Example

This example illustrates how to use the Input function to manually specify several symbols and find the DataSets they can be found in:

Example using C# extension methods + Legacy syntax (commented out):


using System;
using System.Windows.Forms;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using WealthLab;

namespace WealthLab.Strategies
{
	public class SearchForClickedSymbol : WealthScript
	{
		protected override void Execute()
		{
			ClearDebug();
			DataSourceManager dm = new WealthLab.DataSourceManager();
			dm.RootPath = Application.UserAppDataPath +  @"\Data\";

			string s = string.Empty;
			string[] symbols = this.Input().ToUpper().Split(',', ';', ' ');
			//string[] symbols = Community.Components.Utility.Input().ToUpper().Split(',', ';', ' ');
			
			foreach( string sym in symbols )
				s += String.Concat( sym, "," );
			PrintDebug("Searching for " + s + "..." );
			
			foreach(DataSource ds in dm.DataSources)
			{
				foreach (string str in symbols)
					if (ds.Symbols.Contains(str))					
						PrintDebug( "Found " + str + " in " + ds.Name );
			}
		}
	}
