ccxt.base.errors.OrderNotFound: binance {"code":-2011,"msg":"Unknown order sent."} when calling binance.cancel_all_orders without any open orders

[m-nez]

Calling binance.cancel_all_orders raises an error when there are no open orders. It should return an empty list of closed orders.

• OS: MANJARO
• Programming Language version: Python 3.10.4

import ccxt
binance = ccxt.binance(credentials)

Hello @m-nez, that depends on how the exchanges handle it, some exchanges will return a successful response + empty array as suggested, but some decided to consider this as an "error response". For the latter, we just wrap the original around a unified exception that users can easily catch.

You can emulate that behavior by doing this:

Example

result = []
    try:
       # your code here
        result = exchange.cancel_all_orders(....)
    except ccxt.OrderNotFound as e:
      # handle exception here

# remaining logic here

Maybe you need to specify the type of account, something like this: exchange.cancel_all_orders('BTCUSDT',{'type': 'margin','marginMode': 'cross'})
