Yea, good traders don't waste time on BS, and they teach themselves how to sniff it out. Most of these guys would fail a simple quiz on basic financial concepts. It's challenging. Honestly, I'm looking for the same thing as you. But, not sure what to do about it. The guys on these forums that obviously know their stuff are so few and far between. But, it really helped me when I got stuck and needed some 'next level' type of hints/suggestions. For me it was learning
1) Cross Hedging
2) Capital Efficient Strategies
3) Actual useful fundamental analysis
4) Being sure that you know which stuff is a dead end
5) Knowing ALL of the basics of trading
6) Math/Stats and programming ability
Most people are not at this level and when they can't speak intelligently about these topics it's a dead giveaway.
