The way the Trailing Start and Step works is based off of your Entry Point and the movement in the profitable direction of your trade. So it start with your Entry Point which the other settings will help you adjust. Once a trade has been triggered, the Entry Point will show as the first Price column in your summary section of your platform where the trade is summarized. If you have a Stop Loss setting in place, the trade summary will also show the Stop Loss point as well. If the trade moves in your favor, the Trailing Start setting identifies when you would like to activate the first Trailing Step. This would be (Entry Point + Trailing Start) which will adjust the Stop Loss to be (Entry Point + Trailing Start - Trailing Step). Following this, the Trailing Step will be the only setting that will cause future adjustments at a rate of (Previous Point + Trailing Step) adjusting the Stop Loss to (Current Point - Trailing Step). Here is a numerical example with the settings of Trailing Start of 10 and Trailing Step of 10 so it is easier to follow:
Entered at 100. Trailing Start triggers at 110 (Entry Point plus Trailing Start). Stop Loss has now been moved to 100 (Entry Point + Trailing Start - Trailing Step). At 120 (Previous Trailing Step of 110 + Trailing Step of 10), Stop Loss is moved to 110 (Current - Trailing Step). At 130 (Previous Trailing Step + Trailing Step of 10), Stop Loss is moved to 120 (Current - Trailing Step).
Entered at 100. Trailing Start triggers at 110 (Entry Point plus Trailing Start). Stop Loss has now been moved to 100 (Entry Point + Trailing Start - Trailing Step). At 120 (Previous Trailing Step of 110 + Trailing Step of 10), Stop Loss is moved to 110 (Current - Trailing Step). At 130 (Previous Trailing Step + Trailing Step of 10), Stop Loss is moved to 120 (Current - Trailing Step).
