Live Market Data

Market status

Lifecycle changes: a market opening, pausing, closing, resolving.

WSSawait stream.watch_market_status()SDK stream · your process · venue credentials

Self-hosted. Opened from your own process straight to the venue. Nothing here runs on Synpath's servers.

state is Synpath's word, one of created, open, paused, closed, determined, settled or updated; native keeps the venue's own word and result the winning side where the venue names one.
