Broker

Hello, I've being using Saxo Trader Broker for 3 or 4 years now, as its charting software is quite good. However, I am wanting to change things up and buy ensign charting software, and also looking for another broker. I remember Patrick mentioning he was with Interactive Brokers previously, but has recently changed over. Would it please be possible to know which Broker Patrick uses, and if that's not possible, does he recommend Interactive Brokers, even after he's left them? Also, does he still use ensign charting software too? Thank you, Chris :)
