# Cancel All Orders

You can cancel **all active orders** for your account (optionally filtered by **symbol**) over **WebSocket** using the `cancel_all_orders` message.

## Example Request

```json theme={null}
{
  "type": "cancel_all_orders",
  "params": {
    "symbol": "AAPL-USD" // Optional
  }
}
```

## Sample Code

<CodeGroup>
  ```python python theme={null}
  # Python (websocket-client)
  import json, websocket

  API_KEY = "YOUR_API_KEY"

  def send(ws, obj): ws.send(json.dumps(obj))

  def on_open(ws):
      # Authenticate
      # https://docs.qfex.com/websocket/channels/trade/authenticate#how-it-works
      send(ws, {"type": "auth", "params": { "hmac": { "public_key": "qfex_pub_xxxxx", "nonce": "c0ffee...", "unix_ts": 1760545414, "signature": "5f2e..." }}})
      # Cancel all orders
      send(ws, {"type": "cancel_all_orders", "params": {}})

  ws = websocket.WebSocketApp(
      "wss://trade.qfex.com?api_key=YOUR_API_KEY",
      on_open=on_open,
      on_message=lambda _, m: print("Message:", m)
  )
  ws.run_forever()
  ```

  ```javascript node theme={null}
  // Node.js (ws)
  import WebSocket from "ws";
  const ws = new WebSocket("wss://trade.qfex.com?api_key=YOUR_API_KEY");
  const API_KEY = "YOUR_API_KEY";

  ws.on("open", () => {
    // Authenticate
    ws.send(JSON.stringify({ type: "auth", params: { api_key: API_KEY } }));
    // Cancel all orders
    ws.send(JSON.stringify({ type: "cancel_all_orders", params: {} }));
  });

  ws.on("message", (msg) => console.log("Message:", msg.toString()));
  ```

  ```go go theme={null}
  // Go (gorilla/websocket)
  package main

  import (
  	"log"
  	"github.com/gorilla/websocket"
  )

  func mustWriteJSON(c *websocket.Conn, v any) {
  	if err := c.WriteJSON(v); err != nil { log.Fatal("write:", err) }
  }

  func main() {
  	c, _, err := websocket.DefaultDialer.Dial("wss://trade.qfex.com?api_key=YOUR_API_KEY", nil)
  	if err != nil { log.Fatal("dial:", err) }
  	defer c.Close()

  	// Authenticate
  	mustWriteJSON(c, map[string]any{
  		"type": "auth",
  		"params": map[string]any{"hmac": map[string]any{"public_key": "qfex_pub_xxxxx", "nonce": "c0ffee...", "unix_ts": 1760545414, "signature": "5f2e..."}}
  	})

  	// Cancel all orders
  	mustWriteJSON(c, map[string]any{
  		"type": "cancel_all_orders",
  		"params": map[string]any{},
  	})
  }
  ```

  ```java java theme={null}
  // Java (OkHttp WebSocket)
  import java.util.concurrent.TimeUnit;
  import okhttp3.*;

  public class CancelAllOrdersWs {
    public static void main(String[] args) {
      OkHttpClient client = new OkHttpClient.Builder()
          .pingInterval(20, TimeUnit.SECONDS).build();

      Request req = new Request.Builder()
          .url("wss://trade.qfex.com?api_key=YOUR_API_KEY").build();

      WebSocketListener li = new WebSocketListener() {
        @Override public void onOpen(WebSocket ws, Response r) {
          // Authenticate
          ws.send("{\"type\": \"auth\", \"params\": { \"hmac\": { \"public_key\": \"qfex_pub_xxxxx\", \"nonce\": \"c0ffee...\..\", \"unix_ts\": 1760545414, \"signature\": \"5f2e...\" }}}");
          // Cancel all orders
          ws.send("{\"type\":\"cancel_all_orders\",\"params\":{}}");
        }
        @Override public void onMessage(WebSocket ws, String text) {
          System.out.println(text);
        }
      };

      client.newWebSocket(req, li);
      try { Thread.sleep(Long.MAX_VALUE); } catch (InterruptedException ignored) {}
    }
  }
  ```
</CodeGroup>

## Example Response

Every cancelled order will generate an **order\_response** with status `CANCELLED`.

```json theme={null}
{
  "order_response": {
    "order_id": "5b309929-206f-40ec-804d-cbe46e81afc1",
    "symbol": "AAPL-USD",
    "status": "CANCELLED",
    "quantity": 1.0,
    "price": 200.0,
    "side": "BUY",
    "type": "LIMIT",
    "time_in_force": "GTC",
    "user_id": "0020ce8e-eaee-480e-8d7f-b9241d756ee5",
    "client_order_id": "my-client-oid",
    "quantity_remaining": 1.0,
    "trade_id": null
  }
}
```

<Note>
  This cancels **all open orders across all symbols** for the authenticated
  account, unless a `symbol` is specified. If you only want to cancel specific
  orders by ID, use the [Cancel Order](/websocket/channels/trade/cancel_order)
  endpoint instead.
