Actually if you can trade with a platform on Windows based computer, it's possible to do it with MAC.
There is a mac version of investor r/t from www.linnsoft.com that will take data from Interactive Brokers and send fx orders to them. FX leverage from IB is only available outside the US.
I guess its paid software, better to use PC simulations on Mac, I think they are fast and stable enough, if you don't practice scalping of course.
Yes that's why I was asking. Anyway some brokers offer incorporated parallels software in MT4 (like Tickmill) or provide instructions on how to launch it using Wine simulator (Hotforex) Not a problem though stability problem remains a point of debate.
