Routing instructions are mandatory for orders transmitted over which interface?

Routing instructions are mandatory for orders transmitted over which interface?

• A. OTI only
• B. STI only
• C. STI and OTI
• D. Neither

Answer: (B)

Routing instructions are about telling the system where to send an order. The STI interface is designed to route orders to multiple destinations, so the instruction must specify the exact route or destination to ensure the order reaches the correct venue or counterparty. In contrast, the OTI interface is a direct transmission path to a predefined target, so there’s no need to separately specify routing because the destination is already determined by the OTI connection. Therefore, routing instructions are mandatory only for orders transmitted over the STI.
