http://www.unifr.ch/econophysics/minority/game/ You win if you do the opposite of everyone else, ie if you pursue the minority strategy. Sort of like any parimutuel betting game.
I'll just quote my brother from another mother "There are countless institutions out there that have teams of smart people to analyze financial statements, do thorough market research, and investigate and scout out the competition; they consult economists who can offer advice on the bigger picture; the have dinosaurs with decades of experiences with the market, relationships with exchanges and brokers, computer algorithms to buy and sell securities with minimal impact, etc. Do you think you can go up against these institutions that have every advantage against you? Do you really think that youâve spotted an opportunity that one of the numerous analysts or the constantly scanning proprietary software programs hasnât picked up on?â¦Really? No offense, but who the F are you? Youâre a nobody, stop lying to yourself, you just canât compete. Sure, you can get lucky, but donât tell me youâve actually got any kind of talent for selecting stocks. And the silly thing is, the game isnât even about âselectingâ stocks, itâs so much more esoteric than that, but for argumentâs sake letâs keep it simple here." http://livinginvol.com/?p=97
This prediction game offers insufficient information to demonstrate any trading prowess in reality. But you win if you study the metrics of a market you want to trade and you apply a logical methodology to extract serial profits from that market. To operate such a methodology, you use a liquid and volatile market (eg CL,NG) which will offer you 2 advantages: plenty of points daily and the gyrations (ie swings) from which to extract substantial trading points (ie net profits) sequentially, open to close. You do this through the mechanism of buying the upmoves and selling the downmoves as they follow each other. And a tested and reliable methodology gives you the triggers for buying upmoves and selling downmoves as they follow each other.
