Don't miss out on the IPO surge! The trailing stop order feature can assist you by automatically placing an order to lock in profits.
The core function lies in 'adjusting stop-loss based on market price.' Simply put: when the share price rises, your stop-loss line follows upward; when the share price falls, the stop-loss line remains unchanged, and once it drops below the set percentage, the system will automatically sell for you!
