After filling in the name, quantity and price of the stock to be bought or sold, it is called a pending order to prepare for the system transaction. If the pending order is not closed, it may usually be caused by the following reasons:

1, the price has no advantage: for example, if the price is lower than others, then the high price will be traded first. When selling, the price is higher than others, so the lowest price is the first to clinch a deal.

2. Time has no advantage: when the pending order price is the same, whoever hangs the order first will make a deal, and naturally there is no time advantage when the pending order is late.

3. There is no advantage in the transaction amount: the price and time of the two pending orders are the same, but the others are bulk transactions, so the bulk transactions are made first.
