cheapest backfill data for qt?

Hi im sorry if this is in the wrong forum.

I have qt but as you all know it doesnt come with any backfilled daily charts. Where can i purchase the cheapest backfill data for qt? I have been searching but not found any solid results.

thanks a lot for your help

 

did you check supported market feed section?

how about TD ameritrade?

 

i have mb and they dont support backfill with qt.

is there anywhere i can just buy the data?

 

iq feed. td ameritrade-just open an account. can't be any cheaper

 

ok thanks
