[PYTHON] It seems that cancelall childorders can be used to cancel all parent orders (special orders) with the bitflyer API

Although the name is cancelallchildorders, parent orders (special orders) are also canceled.

Here in the documentation https://lightning.bitflyer.com/docs#%E3%81%99%E3%81%B9%E3%81%A6%E3%81%AE%E6%B3%A8%E6%96%87%E3%82%92%E3%82%AD%E3%83%A3%E3%83%B3%E3%82%BB%E3%83%AB%E3%81%99%E3%82%8B

With pybitflyer

    def cancelallchildorders(self, **params):
        """Cancel All Orders

        API Type
        HTTP Private API

        product_code: The product for the corresponding order. Designate "BTC_JPY", "FX_BTC_JPY" or "ETH_BTC".

        If the parameters are correct, the status code will show 200 OK.

        if not all([self.api_key, self.api_secret]):
            raise AuthException()

        endpoint = "/v1/me/cancelallchildorders"
        return self.request(endpoint, "POST", params=params)


The following is the result when executed in our environment on 2020/01/18. There is a good chance that it will behave differently if it is executed in a different environment or due to a specification change on the API side. When creating a BOT, etc. using the following results, please make it after thorough verification.

Sample (with parent order)

cancel = bfapi.cancelallchildorders(product_code=SYMBOL)

→ Nothing is displayed.


Execution result

[{'id': 263032602,
  'parent_order_id': 'JCP20200118-065956-905830',
  'product_code': 'FX_BTC_JPY',
  'side': 'BUYSELL',
  'parent_order_type': 'IFDOCO',
  'price': 1006594.0,
  'average_price': 0.0,
  'size': 0.03,
  'parent_order_state': 'CANCELED',
  'expire_date': '2020-01-18T08:39:56.61',
  'parent_order_date': '2020-01-18T06:59:56.61',
  'parent_order_acceptance_id': 'JRF20200118-065956-127674',
  'outstanding_size': 0.0,
  'cancel_size': 0.03,
  'executed_size': 0.0,
  'total_commission': 0.0},

Make sure parent_order_state is'CANCELED'


I am executing an IFDOCO order with a for statement. I thought that it should be initialized by canceling all positions and canceling all orders at the beginning of the for loop, and I came up with this result. I hope it will be useful for those who want to achieve the same thing.
