Sounds simple enough, but if it were that way, there would be many more people making money in forex. A method can produce both winners and losers in forex. If you have the same method, but a different risk management, different trade management, you can go from hero to zero very quickly.
I think that even if ICT were to map out exactly what he was trading - he has multiple concepts - people would blindly follow, and most of those would quite possibly fail as they are so focussed on ICT’s entry and not necessarily the whole package, being entry, management and risk. A persons psychology is also very important to help manage that trade.
