As their name imply, indicators show a possible direction. I found out that MACD works well on an intraday basis. Particularly when a stock tanks MACD indicates when it is ready to rebound. Not a completely safe bet but I would say it is accurate 75% of the time.
jturner,
You made money by shorting the cube. I am gonna make money by going long. Bought 500 shares today and will hold them for a while. This is the beginning of another bull market.
