Cboe EDGX Depth

Cboe EDGX disseminates full depth-of-book data for their exchange through their Pitch Feed, which Databento receives over UDP multicast in our NY4 data center.

The Multicast Depth of Book (Pitch) Specification is available as a PDF from Cboe's website.

Info
The Databento team is currently working on this article.

Timestamps

Cboe messages received by Databento will generally include one timestamp with nanosecond precision. As with all of our datasets, we also collect a ts_recv timestamp when the packet was received by our capture server.

Databento Field	Pitch Field	Description
`ts_recv`	N/A	The capture-server-received timestamp.
`ts_event`	Time + TimeOffset	The matching-engine-received timestamp.
`ts_in_delta`	None	The difference between `ts_recv` and `ts_event`. Redundant and can be safely ignored.

More details about our timestamps are available in our timestamping guide.

Flags

For Cboe EDGX Depth, the F_PUBLISHER_SPECIFIC flag is used in the MBO schema to indicate Retail Priority Orders (RPOs). MBO messages with action A will have the F_PUBLISHER_SPECIFIC flag set if the order is an RPO. This flag will not repeat on subsequent modifications or cancellations.

Retail Priority changes the order allocation priority model on EDGX to price-retail priority-time priority. Thus, Retail Priority Orders will have priority ahead of all other available interest at a price level.
