I don't undestand....

 I have a little problem, when I executed this cbot for example in EURUSD and I stoped one position in other market, the cbot executed new orders in EURUSD.... I don't know where is the problem.

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;

namespace cAlgo
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class sergi : Robot
    {

        [Parameter("Volume", DefaultValue = 1000)]
        public int Volume { get; set; }

        [Parameter("Stop Loss (pips)", DefaultValue = 20, MinValue = 1)]
        public int StopLossInPips { get; set; }


        protected override void OnStart()
        {

            Positions.Closed += closedposition;
            ExecuteMarketOrder(TradeType.Buy, Symbol, Volume, "Sergi", StopLossInPips, 0);
            ExecuteMarketOrder(TradeType.Sell, Symbol, Volume, "Sergi", StopLossInPips, 0);

        }

        public void closedposition(PositionClosedEventArgs arg)
        {
            var position = arg.Position;


            if (position.NetProfit < 0)
                Positions.Closed -= closedposition;


            OnStart();






        }

    }
}
