close StopOrder

Hello,

If a cBot places two Orders, a MarkeOrder and a StopOrder, what code can I use to close the StopOrder when the MarketOrder hits its TakeProfit = 10 pips?

Kind regards

if (_MA_cross_down && shortPosition == null)
            {
                ExecuteMarketOrder(TradeType.Sell, Symbol, Symbol.NormalizeVolume(Volume), label, StopLoss, TakeProfit);

            }

            if (_MA_cross_down && shortPosition == null)
            {
                double targetPrice = Symbol.Ask + PipsAway * Symbol.PipSize;
                PlaceStopOrder(TradeType.Buy, Symbol, Volume2, targetPrice, label_2, StopLoss, TakeProfit);
            }
