Place order

​

What you are doing

​

When orderType is post

• Use post when you want your risk to sit on the book until another user matches you (or you cancel).
• If you want to immediately take existing liquidity, use the same endpoint with orderType set to anything other than post (e.g. limit).
• Orders settle in coins or cash depending on your account’s current player mode — see Place coins orders and Switch player mode.

​

Request body (field by field)

​

Example response

• createdSessions — one entry per submitted order.
• matched — instant fills (usually empty for a pure post).
• unmatched — what is still live: use orderID with Cancel order / Look up single order; offered / remaining show how much risk is still working.
