using System.Text;
using System.Drawing;
using WealthLab;
using WealthLab.Indicators;

namespace WealthLab.Strategies
{
	public class AtPriceDemo : WealthScript
	{
		protected override void Execute()
		{	
			// initialize your average series however you like		
			DataSeries avgSer = 0.5 * Open + 0.5 * Close;
			
			/* In the trading loop here's the buy signal that uses your peeking data.  
			   It won't create an Alert because they're peeking results.  Not a tradeable script! */
			for(int bar = 1; bar < Bars.Count; bar++)
			{
				if (IsLastPositionActive)
				{
					if( true )	// some condition to exit at the average price this month 
						this.ExitAtPrice(Bars, bar, LastPosition, avgSer[bar], "Out");
				}
				else
				{
					if( true )	// some condition to buy at the average price this month 
						this.EnterAtPrice(Bars, bar, avgSer[bar], PositionType.Long, "In");
				}
			}
			
		}
	}
}
