StopOrder after MarketOrder S/L

Hello,

What code do I use to place a SellStop Order after the SellOrder S/L is hit? The SellStop Order should be placed placed at the price where the SellOrder was executed.

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);
            }



        }

        private void PositionClosed(PositionClosedEventArgs args)
        {
            var pos = args.Position;
            if (pos.Label == label && pos.NetProfit > 0)
            {
                foreach (var order in PendingOrders)
                {
                    if (order.Label == label_2 && order.OrderType == PendingOrderType.Stop)
                    {
                        CancelPendingOrder(order);
                    }
                }
            }

        }
