If EUR/USD moves in your favor, e.g. to .7457, the stop order will automatically adjust to .7427 - always 30 pips from the live rate.
Select Trailing Stop from the 'Type' drop down menu, as shown. In addition to the regular order parameters, you will be prompted to specify Trailing Points, which is the number of pips from the current rate at which you want the stop loss order to be executed. The system accepts Trailing Points between 10 and 1,000.
The advantage of a trailing stop is that the order automatically "trails" the rate if the position moves in your favor, offering the potential for greater gains while still guarding against price declines .
