Broker / Cross Trading / Futures

[thierry_dieteric]

Hello,
I don't understand the table : "Bookmap®-Compatible Market Data Providers"
And the more I speak with the support, the less I understand. I think it is necessary to clarify.
What I only want is to trade Futures Nasdaq, Dow Jones from Bookmap.
From the table, I understand the best recommanded choice is Ninja Trader with Rithmic to have full depth of market.
But ... it seems not so easy ...
I understood CrossTrading : one connexion to the broker, and one connexion to Rithmic or DxFeed for the data. Bookmap use both.
But, do I need to buy 2 access to the data ? One from Rithmic/DxFeed and one from Ninja to access trading ?
What I have to buy if I want to trade CME Futures directly from Bookmap ?
Thanks a lot in advance.
