I use IB for my broker and have esig, but we all know IB's charting lacks much to be desired, so for a backup i got quotetracker, its FREE for only 2 days backfill, but if i just open a small accuont with TD AMERITRADE, can i just use the IB data and just get a reg code from TD? and have free backfill for more than 2 days instead of the regular 7$ a month? thanks
