Does someone know if there is a difference between those two feeds regarding the quality of the data? Does TOS offer options tickdata?
So does DXFeed (if by "Level 2" you mean the BBO data). In fact, from looking at the genealogy of the two companies, I suspect that DXFeed provides the data for TOS.
My problem is i have an IB account and am using Motivewave and Medvedtrader. I also have an TOS account but don´t want to trade in this account. When daytrading options currently i´m charting with TOS and have to execute the trades on Motivewave or IB directly (booktrader). But i would like to trade on the charts. Using Motivewave or Medvedtrader with IB options data is awfull because of the limitiations. I could subscribe to dxfeed´s OPRA Options data and use them in Motivewave or Medvedtrader. But it´s a little bit annoying because i have to pay for data which i already have with TOS. In TOS i see more than NBBO.
antares, you can use MedvedTrader with Ameritrade data but connect to IB for trading. I just put up market depth for options in ToS, and they are showing BBO (best bid/offer) data from 10 exchanges just like dxFeed does (and you can get it to show in MedvedTrader as well with Ameritrade as data).
I know, i tested it yesterday. But the problem is TOS doesn´t provide backfill for options via api. They offer this only on their platform
In TOS and IB i get 5 to 10 best bid and ask option prices on the DOM. Not only top of book. Does dxfeed offer the same?
