Open a market order window and set up your trade. I am making a market trade at the price of 78.15 on AUD/JPY.
Notice that I have checked the checkbox that says Trailing Stop. This box is set the same way you set a regular stop, you just enter the starting price. For this trade I am going to enter a tight stop at 78.00. This gives me a stop that trails 15
pips behind my entry price.
