    Hi Mark,

     

    First of all, I take this opportunity to say thank you for this great tool and give you my encourage to carry on with your work. I bought a pro licence of analyzer and this version is great as well. Just a small request, could you please add the Calmar Ratio to the statistic? It’s a good measure of performance that most of us use.

     

    On the other hand, keep on with portfolio master tool. I believe this feature will rock!

     

    Thanks again!

     

    Regards

     

    ie: I added this topic here cos I couldn’t do it in analyzer section (add topic button is not enabled)

    Hello,

     

    I’ll look at it, I’d like to make it as an article – a sample how to extend the program and add your own statistical value.

    It will take me some time though, I’m on vacation whole next week. But it should be ready with final version of EA Analyzer 4.

    There’s loads of these measures:

    http://www.quantshare.com/item-1450-megan-ratio-maximum-exponential-growth-annualized

    https://www.evestment.com/resources/investment-statistics-guide/omega-ratio

     

    Not sure which one is important or that interesting, so implement one as a snippet in SQ4 and hopefully we can add others as people ask for them.

    Hi Mike,
     
    Thanks for that. It would be nice such an article because some of us are programmers too and maybe we can help with this type of requests if we would have a guide to do it. Regarding ratios, there a lot of different measures but Calmar ratio and specially VaR (Value at risk) are the most commonly used. Regarding Var, it would be nice if it will be present it final version as well but I understand this would be difficult but I think it’s something that most of us are looking for to buy a tool like Ea Analizer (Not me, I already bought it :-)).
     
    On the other hand, I am really looking forward to have the final version in my hands to see genetic portfolio builder Mike. You really don’t imagine what can I do with a tool like that… 
     
    Btw, enjoy your holidays!!

    Hi Mark,

     

    Any chance of an article on extending QA4 with new ways of ranking the Portfolio Master, so that we can create custom fitness functions?  For example how to combine calculations such as stability, profit factor and RT/DD into a ranking function?

     

    Thanks,

    Mikey . Again. Correct me if im wrong.

     

    You can set your fitness very easy 

     

      @Override
       public double computeFitness(SQResultsGroup resultsGroup) throws Exception {
          SQStats stats = resultsGroup.getResult(SQConst.SYMBOL_PORTFOLIO).getStats(SQConst.DIRECTION_ALL, SQConst.PL_IN_MONEY, SQConst.KEY_SAMPLE_ALL);
     
          double stability = stats.getDouble(StatsConst.STABILITY);
          double profitfactor  = stats.getDouble(StatsConst.PROFIT_FACTOR);
          double fitness  = stability*profitfactor;
          
         
          
          return fitness;
     
    Dont forget to create new stat value for confirmation ….

    Hi good afternoon

    By following the instructions you have provided in this posted I do not know yet why I am getting a compilation error in line 36 and column 25 which it states illegal character “\ufffd” and as a result it states that the compilation failed (i.e. screen shot attached)

    How should I proceed?

    Thank you in advanced for your prompt response

    Hi, can you attach the Java code (zipped) or send to support@strategyquant.com? I can check
