Error with STOP_LOSS_LIMIT Order Types

[alphazwest]

I am trying to place a new order of type STOP_LOSS_LIMIT as follows:

client.create_order( symbol="ABCXYZ", side="SELL", type="STOP_LOSS_LIMIT", timeInForce="GTC", quantity=1.5, price=123.456, stop_price=123.123 )

I get the following error message:

binance.exceptions.BinanceAPIException: APIError(code=-1104): Not all sent parameters were read; read '8' parameter(s) but was sent '9'. Upon deeper inspection, the following API parameters are being sent by this library:

{ 'symbol': 'ABCXYZ', 'side': 'SELL', 'type': 'STOP_LOSS_LIMIT', 'timeInForce': 'GTC', 'quantity': 1.5, 'price': 123.123, 'stop_price': 123.456, 'timestamp': valid_unix_timestamp_int, 'signature': '64-char hexadecimal string' }

There are clearly 9 parameters being passed, as indicated by the error message. However, the ones specified by my application are essential and I can only guess which one the API is complaining about.

Regular BUY/SELL orders work w/o issue.
