5. Installation Instructions

To set up the Backtest visualizer c# library in cAlgo, please follow the following steps.

• Copy the downloaded .dll file into your cAlgo API folder : cAlgo\API

1. Launch cAlgo and open the Robot you want to backtest
2. Add the following directive
    using Scyware.BacktestPlayer; 
3. Add reference to the downloaded .dll c# library



4. Make sure the Robot has its access right set to AccessRights.FullAccess mode
   [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.FullAccess)]
   The FullAccess mode is needed to enable the UIPermission to be able to display the GUI of the visualizer
5. Decalre a BacktestVisualizer class field or property
   BacktestVisualizer visualizer;
6. Instantiate the BacktestVisualizer object in the OnStart() method of the Robot
   visualizer = new BacktestVisualizer(this);
7. Modify the OnStop() method of the Robot to call the OnStop() method of the visualizer as follows
   

   protected override void OnStop()
   {
      // ... any other existing code
      visualizer.OnStop();
   } 
   

8. A minimal robot code with backtest visualizer is illustrated in the following code snippet

   using System;
   using System.Linq;
   using cAlgo.API;
   using Scyware.BacktestPlayer;
   
   namespace cAlgo
   {
       [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.FullAccess)]
       public class Scyware_Backtest_Visualizer : Robot
       {
   
           BacktestVisualizer visualizer;
   
   
   
           protected override void OnStart()
           {
   
               visualizer = new BacktestVisualizer(this);
   
           }
   
   
           protected override void OnStop()
           {
               visualizer.OnStop();
   
           }
       }
   }
