-**Automatic Order Matching (AOM)** trading performs the order matching process according to price, then time, priority, without human intervention. After brokerage houses electronically send buy or sell orders from their offices to the SET mainframe computer, the CONNECT system queues the orders and arranges them according to a price-then-time priority. This means orders are first grouped according to price, with the best price taking precedence. Then, within each price group, orders are arranged according to time.+**Automatic Order Matching (AOM)** trading performs the order matching process according to price, then time, priority, without human intervention.

The SET CONNECT trading system continuously matches the first buy and sell orders in the queue, and, at the same time, confirms each executed transaction via the member's (broker's) terminal.
  
-The **Auction** matching is utilized in calculating the opening and closing prices of a security at the opening and closing of the trading hours. This method allows brokers to enter their orders to be queued for matching at a specified time at a single price that generates the greatest trading volumes for that particular stock.+The **Auction** matching is utilized in calculating the opening and closing prices of a security at the opening and closing of the trading hours.

 In **Put Through (PT) Trading**, when the trading value crosses over 10,000 units, which is equivalent roughly to 10 million Baht, an alternative method provided by TBX called “Put Through” must be selected. The counterparties can negotiate off the exchange. Once the deal is concluded, the seller can initiate the put through transaction, which then needs to be verified by the buyer. Once the confirmation process is completed, the buyer will allow that transaction to go to the next process, clearing and settlement. In **Put Through (PT) Trading**, when the trading value crosses over 10,000 units, which is equivalent roughly to 10 million Baht, an alternative method provided by TBX called “Put Through” must be selected.
