You use 40% OOS in the Generator.
With that setting, the generator loads only the first 60% of the data series. Correspondingly, the strategy in the collection shows the stats and charts based on 60% of the data file.
When you click a strategy and load it in the Editor, you see the stats and chart based on the full data file.
You may try the following:
A) Remove the OOS setting, if you want the strategy collection to be calculated on the full data file.
B) Use the Multi Tester to recalculate the complete collection with the full file. To do it:
1. Save the generated collection;
2. Go to the Multi Tester;
3. Recalculate the collection.
Now you will have a new collection with the same strategies, but calculated against the full data file.
C) Instead of OOS, reduce the data range in Control Panel -> Data Horizon and generate strategies with out OOS. The effect will be the same, but the stats in the collection and on the Editor will match. Later, you can remove the limitations in Data Horizon.
