I have a history of questioning many of the resident gurus on the Board who teach elaborate systems which nobody (well, less than 10%) claim to even trade profitably. When I do so they get really mad at me instead of just proving their system (via Live Calls, or on the PnL Thread, or by posting their blotters on their own thread). If they did so, curiousity satisfied, I would be more than happy to STFU). So, why is that? Why do Gurus get mad when you ask for proof?
