One card for the feed this host quotes.

The public page names the upstream, the revision, and whether the feed is live. Quote rows stay on the trading side.

Feed card

The feed card for this host names the upstream being quoted, the revision a client last saw, and whether that feed is live. The card does not return quote rows. On Brant Field that source id is src_694579a0.

How the card works

Upstream

Named feed

Each host quotes one upstream. The card is how a client learns which one.

Revision

Cache check

The revision moves when the upstream changes. Clients compare it with the copy they stored.

Status

Live or paused

A paused feed stays on the card so a client can tell a quiet market from a stopped source.
