All Implemented Interfaces:

Resettable, RTIndicator

public class TemaRTIndicator
extends AbstractRTIndicator

Triple Exponential Moving Average (TEMA) RTIndicator.

Computes TEMA by combining three cascaded EMAs to reduce lag while maintaining smoothness.

Formula: TEMA = 3×EMA1 - 3×EMA2 + EMA3 where EMA1 = EMA(price), EMA2 = EMA(EMA1), EMA3 = EMA(EMA2).

Method Details

isReady

public boolean isReady()

Description copied from interface: RTIndicator

Returns whether this indicator has received enough data to produce meaningful values.

During the warmup period, RTIndicator.getValue() may return 0 or a partial estimate that should not be used for trading decisions. Once this method returns true, the indicator's output is statistically valid.

The default implementation returns true for backward compatibility. Indicators with warmup requirements should override this method.

For composite indicators (e.g. Bollinger Bands, MACD), readiness is determined by the slowest internal component.

Returns:

true if the indicator has completed its warmup period
