New condition to Stochastic

Hi, 

please help me add a new condition to this indicator. I would like the arrow to form if the conditions that are present are met, plus one more - when the candle closes below /above the set average EMA.

        [Parameter("K Periods", DefaultValue = 14)]
        public int kPeriods { get; set; }

        [Parameter("K Slowing", DefaultValue = 3)]
        public int kSlowing { get; set; }

        [Parameter("D Periods", DefaultValue = 3)]
        public int dPeriods { get; set; }

        [Parameter("UP Level", DefaultValue = 80)]
        public int Up_Level { get; set; }

        [Parameter("Down Level", DefaultValue = 20)]
        public int Down_Level { get; set; }

        [Parameter("MA Type", DefaultValue = MovingAverageType.Simple)]
        public MovingAverageType maType { get; set; }

        {
            // Initialize and create nested indicators
            _stochastic = Indicators.StochasticOscillator(kPeriods, kSlowing, dPeriods, maType);

                }

            }

            //goldencloss
            if (_stochastic.PercentK.Last(2) < _stochastic.PercentD.Last(2) && _stochastic.PercentK.Last(1) > _stochastic.PercentD.Last(1))

                }

            }
