" One of my favorite patterns is the tendency for the markets to move from relative lows to relative highs and vice versa every two to four days. This pattern is a function of human behavior. It takes several days of a market rallying before it looks really good. That’s when everyone wants to buy it, and that’s the time when the professionals, like myself, are selling. Conversely, when the market has been down for a few days, and everyone is bearish, that’s the time I like to be buying. "
