Direct Market Access (DMA)
Direct Market Access (DMA) is the trading method by which a member company allows eligible investors to enter trading orders via their electronic Order Management System (OMS) which are then sent to the brokers’ trading system. Customer orders pass through the member's risk management system before being routed and queued in the SET trading system. Only Automatic Order Matching (AOM) is allowed for DMA trading, and Trader ID “D9999” must be specified in trade orders. Importantly, a member must be granted prior approval before providing DMA services to clients.
