(*) Note:

LO – Limit Order: LO is a buying or selling order at a specific price or at a better price, is given a specific price, and validates until the end of trading day or until the order is cancelled.

MP – Market Price Order: Orders to match at the best counter-bids/asks available in the market at the time of input and shall match forward to the next best prices available. Market Price Order is only available and effective during Continuous Matching period. Should there be no counter LO at the time of input of Market Price Orders, the Market Price Orders will automatically be cancelled. Some types of Market Price Orders:

MTL - Market-to-Limit: In the case that there are no more counter-bids/asks, remaining unmatched volume of MTL Orders will automatically be changed into Limit Orders

MOK - Match-or-Kill: Order must be executed in its entirety at the time of input; otherwise, the entire order will be canceled.

MAK - Match-and-Kill: Order can be executed partially or entirely, and the remaining unmatched order will be canceled.

ATC – At-the-close: The order at opening price or closing price, which is not given a specific price, is called ATC. ATC Orders have higher priority to match than Limit Orders (even Limit Orders at Ceiling Price or Floor Price). At the end of the effective session, unmatched ATC Orders or unmatched volume of partially matched ATC Orders will automatically be cancelled.

PLO: The buy/sell order at closing price, which is used in post-session transaction. PLO is matched right after a counter order appears and is automatically cancelled after post-session transaction has ended. PLO is not allowed to be input into system when there is no matched order in continuous order matching session and closing periodic order matching session.
