Seems like an important note since probably 90% of my orders execute on ARCA “and the other ECNs.”

Supported market data feeds include Nasdaq TotalView (full depth), Cboe/EDGX (full depth), and NBBO. However, ARCA and other ECNs are not included in dxFeed's market depth data, which may result in order book discrepancies.

Learned today that Omnifeed no longer available on Bookmap. Wonder why?
