The highs and lows of the market can only be confirmed once they are established; this is the iron law of the market. No one truly knows in advance. Many people like to predict and guess the top and bottom ahead of time, but the results often backfire. The smartest approach is to wait until the price actually moves, then judge and act based on the actual trend. Don't fight the market blindly, and don't make reckless predictions. Let the market speak for itself.
