Of course it’s easy! You just compare how much you’ve made, and how long you’ve stayed solvent, against the top 1% of traders. If you’ve already done just as well as the others, you’d in the top 1%. Otherwise, you aren’t.
There’s a fair amount of debate over how much data you need to evaluate whether a person is a consistently good trader, in my moderately-informed opinion a trader who does well over 2 years is significantly more likely to be lucky than skilled.
This object-level example is actually harder than it appears, performance of a fund or trader in one time period generally has very low correlation to the next, e.g. see this paper: https://www.researchgate.net/profile/David-Smith-256/publication/317605916_Evaluating_Hedge_Fund_Performance/links/5942df6faca2722db499cbce/Evaluating-Hedge-Fund-Performance.pdf

That’s why I said “how long you’ve stayed solvent.” Thanks for bringing in a more nuanced statement of the argument + source.
