSwim OnDemand

ThinkorSwim has the OnDemand, but it doesn't have market scanners for a given day in the past. any suggestion where i can get market scanners for a particular day in the past? i'm just looking for pre-market gap uppers and downers (at 9.30 EST) for a GIVEN day in the PAST.

thanks
