# twapOrder | Hyperliquid exchange
> Places a TWAP (Time-Weighted Average Price) order that splits a large order into smaller slices executed over a specified duration.
You can only use this endpoint on the official Hyperliquid public API. It is not available through Chainstack, as the open-source node implementation does not support it yet. See [Hyperliquid methods](/docs/hyperliquid-methods) for the full availability breakdown.
This endpoint requires signature authentication. See our comprehensive [Authentication via Signatures guide](/docs/hyperliquid-authentication-guide) for implementation details.
Places a TWAP (Time-Weighted Average Price) order that splits a large order into smaller slices executed over a specified duration.
## Parameters
### Required parameters
* `action` (object, required) — The action object containing:
* `type` (string) — Must be `"twapOrder"`
* `a` (integer) — Asset index
* `b` (boolean) — Is buy order
* `s` (string) — Total size
* `r` (boolean) — Reduce only
* `m` (integer) — Duration in minutes
* `t` (boolean) — Randomize slice timing
* `nonce` (number, required) — Current timestamp in milliseconds (must be recent)
* `signature` (object, required) — EIP-712 signature of the action
### Optional parameters
* `vaultAddress` (string, optional) — Address when trading on behalf of a vault or subaccount
## Returns
Returns an object with the action status:
* `status` — `"ok"` if request processed
* `response` — Contains action result data
## Example request
```shell cURL theme={"system"}
curl -X POST https://api.hyperliquid.xyz/exchange \
-H "Content-Type: application/json" \
-d '{
"action": {"type": "twapOrder"},
"nonce": 1234567890123,
"signature": {...}
}'
```
```typescript @nktkas/hyperliquid theme={"system"}
import * as hl from "@nktkas/hyperliquid";
import { privateKeyToAccount } from "viem/accounts";
const wallet = privateKeyToAccount("0x..."); // viem or ethers
const transport = new hl.HttpTransport(); // public Hyperliquid mainnet
const client = new hl.ExchangeClient({ transport, wallet });
// Place a TWAP order (twapOrder)
const data = await client.twapOrder({
twap: {
a: 0, // asset index
b: true, // is buy
s: "1", // total size
r: false, // reduce only
m: 10, // duration in minutes (5–1440)
t: true, // randomize slice timing
},
});
console.log(data);
```
```python hyperliquid-python-sdk theme={"system"}
# The official hyperliquid-python-sdk does not expose a twapOrder exchange
# action (no Exchange.twap_order method as of this SDK version). Use the curl
# request above, or the @nktkas/hyperliquid TypeScript SDK, to place a TWAP order.
# The Python SDK can read TWAP slice fills via Info.user_twap_slice_fills(...).
```
## Use case
* **TWAP order** — Places a TWAP (Time-Weighted Average Price) order that splits a large order into smaller slices executed over a specified duration.
Always ensure your system clock is synchronized. Nonce must be within a reasonable time window of the current server time or the request will be rejected.
