Order

There are only three main types of order available at the CSX:

Limit Order - The order where the bid order price is maximum offer price and ask order price is minimum offer price.
Example: A bid limit order of 4,000 KHR shall be traded at 4,000 KHR or lower, and an ask limit order of 4,000 KHR shall be traded at 4,000 KHR or higher.
Market Order – The order to immediately buy or sell a stock at the best price available. However, it is not allowed for liquidity providing activities and the first trading of initially listed securities. The market order can have two affixed conditions: Fill or Kill (FOK) and Fill and Kill (FAK). They can only be used during the multiple-price auction and only when there is an order available at the opposite side.

FOK Market Order: the order shall be immediately cancelled if the quantity of order cannot be fully executed.
Example: FOK market order to buy 200 shares of stock A can be matched ONLY when there is (are) ask order(s) with (total) quantity ≥ 200 shares.

FAK Market Order: the order shall be immediately cancelled if the quantity of order cannot be executed (fully or partially). If partially executed, the remaining quantity of order shall be cancelled right after the order matching.

Example: FAK market order to buy 200 shares of stock B will be matched with the opposite side orders of any quantity, let say 50 shares. The unmatched quantity of 150 shares will be automatically and immediately cancelled.
