Want to define a Fitness function to evaluate ranking systems that reports (1yr + 3yr + 5yr) returns
Fitness = perf(close,250) + perf(close,750) + perf(close,1250);

But, how do i define 1-year return in Fitness function?
The portfolio variables in custom fitness functions in Simulator Custom Metrics are not available for the Ranking System Analyzer Custom Fitness IDE.

You can only use the existing metrics. Use CONTROL+SPACE after "Fitness = " to get a list of available metrics.

Which ones are existing avaialble metrics? Pl point me to these.
I don't see any - just see some Global, Internal, Bucket functions which aren't really fitness metrircs.

You need to use the "Buckets" class.
Click on "Help" at the bottom for the definition of the class and its properties.

Fitness = Buckets.Buckets[0].AnnualReturn; // Annual return of the first bucket
Fitness = Buckets.LastBucket.DetailsDate[0].AvgPerf; // Average performance of the first date in the last bucket

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
