Ninjatrader Broker

Hi so i am uk based, and am struggling getting on with interactive brokers as it does not supply historic tick data to the ninjatrader platform. So basically if i log on i will only get tick data from that point, rather than the hours before that.
Since Ninjatrader is not FCA regulated how bad is this for me to use them as a broker even though i am in the UK. Is it a really bad idea?

I used Kenetick data with Ninjatrader, and FXCM as a broker.
Its not cheap, but I dont believe in getting something for nothing.

Why don't you consider changing to a different broker? Or is there anything specifics about ninjatrader?

I assume that people in the UK have a problem choosing a broker.
