Why should we use stop loss because stop loss is the only tool that traders have, forex is nothing but the riskiest business on the planet and to be successful in forex you must minimize your risk and stop loss is the only tool that helps you minimize your risk. and Stop-loss is the most important term in Forex. Because reduction of reductions always saves your account. If you don't set a reduction for reductions every time you make a big reduction. So in my opinion we first need to know which position is right to set the stop reduction. Most reduction investor positions stop them very close to their order. so they can't make big benefits. At any time your business can exchange from full benefits to full reductions and that is why we need to stop reducing.
