Feed Connectivity Requirements

The Cboe One Options feed is available to users who meet the minimum bandwidth requirements to receive the feed via cross-connect, dedicated circuit, or a supported carrier.

Cboe One Options real-time events are delivered using a published range of multicast addresses divided by symbol range units. Dropped messages can be requested using a TCP/IP connection to one of Cboe One’s GRP servers with replayed messages being delivered on a separate set of multicast ranges reserved for packet retransmission. Intraday, a spin of the current aggregated book, may be requested from a Spin Server.

Multicast addresses and ports for the Cboe One Options feed are listed in Multicast Configuration.
