Overview

Cboe members may use the Cboe Global Cloud Equities TOP (TOP) feed to receive real-time top of book quotations and execution information from the following Equities Exchanges:

• BZX and EDGX US Equities Exchange platforms
• BXE, CXE, and DXE EU Equities Exchange platforms

The quotations received via TOP provide an aggregated size and do not indicate the size or number of individual orders at the best bid or ask. The TOP protocol also provides last trade price and size and cumulative volume data.

TOP cannot be used to enter orders. For order entry, refer to the appropriate U.S. or EU order entry specification.
