Great article. My take is that Trading is SURELY gambling if you don't know what you are doing and are not trading using a proven, statistical edge - a method of trading that you have proven to yourself works over time. Having a winning edge of 40% is good enough to make money trading. Sound weird? It isn't if you take sound money management into the whole equation. That basically amounts to loosing less than what you win. The Holy Grail of trading is truly the Money Management aspects!
Hope this helps someone! Cheers
