Description

Cboe EDGX Exchange, Inc. proposes to amend Rule 13.8(b) to describe the data sources for its Cboe One aggregated market data feed, rather than list specific data elements and message types. The feed draws on the Exchange and affiliated exchanges’ Multicast Depth feeds and information from securities information processors. The amendment describes the two feed versions, Cboe One Summary and Cboe One Premium, according to the quotation information each provides. The notice states that the proposed change does not change the feed’s content.
