I have often wondered whether all these guys make money and how. It seems such a struggle: Covel, Carstens, Nick Radge. Some of them have good ideas, some don't. Most don't provide a real time track record.
Or Ed Seykota - charming and intelligent but what a struggle peddling conferences and seminars.
The best money I have made trading has come from flipping IPOs which is or was virtually risk free, never a losing month etc. Everything else is disappointing by comparison. Hence my ignorant fascination with other schemes such as HFT where the die are also loaded in your favour.
