The take profit and stop loss price set by the order is only a critical value, and the corresponding order transaction will be triggered only if it is greater than or equal to or less than or equal to this price. Product quotations are jumping rather than continuous quotations (that is, quotations are irregular, and the market does not necessarily have a stop-loss or take-profit price you set), so the price at the trigger moment may not necessarily be equal to the set price.
