The starting exchange rate of the trailing stop is the exchange rate when the trailing stop is lowered, not the exchange rate when the position is opened (if the trailing stop is lowered when the position is opened, then the trailing stop is The starting price is the exchange rate when the position was opened).
For example, if you short the pound at 1.7539, set the stop loss at 1.7566 and the moving stop loss at 30 points when placing the order, then when the exchange rate drops to 1.7509, the platform will automatically move the stop loss to 1.7536 .
But if you do not modify the stop loss at the same time or in the middle of placing the order, and then place the trailing stop loss at this time, the starting exchange rate of the trailing stop loss will be the exchange rate at the time when you place the trailing stop loss, or In the example just now, for example, when the market rises to 1.7556, you place a trailing stop loss or modify your stop loss price. At this time, the starting exchange rate of the trailing stop loss is 1.7556 instead of 1.7539. When the market falls to 1.7526 , the platform will automatically move the stop loss to 1.7536 (the stop loss level is set at 1.7566).
