Great!
I think the issue with the methodology you are proposing to study the quality of MA´s system suffers from the fact, that the results are influenced by the trading skills of individuals. So at the end you will still not now if the results are due to Socrates or do the superb trading skills. Everyday in the markets there are plenty of winners that are using their own systems. Does technical analysis work ? Sure! but there are a lot of traders loosing money with that system. Is that a fault of technical analysis ?
The accuracy of Socrates can be only tested against the predictions the system is generating and not for specifics trades that are on the responsibility of individuals. It predicted a high in Nasdaq in May. We have a high in May so far. Bitcoin reversals predicted an uptrend in Bitcoin: we are having a bitcoin uptrend. No weekly bearish reversals have been elected so far. And the next high / low is supposed to be in June. We will see.
Between May first and today the system did not predict any specific weekly direction for Nasdaq as no weekly reversals have been elected (also not any monthly, daily I am not following). This is exactly what is happening now. If reversals are elected tomorrow , I will post it here and then we can see the results one week after (where we should consider that reversals act similar as support / resistance levels) So far, I can not complain in any aspect about the prediction of the system as long as I am following it.
