I am reading the book Trading Systems: A New Approach to System Development and Portfolio Optimisation by Emilio Tomasini an I'm trying to recreate (in NT) the steps they take in designing and testing systems.
They talk about the importance of "stability and robustness of input parameters" when it comes to optimizing. For instance if you optimize on MA period and the number 17 give you very good results but neighboring numbers (16 and 18-19 for example) are not so good, then you have a spike and even though 17 is best profit it isn't robust. Perhaps 6-10 is a bit lower profit but more equal then you would pick say 8 for a good tradeoff profit/robustness.
In NT how do you check this easy? In the Optimizer tab in the analyzer it's doable visually if you have limited inputs and not so many saved results lines. But it can quickly become a mess and overview is hard. Exporting all the individual results to Excel for further work seems tedious and not a good way to go either.
They use diagrams or Rina 3D smartview and it looks very good for this but I don't suppose that program is usable with NT in any way? (afaik it's part of Tradestation now)
But any suggestions on how to visualize this like on the picture below would be appreciated. I guess the visual part isn't crucial but help on knowing if my optimized parameter input results is "stable"
