I don’t like to put the problem, and not make a proposal:
i agree with the concept of representative trading decisions, then I would maintain the current IA, but I would change the name to SIGNIFICANCE, or similar
i would create another IA, named EXPERIENCE, but related with the lenght of the trackrecord. For example, we would need 2-3 years to get the maximun score.
With this it would be giving value:
A) to the long trackrecord and their capacity to stand different periods of the market
B)to the systems that decide not trade or trade and cut the losses quickly… but not for trading or not, it is for maintaining alive in the market.
C) to the systems with longer trackrecord of 12 dperiod, that it should be valued
The lenght of trackrecord of every system should be checked with a minimun normal activity as it does in darwinia, and check no changes in the type of system, it should detect changes in the type of system, that today the IA doesn’t do, and somebody could create a new system in an old darwin and start with 10 exp
With these two IA could make an average or other, and maintain the current limitation of dscore.
