Trailing stop order example
You think the Germany 30 is entering into a bull market, so you decide to buy it at 12,555, with a trailing stop at 12,540. This allows the Germany 30 to move 15 points against you before the stop closes you out.
Since this is a trailing stop, you'll also need to enter a trailing step amount. The trailing step dictates how much the Germany 30 needs to move before your stop moves with it. So if you have set your stop to move every time the Germany 30 moves five points, then it will move up to 12,545 when the Germany 30 hits 12,560, and so on.
The Germany 30 hits a high of 12,593 before retracing, meaning that the trailing stop will be triggered at 12,575, earning you a profit. If you'd used a normal stop on the trade, it would have closed your position at 12,540, earning you a loss.
