Personally, I don't believe the markets are random. Why?...because the markets are made by people and people are predictable. I don't believe every trade has a 33% chance of being successful. Here's a quote from Trader Vic on an observation he made concerning the S&P open. "If there is a gap, and it is going to reverse, it will do so 10 to 15 minutes after the opening 95 percent of the time. Please believe me on the odds, they are real."

On the contrary: 33x0.5x100=1650 67x1x100=6700 ------------------------ Profit = +5050 Not bad, not bad at all!
