Boris Schlossberg and Kathy Lien are both well known FX experts who often can be seen in CNBC or CME commentaries. They sell signal and education services to retail traders. Anyone tried their services? My question always narrows down to "why they do this if they are so successful traders?" Warren Buffet doesn't sell signal or education services. Why Boris and Kathy do this on the other hand? My common sense is if I am a so successful trader, I would work with Goldman Sachs or big hedge funds rather than work with retailers. Any comments?
