I learned today that you have to put a stop loss, because I trade without a stop loss for a while and the market crosses the line and makes me lose big, but if I put a stop loss I will not arrive at this situation and I cut it before they become more big and that's business. In the business of loss and profit both are available. So it makes a better profit to do a loss analysis. And understand the market. Take the time to make a decision to buy or sell a currency. I think there are people who follow this role, fortunately they have to come, but some losses can occur.
