Prices, Order Types & Validity

An Enhanced Limit Order is a feature that is applicable to HKEX orders. It is an order to buy or sell at a specific price or better, allowing matching of up to 10 price queues.

An At-Auction Limit Order (ALO) means an order type with a specified price placed during Pre-Opening Session (POS) (0900 to 0920) or Closing Auction Session (CAS)(1600 - 1608).
