1. When the futures contract reaches the daily limit, the price increase cannot be continued. If you want to buy, you have to queue up. It will be sold soon. Generally speaking, all transactions stipulate that the list of buying positions can be ranked in front of the list of selling positions. When a futures contract has a buy (sell) declaration with a stop-loss price, a sell (buy) declaration without a stop-loss price, or a deal with a sell (buy) declaration within 5 minutes before the closing of a trading day, but no stop-loss price has been set, that is, there is only one-sided quotation or the unilateral quotation is insufficient, it is called a stop (short for unilateral market).

2. The price limit system means that the transaction price of a futures contract in a trading day cannot be higher or lower than a certain fluctuation range based on the settlement price of the contract in the previous trading day, and the quotation exceeding this range will be regarded as invalid and cannot be traded. Under the price limit system, the settlement price of the previous trading day plus the maximum allowable increase constitutes the upper limit of the price increase of that day, which is called the daily limit; The settlement price of the previous trading day MINUS the maximum allowable decline constitutes the lower limit of the price decline, which is called the daily limit. Therefore, the price limit is also called the maximum fluctuation limit of daily price.
