The basic system of futures trading:

First, the position limit system.

The position limit system refers to the system that the futures exchange restricts the positions of members and customers in order to prevent the manipulation of market prices and the 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.

Second, the big report system.

The large-sum declaration system means that when the speculative position of a member or customer in a certain position contract reaches more than 80% of the position limit stipulated by the exchange, the member or customer should declare his capital and position to the exchange, and the customer must declare it through a brokerage member. The large household declaration system is another system closely related to the position limit system to prevent large households from manipulating market prices and control market risks.

Third, the physical delivery system

The physical delivery system refers to the system formulated by the exchange. When the futures contract expires, both parties to the transaction transfer the ownership of the goods contained in the futures contract according to the regulations, and settle the open contract.

Fourth, the deposit system

In futures trading, any trader must pay a certain proportion (usually 5- 10%) of the value of the futures contract he buys and sells as the fund guarantee for the performance of the futures contract, and then he can participate in the futures contract trading and decide whether to add funds according to the price change.

V. Price Limit System

The price limit system, also known as the daily maximum price fluctuation limit, means that the trading price fluctuation of futures contracts in a trading day should not be higher or lower than the specified price fluctuation range, and the quotation exceeding this price fluctuation range will be regarded as invalid and cannot be traded.
