Second, the price limit system.

The price limit system means that the trading price of futures contracts in a trading day shall not be higher or lower than the prescribed price limit, and the quotation exceeding this limit will be regarded as invalid and cannot be traded. This is an important risk management system matching with the margin system, which at least ensures that each trader's margin can withstand the trading risk of one day. Theoretically, the trading risk of futures trading is controlled to a minimum through the daily debt-free settlement system (that is, the trader loses money in the day's trading and must make up the margin before the market opens the next day).

Third, the position limit system.

The position limit system refers to the system that the futures exchange limits the number of positions held by members and customers in order to prevent market price manipulation and excessive concentration of futures market risks on a few investors. If the amount exceeds the limit, the exchange may, as necessary, forcibly close the position or increase the margin ratio. This is an important measure for the exchange to control the degree of market risk and prevent the risk from expanding.

Fourth, the large household reporting system.

Large-sum declaration system means that when the speculative position of a certain variety of members or customers' position contracts reaches more than 80% (inclusive) of the speculative position limit stipulated by the exchange, members or customers (through brokerage members) should declare their funds and positions to the exchange. This is an important system closely related to the position limit system to prevent large households from manipulating market prices and control market risks.

Verb (abbreviation for verb) compulsory liquidation system

The forced liquidation system refers to the forced liquidation system implemented by the exchange or futures brokerage company to prevent further risk expansion when the trading margin of members or customers is insufficient and not replenished within the specified time, or when the number of positions held by members or customers exceeds the specified limit. This is an important system for exchanges or futures brokerage companies to control and resolve market risks.

In addition, the systems related to risk control also include the aforementioned daily debt-free settlement system and risk reserve system.
