Thats right! some forex brokers do not support scalping system due to the configuration of their back office system. So if scalping is our trading style then we must check before we open an account with our broker.Scalping in forex can b quite dangerous cos when we are making use of a small time frame like say 5 mins or 15mins they signals come more often and wehn the market is bad, the signals are bad and we can end up loosing more than we expected. SO we should be careful and adopt a safer trading style.
