How to use DEMA

Hi, 

Can anyone how I can integrate the DEMA indicator (code shown below taken from cAlgo indicator examples) seamlessly into my strategy rules? I've just tried to paste it as it is into the current strategy rules and it comes up with the error "{ expected", or "A namespace cannot directly contain members such as fields or methods". Help much appreciated.

Regards

using System;

using cAlgo.API;

using cAlgo.API.Indicators;

namespace cAlgo.Indicators

{

[Indicator(IsOverlay = true, AccessRights = AccessRights.None)]

public class DEMA : Indicator

{

[Parameter()]

public DataSeries DataSource { get; set; }

[Output("DEMA", Color = Colors.Yellow)]

public IndicatorDataSeries dema { get; set; }

[Parameter(DefaultValue = 14)]

public int Period { get; set; }

private ExponentialMovingAverage ema;

private ExponentialMovingAverage ema2;

protected override void Initialize()

{

ema = Indicators.ExponentialMovingAverage(DataSource, Period);

//i need the correct DataSeries

ema2 = Indicators.ExponentialMovingAverage(ema.Result, Period);

}

public override void Calculate(int index)

{

dema[index] = (2 * ema.Result[index] - ema2.Result[index]);

}

}

}
