Can anyone advise how we would go about closing open trades in a direction, if the trend changes direction?
Setting a stop loss can be too restrictive so was trying to use the following but get errors:

 ClosePosition(TradeType.Sell); or  ClosePosition(shortSignal);

Error CS1502: The best overloaded method match for 'cAlgo.API.Robot.ClosePosition(cAlgo.API.Position)' has some invalid arguments

Error CS1503: Argument 1: cannot convert from 'cAlgo.API.TradeType' to 'cAlgo.API.Position'

Im getting stuck with the code trying to simply close any open trades as per below.....

        protected override void OnBar()
        {

            index = Bars.ClosePrices.Count - 2;

            if (ExitOnOppositeSignal && closeSignal)
                ClosePosition(currentPosition);

            //if (!inPosition)
            {

                if (EnterOnSyncSignalOnly)
                {

                    if (localTendencyWasShort && globalTendencyWasShort && localTendencyIsLong && globalTendencyIsLong)
                    {
                        EnterInPosition(TradeType.Buy);

ClosePosition(TradeType.Sell); or  ClosePosition(shortSignal);
                    }
                    else if (localTendencyWasLong && globalTendencyWasLong && localTendencyIsShort && globalTendencyIsShort)
                    {
                        EnterInPosition(TradeType.Sell);

ClosePosition(TradeType.Buy); or  ClosePosition(longSignal);
                    }

                }
                else
                {

                    if (shortSignal)
                    {
                        EnterInPosition(TradeType.Sell);

ClosePosition(TradeType.Buy); or  ClosePosition(longSignal);
                    }
                    else if (longSignal)
                    {
                        EnterInPosition(TradeType.Buy);

ClosePosition(TradeType.Sell); or  ClosePosition(shortSignal);
                    }
