Stochastic Fast (STOCHF) 指标

The Stochastic Fast oscillator is a momentum indicator designed to indicate oversold and overbought market conditions. It shows the location of the close relative to the high-low range over a set number of periods. Normalizes price as a percentage between 0 and 100.
The Stochastic Fast generates two lines. The %K line and a moving average of the %K which is called %D.
The area above 80 indicates an overbought range, while the area below 20 is considered an oversold range.

A crossover signal occurs when the two lines cross in the overbought or oversold region. A sell signal occurs when a decreasing %K line crosses below the %D line in the overbought region. Conversely, a buy signal occurs when an increasing %K line crosses above the %D line in the oversold region.

Divergences form when a new high or low in price is not confirmed by the Stochastic Oscillator. A bullish divergence forms when price makes a lower low, but the Stochastic Oscillator forms a higher low. This indicates less downward momentum that could foreshadow a bullish reversal. A bearish divergence forms when price makes a higher high, but the Stochastic Oscillator forms a lower high. This shows less upward momentum that could foreshadow a bearish reversal.
