What do you mean by a discount on big deals? Such as 10% discount or something.

Block trading, also known as block trading, refers to the securities trading in which the single transaction declaration reaches the prescribed minimum, the buyer and the seller reach an agreement through agreement, and the transaction is confirmed by the exchange.

When you say "discount", you mean the rise and fall of the stock price. When you say "10% discount", you should refer to the large-scale transaction of the securities with price limit of 10% on that day.

Block trading shall be conducted within the time limit of the normal trading day of the exchange. Block trading of securities with price limit should be within the price limit of the day, and block trading of securities without price limit should be within 30% of the previous closing price within the bidding time of the day or between the highest and lowest trading prices. The transaction price is determined through negotiation between the buyer and the seller and confirmed by the stock exchange.

The transaction price of a block trade shall not be regarded as the closing price of the securities on that day. Block trading volume is included in the total trading volume of securities after the close. However, block trades are not included in the index calculation, so it has no effect on the index of the day.
