Basic issue - How to get access to Price Series in multiple classes?

[debleded]

Hello everybody,

i want to use multiple classes in my strategy. Unfortunately i´m not able to use Price Series like High[], Low[], Open[] and close.

Here is an basic example for my problem:

public class Thisismystrategy : Strategy
     {
     CompareClass CC1 = new CompareClass();

     CC1.CompareWithHigh(10, 123,12);

     // Now i have access in my main class / strategy to following values
     // CC1.ValueIsHigherThanHighs
     // CC1.LastBarWhatIsHigherThanValue
     // CC1.HighOfThisBar     
    }


public class CompareClass : Strategy
     {
     private int i;

     public bool       ValueIsHigherThanHighs                = false
     public int          LastBarWhatIsHigherThanValue     = 0;
     public double    HighOfThisBar                              = 0; 

     public void CompareWithHigh (int AmountofBars, double PredefinedValue)
     {
     for(i = 1; i <= AmountofBars; i ++)
           {
            if(High[i] > PredefinedValue)
                   {
                   ValueIsHigherThanHighs            = false;
                   LastBarWhatIsHigherThanValue = i;
                   HighOfThisBar                          = High[i];

                   break;
                   }

           if(i == AmountofBars)
                  {
                   ValueIsHigherThanHighs = true;

                   break;
                   }
            }
        }
  }

It seems like CompareClass has no access to Price Series like the High[] in this case. How can i solve this problem?

Hi debleded, thanks for posting.

Your custom class needs the StrategyBase context to access the price series from the strategy. E.g.

public class CompareClass : Strategy
{
    private StrategyBase StrategyContext;

   CompareClass(StrategyBase _sb)
    {
        StrategyContext = _sb;
    }

    public double ReturnClose()
    {
        return StrategyContext.High[0];
    }
}

//from the Strategy:

new CompareClass(this); //passing in the StrategyBase context.

I also discuss including the class as a partial class here:
