Stop Loss Orders: If you dont use stop loss orders, you are leaving yourself at the mercy of the markets. A dangerous proposition with unlimited downside risk! Stop loss orders are critical to your trading survival. If the market moves against your position, stop loss orders are used to limit losses. The traditional stop loss order does just that. It stops losses by closing out an open position that is losing money.
If you are short, your stop loss order would be to buy but at a higher price than the current market price. Stop loss orders are on the other side of the take profit orders but in the same direction. If you are long, your stop loss order would be to sell but at a lower price than the current market price.
Trailing Stop Loss Orders: The trailing stop order adjusts the order rate as the market price moves but only in the direction of your trade. A trailing stop loss order is a stop loss order that you set at a fixed number of pips from your entry rate.
Suppose you are long on EUR/GBP at 1.2654. You set the trailing stop loss at 30 pips. The stop order will become active at (1.2654-30=) 1.2624 initially. As the market moves higher, the trailing stop loss order continues to adjust itself higher. Suppose the EUR/USD rate goes up to 1.2674, the stop adjusts itself. Now the stop order will become active at 1.244.
When the market puts in the top, your trailing stop will be 30 pips below the top. If the market ever goes down by 30 pips, the trailing stop loss order will be triggered and your open position closed. So in our example, you are long at 1.2654. You set the trailing stop loss at 30 pips and it became active at 1.2624.
Suppose the market never ticks up and instead the market goes straight down. You will be stopped out at 1.2624. Instead suppose the market first rises to 1.2664. Then the market declines 40 pips. Your trailing stop loss order will first rise to (1.2664-30=) 1.2634. It is at 1.2634 that you would be stopped out now.
You must have heard the saying: Cut your losses and let your winners run. A trailing stop loss order allows you to do just that. The idea is that when you have a winning trade on, you wait for the market to stage for a reversal and take you out of your trade by using the trailing stop loss order instead of picking the right level to exit on your own.
Using stop loss orders is critical in trading as it helps you in money and risk management. Trading without the stop loss orders is foolish! Never ever do that! So the key to successful trading is to cut losing positions quickly and let winning positions run. This is what a trailing stop loss order does. It helps your winners run and cuts your losses.
