# Place a new order

> Submits a signed limit or market order for a subaccount, specifying instrument, direction, amount, limit price and max fee, plus optional flags like time-in-force, reduce-only, post-only and MMP. The same endpoint also creates trigger orders (via trigger_type/trigger_price) and algo orders (via algo_type), though the two cannot be combined in one request. Requires a signed order payload and Orderbook trade scope for the instrument's asset; returns the created order with its assigned id and current status.
