Hmm, If trading is all about luck when what's the difference between trading and gambling/betting, i think Luck can be considered as a minor part of your trade as, yup i do consider if you are lucky enough to choose or target a good asset it can increase the chances of your trades success. But if trading is completely about Luck then why are there so many patterns, strategies, risk management, and most importantly psychology?
All these terms together create a foolproof analysis in which traders spend the maximum of their time to shine their skills for better decision-making and trade execution.
