Readings above 80 indicate the asset is overbought, while readings below 20 indicate it is oversold.

%K and %D Crossover

A bullish signal occurs when %K crosses above %D below the 20 level; a bearish signal occurs when %K crosses below %D above the 80 level.

Divergence

Occurs when price makes a new high/low but the Stochastic fails to do so, signaling a potential trend reversal.

FAQ

What is the difference between Fast, Slow, and Full Stochastics?

Fast Stochastic is the raw calculation; Slow Stochastic applies a 3-day SMA to %K to reduce noise; Full Stochastic allows custom smoothing for both %K and %D.

Does the Stochastic Oscillator work best in ranging or trending markets?

It is most effective in sideways or ranging markets. In strong trends, it can stay in overbought/oversold territory for a long time, leading to false reversal signals.

How can I reduce false signals when using this indicator?

Only take trades in the direction of the long-term trend and wait for the indicator to move back inside the 20/80 boundaries before entering.
