2) Order matching method

Continuous order matching method: is a method performed by the trading system on the basis of matching buy and sell orders of futures contracts as soon as the order is entered into the trading system;

Periodic order matching method: is a trading method performed by the trading system on the basis of matching buy and sell orders at a specified time;

Agreement order matching: is a trading method in which the buyer and seller agree on the trading conditions, then notify the securities company to record the transaction results into the trading system. Or the buyer/seller goes through a securities company to find a counterparty trading partner.

3) Order matching principles

Price priority:

• Buy orders with higher prices are given priority to be executed first.
• Sell orders with lower prices are given priority to be executed first.

Time priority: In case buy or sell orders have the same price, the order entered into the trading system first has priority for execution.
