If the original entrustment has been completed before the investor completes the withdrawal, it cannot be withdrawn.
If investors want to use the locked funds (want to change the purchase price or not want to buy) or stocks (want to change the selling price or not want to sell) on the same day, they must cancel the entrustment by withdrawing the order before they can use the locked funds or stocks.
To sum up, there are three main situations in which bills are cancelled:
The first situation: to chase high, you must buy at a higher price, and you have no funds at hand. You need to remove the previous entrustment and chase it in at a better price;
The second case: cutting meat, the stock price has been adjusted very badly, and you have to sell it at a lower commission price to close the deal. At this time, you need to cancel the previous sales order;
The third situation: As mentioned above, if you find that you can buy or sell at a better price, then you should cancel the previous entrustment and choose a better price to entrust.
