I see Ninjatrader listed on the platforms you can use IQfeed data with but can I use Ninjatrader as the broker and Philip Capital as the clearing?

Update: I think I solved my own question. Ninjabrokerage is listed in another location on their site.

Just for your information, you can use IQfeed as your data connection, and open a second connection to ANY broker.
both are independant.

While many people use one connection that both holds the data and the broker,
it is possible to have two connections, one for the data and the other for the trading

The advantage of IQfeed is that you can also have your own stuff talking to the connection
outside of NT or your trading platform (provided you have an API development license)

Absolutely.
