Client Order ID's for OCO order

API Spot/Margin API
1

Hi there

I’m placing an OCO order and providing the three client order ID’s (i.e. listClientOrderId, stopClientOrderId, & limitClientOrderId).

Two of the order ID’s I provide are acknowledged and returned by the Binance API but the limitClientOrderId is not. Instead, it generates its own random unique limitClientOrderId.

I’m using a third-party connector and this is the query string it is posting:

symbol=BTCBUSD&isIsolated=true&side=BUY&sideEffectType=AUTO_REPAY&type=OCO&quantity=0.001&price=19072.4&stopPrice=19082.4&stopLimitPrice=21082.4&stopLimitTimeInForce=GTC&listClientOrderId=2209281154002&stopClientOrderId=2209281154003&limitClientOrderId=2209281154004&newOrderRespType=FULLtimestamp=1664319287657&signature=...

And here is the response I get back (note the random unique limitClientOrderId):

  orderListId: 75289366,

      stopPrice: '19082.40000000'
    },
    [Object: null prototype] {
      symbol: 'BTCBUSD',
      orderId: 6261337531,
      orderListId: 75289366,
      clientOrderId: 'RCVNxokAyH8AnQg3kkkugl',
      transactTime: 1664319287983,
      price: '19072.40000000',
      origQty: '0.00100000',
      executedQty: '0',
      cummulativeQuoteQty: '0',
      status: 'NEW',
      timeInForce: 'GTC',
      type: 'LIMIT_MAKER',
      side: 'BUY'
    }
  ]
}

Could this be a bug in the Binance API?

Thanks in advance
