# Place a limit order

> Book a signed draft. The relay re-derives every term and checks the taker's funds and approval.

<ParamField body="draft" type="object" required>The draft from `prepare`, unchanged.</ParamField>
<ParamField body="signature" type="hex" required>The taker's signature over the draft's `typedData`.</ParamField>
<ParamField body="erc2612" type="object">`{ value, deadline, v, r, s }` when the sell token supports EIP-2612 and Permit2 is not yet approved.</ParamField>

Returns `201` with the order. The keeper leader auctions it every `LIMIT_POLL_MS` (5 s) while its price is
within 150 bps of the oracle mid, and fills it through `executeLimit` when a resolver meets the price.
