Nick Shawn trots out another client as proof of his expertise rather than publishing his own "results"???
It’s difficult to determine someone is best without applying his uttered strategies or ways of trading to the market and reap better gain.
Not quite sure exactly what you mean by his uttered strategies, and I doubt applying them will reap any gains. If you follow any of his videos since March, he has changed strategy from hedging to mean reversion, and now he plans to use all of them together, with a high leverage account. Let's see how that works. His sales pitch is basically claiming to be hugely profitable, and then directing people to his free Telegram where it is all documented. So, you must do the research yourself instead of him actually providing a broker statement; I mean how hard is that for him to do?
