Previously i have no idea about stop-loss. And then i loss a lot of money. Now i become conscious that if i use stop-loss method, then in all probability overcome that loss. Now i use stop-loss and target profit both on my trading. And doing well in the market. Stop-loss basically minimize the amount of risks or losses in forex trading. But if you invest civilized amount of capital, then its your wish whether you use stop-loss or not. It is not that much necessary.
