In my opinion, double loss with double profit is true, traders must understand this fact about Forex trading. There should be no attempt to double our lot because it produces more profits or double profits. Risk must be controlled at all times with a good MM policy. So there is no problem trading. and my opinion is equivalent to if you use a small stack then you win or lose small too, but if you use a bigger heap then you win or lose bigger too. so it depends on your cash management. and you want to have an honest strategy to support it so that if your capital increases then you will add the heap that you use and multiply it for double profit
