What Subscribers Are Saying
'Within days of subscribing to the YXI Commodities service, it had already paid for itself many times over. Every time I've second-guessed the signals or tried to outsmart the algorithm, I've left money on the table. Now I follow it mechanically, and I save time, trade with less stress, and sleep better at night. After reviewing the verified track record and experiencing the results firsthand, this is easily one of the best investment subscriptions I've ever made.'
'I recommend this service. The best part about the service isn't just the solid returns—it's the peace of mind. I follow their rotation model and don't second-guess my decisions. The algorithm does the heavy lifting, and it's worked out very well for me. Simple, effective, and profitable.'
'I joined YXI Commodities service about two weeks ago and I have already made more than the cost of the annual subscription. I like this service because I can purchase these commodities on pullbacks when the signal turns risk on and just watch the signal and sell when it turns risk off. It's refreshing to have a system this simple that makes money and I have to spend very little time with it!'

'Yimin Xu’s YX Insights service is profound. His deep insight into macro context for equities and crypto - as well as his multivalent and diligent assessment of trends, opportunities and risks, are incredibly timely and well-reasoned. I especially appreciate that he has a robust machine learning approach, but isn’t a slave to it. He regularly gives a seasoned evaluation that combines the technicals, the fundamentals, as well as the digital signals – with an appropriate concern for risk management. '
