title: Binance api futures error: {"code":-2015,"msg":"Invalid API-key} using private_post_order_oco (but ID works with everything else)
body: <p>I am having a problem using the Binance Python API.</p>
  <p>I am using Python3.7 on Ubuntu</p>
  <p>Basically, when making the call below, I get an error:
  <strong>{&quot;code&quot;:-2015,&quot;msg&quot;:&quot;Invalid API-key,</strong></p>
  <p>The thing is that this ID has worked fine on the Binance TESTNET for LIMIT and MARKET orders. This is the only order type I am having problems with. I also logged the message here:</p>
  <p><a href="https://github.com/ccxt/ccxt/issues/8089" rel="nofollow noreferrer">https://github.com/ccxt/ccxt/issues/8089</a></p>
  <p>I was attempting to do this on the FUTURES exchange.</p>
  <pre><code>retval = self.exchange.private_post_order_oco({
      'symbol': symbol,
      'side': side,
      'quantity': self.exchange.amount_to_precision(symbol, amount),
      'price': self.exchange.currency_to_precision( quote_currency, abs(float( in_last_chance_price ))),
      'stopPrice': self.exchange.currency_to_precision( quote_currency, abs(float(in_stop_price))),
      'stopLimitPrice': self.exchange.currency_to_precision( quote_currency, abs(float( in_limit_price ))),
      'positionSide': self.position_side[side],
      'listClientOrderId' : mainXChangeID,
      'limitClientOrderId': mainXChangeID + '-L',
      'stopClientOrderId' : mainXChangeID + '-S',
  })
  </code></pre>
  <p>Any help, hints or advice of what could be going on would be greatly appreciated.</p>
