Strategy errors

[2Look4me]

Brett/Matthew,

As always, thanks for your prompt replies and for the assistance every way you can. I know how to call on the indicator values, just that in this case there are certain limitations doing it that way. Therefore, the example code that Matthew provided is very helpful.

Hello,

Instead of calling the Stochastics' values to be used in a strategy, I would like to copy and paste the entire Stochastics script.

How do I get around the error in "Properties": The name "Value" does not exist in the current context?

Thanks in advance...

"Value" is a data series that is added when you use the Add() method for indicator plots.... this method does not work from a Strategy, so there is no Value series for you to use. You will have to replace it with your own custom data series.

Here is an example of the code used, where I replaced the public K and D value series with a private data series...I also attached an exported version

	public class StochStrategy : Strategy
	{
		#region Variables
		private int				periodD	= 7;	// SlowDperiod
		private int				periodK	= 14;	// Kperiod
		private int				smooth	= 3;	// SlowKperiod
		private DataSeries		den;
		private DataSeries		nom;
        private DataSeries      fastK;
		
		private DataSeries 		D;
		private DataSeries 		K;
		
		#endregion

		/// <summary>
		/// This method is used to configure the indicator and is called once before any bar data is loaded.
		/// </summary>
		protected override void Initialize()
		{
			den			= new DataSeries(this);
			nom			= new DataSeries(this);
            fastK       = new DataSeries(this);
			
			D 			= new DataSeries(this);
			K			= new DataSeries(this);
		}

		/// <summary>
		/// Calculates the indicator value(s) at the current index.
		/// </summary>
		protected override void OnBarUpdate()
		{
            nom.Set(Close[0] - MIN(Low, PeriodK)[0]);
            den.Set(MAX(High, PeriodK)[0] - MIN(Low, PeriodK)[0]);

            if (den[0].Compare(0, 0.000000000001) == 0)
                fastK.Set(CurrentBar == 0 ? 50 : fastK[1]);
            else
                fastK.Set(Math.Min(100, Math.Max(0, 100 * nom[0] / den[0])));

            // Slow %K == Fast %D
            K.Set(SMA(fastK, Smooth)[0]);
            D.Set(SMA(K, PeriodD)[0]);
			
			Print(K[0]);
        }

		#region Properties
		
		/// <summary>
		/// </summary>
		[Description("Numbers of bars used for moving average over K values")]
		[GridCategory("Parameters")]
		public int PeriodD
		{
			get { return periodD; }
			set { periodD = Math.Max(1, value); }
		}

		/// <summary>
		/// </summary>
		[Description("Numbers of bars used for calculating the K values")]
		[GridCategory("Parameters")]
		public int PeriodK
		{
			get { return periodK; }
			set { periodK = Math.Max(1, value); }
		}

		/// <summary>
		/// </summary>
		[Description("Number of bars for smoothing the slow K values")]
		[GridCategory("Parameters")]
		public int Smooth
		{
			get { return smooth; }
			set { smooth = Math.Max(1, value); }
		}
		#endregion
	}

I would not advise copy and pasting the stochastics code in to your strategy. You should call it like a regular indicator in the strategy. Why do you want to copy/paste vs call like normal indicator? If you do not know how to call it as normal (without copy/paste) then let me know I could furnish information to help you get started with that.
