While i do respect your trading knowledge...i have to really disagree with you here. Reason is...i have been arbing craigslist since i was 16 (currently 37)...had my dealers license at 18 going to auto auctions to flip vehicles...did the same with off road stuff when I got a bit older...then guns/ammo a little after that (technically didnt "arb" them as that would be illegal...i only traded to "improve my collection" of course).
on top of having a natural ability to trade physical goods successfully...i was professionally trained by Halliburton to sell multi million dollar Fluid jobs to operators. I am a very good salesman both from nature as well as nurture...and I have a very good eye for mispricing and potential value...
All of that ability has meant absolutely nothing when it comes to trading the financial markets. The main reasons: Trading completely eliminates the individuals innate sales ability...the market does not care how personable you are, how respectful or nice or likeable you are, how well written your sales listing is, your ability to communicate effectively, etc... Also completely eliminated is the ability/opportunity to improve the physical good (sweat equity) before selling. I bought a 5.0 fox body once for $200 because the engine shook terribly and it was dirty, new harmonic balancer and it ran like new, pull out the interior and clean thoroughly so it looks like a loved vehicle and boom, 10 bagger.
trading physical goods and trading financial markets have been complete opposites for me, unfortunately lol.
