Method Details

reset

public void reset()

Specified by:

reset in interface Resettable

Overrides:

reset in class AbstractDecorableIncrementalRTIndicator

nextValue

protected double nextValue(double prevValue,
 double newValue)

Computes the Stochastic RSI using the formula: StochRSI = 100 * (RSI - minRSI) / (maxRSI - minRSI). newValue is already the freshly-computed RSI for this tick — the decorated chain (AbstractDecorableIncrementalRTIndicator.update(double)) runs the wrapped RSI indicator before this method is ever reached, so reading getValue() instead would read this indicator's own previous StochRSI output, not RSI (finding T3.3). Tracks rolling max/min RSI over the configured period. Returns 0 when the numerator or denominator is zero (flat RSI range).

Overrides:

nextValue in class AbstractDecorableIncrementalRTIndicator

Parameters:

prevValue - unused

newValue - the RSI value for this tick

Returns:

StochRSI value in the range [0, 100]

toString

protected com.google.common.base.MoreObjects.ToStringHelper toString(com.google.common.base.MoreObjects.ToStringHelper ts)

Overrides:

toString in class AbstractRTIndicator
