Numero, It’s right that forex investments offer potential profits but at the same time, also have downside risk. Sometimes, you may lose more than the value of your transaction when trading on margin. But if you already have been in the market for some time and have learnt risk management, things can get easier for you. My first leverage ratio was 1:5 with oanda. I got an idea about using it and in my next trade, I increased the ratio to 1:50. It turned out to be a profitable trade later. Had I not taken the risk, I would have not made that much.
For a new trader my advice would be to use lower leverages. Or if you really want to get a hand on higher leverage then try with small deposit amounts. Open an account with a broker that has a very low minimum balance requirement like Degiro, no min balance required, or Fxview (Euro 5). This will give you confidence for switching on to higher amounts with higher leverages.
