Stochastic Chart 理论，另外，公式我忘记了三，你google一哈！Stochastic Chart The theory behind the indicator is that prices tend to close near the upper end of a trading range during an uptrend. As the trend matures, there is a tendency for prices to close away from the higher end of the trading range. The reverse case applies for a downward market. The stochastic attempts to measure the points in a rising trend at which the closing prices tend to hover around the lows for the period. When the stochastic reaches the extreme of 100 or 0, it signals that a strong move may be under way.
