Market status

A market has one of seven stored statuses. These are the values ?status= accepts — lowercase, comma-separated, e.g. ?status=open,pre_open.

Status	Meaning
scheduled	Created and ready to pre-open. No orders accepted yet.
pre_open	Accepts limit orders ahead of open. No trades, and no market orders.
open	Open for all orders and trades.
closed	The result is known. No new orders; pending orders are cancelled. Awaiting admin confirmation or feed delay.
resulted	Result confirmed. Settlements generated for all trades.
cancelled	Cancelled. No new orders; pending orders are cancelled. Awaiting confirmation.
voided	Cancellation confirmed. Void settlements generated.

An uppercase value returns 400. Omit the parameter entirely and you get every non-archived market — not just the open ones.

suspended is not one of them

A response’s status field can read suspended, which is not in the list above and cannot be filtered on. It is derived at render time:

trading == false  AND  status in (open, pre_open)   ->   suspended

So a market returned by ?status=open can report "status": "suspended". The filter is not wrong — that market genuinely is open — it simply is not taking trades at this moment.

The two fields answer different questions:

Field	Answers
status	Where the market is in its lifecycle
trading	Whether it is accepting orders right now

A market you can actually trade against has status: open and trading: true.

?trading=true is not applied

The parameter is accepted, but the response is identical with or without it, so a filtered call still returns markets with trading: false. Until that is fixed, filter on the trading field client-side:

tradeable = [m for m in get("/api/v1/markets?status=open")["markets"] if m["trading"]]

Or use the GraphQL query in the quickstart, which applies both conditions server-side.

Events have their own statuses

Do not confuse these with event status, which is a separate, shorter set: scheduled, in_progress, completed, cancelled. A market carries its event’s status alongside its own as event_status.
