My only live market broker is advertising on this site, i.e. IC markets. I have found no fault with their monetary transactions to and from my account, executed on same day, as all client money is held separately in major AUD banks. They cannot access your capital. And you get a daily e-mail showing your trades outcomes and updates of funds available. My only gripe is that there is often a long holdup if you need to use their chat line, but when linked up, the person is very competent unlike some other broker reps.
If PM demand heaps of identification documents from you to open an account, I would suggest they’re kosher regulated - and they have been in business for many years.
