I usually check the rights of the forex trading. These rights help to know whether the broker is still running. The other thing I check is how the broker of your deposits and withdrawals hurdles. That way you know a good and truly broke. The other thing you should check it spreads and how they are resolved. Fixed spreads really help small business in your account. The other thing I check is communication. Good communication is very efficient. This is feedback from the chat or telephone, email and such.
