Pretty sad that you don't show any of the ecn trades on SMART backfill after all this time? Having to call up an Island or ARCA chart is very lame, and third party apps like QuoteTracker don't access that data. It needs to be part of SMART. Ameritrade backfill shows this data, you don't want to be shown up by those guys do ya?
Stock, Im certain you've thought of this, but if you have a Ameritrade account, switch data source via Menu button and configure a portfolio for just premarket data. You should be able to get a quote/and or pull up premarket chart. Just make certain not to have same symbol in 2 different data portfolios when market opens proper. Of course IB add backfill, its moot
Yes, I did think of that , but it's a pain in the butt. I don't think you have to worry about duplicate symbols, as backfill is a global setting, only one at a time.
