yeh stop placing is a very important factor that most traders need to learn and practice very well in trading Demo accounts. Because there is no sure way to do it, most people follow the way they feel better for them. I use pivot points and support the resistance method for this. and Stop loss is needed in risky Forex business. Therefore we must trade with good money management. If we don't set stop loss orders, we can lose big capital. Several times we got immediate losses due to inaccurate arrangements. So in this case the market, the best analysis is needed.
