This is a very important one and can't believe that I didn't mentioned this one a lot sooner. You see, FB, Twitter, and I think Gmail have strong security. But all the brokers I can think of, don't have them. For some people that trade for a living, their account balance is pretty much all of their money and we know that access by an intruder can cause that trader to pretty much lose it all with the amount of leverage that FXCM offers.
So here is a good measure that would be great if Protrader users can implement within the settings:
Whenever someone tries to access an account from an unfamiliar IP address, then a password is sent via text that always varies. An additional benefit to this is that the real account owner will get a notification when someone tries.
