Cancel or Modify Orders

cancel_order Cancel Order

TradeClient.cancel_order(account=None, id=None, order_id=None)

Description

Cancel a previously submitted order. Order cancellation, like order placement, is processed asynchronously. Calling this method confirms that the cancellation request has been successfully sent, but the final cancellation result will be handled asynchronously by the system.

After submitting an order via TradeClient.place_order, the order may transition through several states depending on market and system conditions:

Orders that are fully filled or rejected cannot be canceled
Only orders in submitted or partially filled states are eligible for cancellation

For details on possible order states, please refer to TradeClient.get_order.

To cancel multiple orders, useTradeClient.get_open_orders to retrieve all pending orders, then submit cancellation requests individually. If an order has already been submitted for cancellation, do not resend the request. After issuing a cancellation request, wait briefly and re-query open orders to confirm the updated status.

Parameters

Parameter	Type	Required	Description
account	str	No	Account ID. If not provided, the default account from `client_config` is used
id	int	Yes	Global order ID. Recommended for order cancellation. Obtain this value from `Order.id` after placing an order
order_id	int	No	Local order ID. Obtain this value from `Order.order_id`

from tigeropen.trade.trade_client import TradeClient
from tigeropen.tiger_open_config import TigerOpenClientConfig
client_config = TigerOpenClientConfig(props_path='/path/to/your/properties/file/')
