There are two possibilities for this phenomenon, that is, many large orders are sold without pending orders:

The first reason may be because of the time difference, the transaction is too fast, and the order may be only a few tenths of a second away, so that the system didn't have time to display it;

The second reason may be that the main force entrusts transactions with different accounts at the same time.

Second, what is a pending order transaction?

Pending order transaction means that once the price specified by the customer reaches or exceeds the price specified by the customer, the customer's instructions are executed to complete the transaction, and the transaction price is the real-time quotation of the bank. There are four types of pending orders: buy limit, sell limit, buy stop and sell stop.

The exchange rate of pending orders is better than the real-time exchange rate of banks, otherwise, transactions will be conducted at the real-time exchange rate.

Pending orders are valid on the same day. Before the transaction, customers can also take the initiative to cancel the unfinished orders. After a customer makes a pending order transaction, the pending order amount is immediately frozen, and the amount cannot be used for payment or other purposes within the trading day unless the transaction is cancelled.

In the electronic trading of the securities market, pending orders are equivalent to entrustment, that is, when investors decide to buy or sell stocks, they send instructions to the trading system by telephone and computer.

Third, the difference between antithesis and duality.

Reversal: refers to the transaction between multiple accounts managed by the main force, that is, buying and selling by oneself. This is the usual method of the main force, and its purpose is to shock the position or attract followers or boost the stock price.

Counterattack: also known as relative entrustment or collusion, refers to the negotiation between the main force and the main force. One side pours chips from the other side, usually within a certain price range, but the actual transaction price is quite different from the agreed price.
