Which of the following are market data feeds used by SIX Exfeed Ltd to publish data?

• A. SMF, QMF, MDI, IMI.
• B. SMF (Swiss Market Feed) and QMF (Quote Market Feed) only.
• C. MDI (Market Data Interface) and IMI (ITCH Market Data Interface) only.
• D. SWX Market Data Feed.

Answer: (C)

Exfeed publishes market data through two main interfaces: the Market Data Interface (MDI) and the ITCH Market Data Interface (IMI). MDI provides the standard, wide-ranging market data feed, delivering quotes, trades, and related information in a structured way. IMI reflects the ITCH-style, low-latency data feed, offering an event-driven stream of order-book updates and trades. These two together are the channels SIX Exfeed uses to distribute data. The other terms describe different feed families or separate feeds from the Swiss market (for example, SWX Market Data Feed), which are not the Exfeed publication channels in this context. So the right combination is MDI and IMI only.
