Completely confused

Last question, which is probably somewhere in the answer you already gave, but can I find which platform works with which broker through the broker, through the platform or through both?

Either, or both.

If you go to the broker's website, they will tell you. If you go to the platform's website, they will also tell you.

They want you to know. It can be a selling point for them, if you like a particular platform, or a particular broker.

Bob.
