I also hasbeen get calling from some broker of forex, they explain the detail trading product and the benefits of their trading platform. Many of them just offer margin trading. Trading can be good way to earn extra income, and for beginner trader is beter avoid margin trading and more focus on spot trading. We should be know the risk first and then we can create risk management to minimize it.
Well if you are a newbie, dont get into margin trading. You better must start with good skills and demo trading. Learn better and only then you can have good results and future.
