Dear Lim,
Glad to hear from you. Yes we have tried during th years many things but we stick to the Forex, and recently to the cryptocurrencies.
Much easier to findd the best Forex robot because it is ok to trade even 99 EAs(as I show in one of the courses) in one trading account.
We follow the performance on Demo account and after that we place the best Forex robot on a live, and by the best, I mean the one that is currently making profits.
