(1) Order At present, there are three kinds of trading orders commonly used in domestic futures orders: market order, limit order and cancellation order. The quotation of the trading order can only be within the contract price limit, and the quotation exceeding the price limit is considered invalid. The minimum order quantity for each transaction order is 1 lot. Different varieties. The maximum singular number is also specified for each exchange. For example, stock index futures stipulate that the maximum order quantity of a limit order shall not exceed 100 lots.

(1) The market order refers to the closing order based on the best price that can be executed in the market at that time without ceiling price. The unfinished part of the market order will be automatically cancelled. The market order can only be matched with the limit order, and the transaction price is the price that the opponent hangs immediately. So when using the market price list, you don't need to enter the entrusted price, just click the keyboard. During the period of call auction before the opening, no market orders will be accepted. Some investors often mistakenly think that placing an order at the market price can be the fastest and the most satisfactory price, but this is not the case. Because the market order is aimed at the first transaction, it is often difficult to give consideration to the optimality of the price. So remind investors that in futures trading, market orders can only be traded at the fastest speed, but they may get poor transaction prices, and once placed, they cannot be changed or revoked. Therefore, when the price fluctuates greatly, investors may face greater price risk if they choose the market price list.

(2) A limit order refers to an order with a price limited by the trader or a better price. When placing a limit order, the trader must specify a specific price. Its characteristic is that it can be traded according to the expected price of customers, and the transaction speed is relatively slow, and sometimes it is impossible to clinch a deal. When buying a limit order, the transaction must be made at or below the limit price; When selling, the transaction must be made at or above the price limit. The price limit order is valid on the same day, and the unfinished part can be revoked.

(3) Cancel the order means that after the price limit order is issued, there is no transaction or only partial transaction, at which time the trader has the right to cancel the order. Customers can cancel the previous order through the trading system, so that the original limit order will be invalid or partially invalid. For example, after limit orders issued "sell stock index futures IF09 12 contracts 10 lots with a price limit of 3 188 points", only five lots were sold. At this time, the trader issued a withdrawal order, and the original limit order was partially invalid, and the remaining 5 lots would not be sold.
