Platform nuances

info

When instrument is omitted, all working orders across the entire account are cancelled. When instrument is provided, only orders for that instrument are affected. Use the instrument filter when you want to cancel protective orders on a specific position without touching orders on other instruments in the same account.

WebSocket API

This request can also be made over the WebSocket API. The account path parameter and request body fields are all passed inside args.

{
  "action": "rpc",
  "id": "my-request-id",
  "api": "CancelOrders",
  "args": {
    "account": "Sim101",
    "instrument": "ES 09-26"
  }
}

Tradovate

Cancel orders by account and/or instrument Tradovate

Cancels working orders on one linked Tradovate account, optionally narrowed to one instrument. No NinjaTrader add-on is involved: the command runs server-side with the same validation, Account Manager locks, and Trade Copier fan-out as a webhook signal.

Endpoint

POST /v1/api/tv/accounts/{account}/orders/cancel

Headers

Name	Value
Content-Type	application/json
Authorization	Bearer <token>

Path parameters

Name	Type	Required	Description
account	string	Required	Tradovate account name, for example DEMO12345678.

Body parameters

Name	Type	Required	Description
instrument	string	Optional	Limits cancellation to one instrument. Accepts continuous (ES1!), NT8 (ES 09-26), or Tradovate (ESU6) forms.

Send {} to cancel every working order on the account.

Code examples

Python

import requests

token = 'my-secret-token'

url = "https://app.crosstrade.io/v1/api/tv/accounts/DEMO12345678/orders/cancel"
headers = {
    "Authorization": f"Bearer {token}",
    "Content-Type": "application/json"
}
data = {
    # "instrument": "ES1!"
}

try:
    response = requests.post(url, headers=headers, json=data)
    print(f"Response Code: {response.status_code}, Response Text: {response.text}")
except Exception as e:
    print(f"An error occurred: {e}")

JavaScript

const token = 'my-secret-token';

const url = "https://app.crosstrade.io/v1/api/tv/accounts/DEMO12345678/orders/cancel";

  .catch(err => console.error(err));

cURL

TOKEN="my-secret-token"

curl -X POST "https://app.crosstrade.io/v1/api/tv/accounts/DEMO12345678/orders/cancel" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{}'

Response

The response is the response envelope with api set to cancel_orders_scoped. Its response reports the cancellation count, cancelled order ids, and per-order results.

{
  "success": true,
  "destination": "tradovate",
  "api": "cancel_orders_scoped",
  "account": "DEMO12345678",
  "response": {
    "cancelled": 0,
    "orders": [],
    "detail": "No working orders matched."
  },
  "durationMs": 214
}

Platform nuances

• Omitting instrument affects every working order on the account. Include it to avoid touching orders on other contracts.
• Successfully cancelled copied leader orders are replayed to mapped follower orders.
• Partial cancellation failures are surfaced rather than reported as a clean sweep.
• Account Manager locks apply. On failure, the response envelope has success: false and an error message.
