All Implemented Interfaces:
Resettable, RTIndicator
public class TrixRTIndicator extends AbstractRTIndicator
TRIX (Triple Exponential Average) with O(1) per-tick computation. 
  EMA1 = EMA(close, periods)
  EMA2 = EMA(EMA1, periods)
  EMA3 = EMA(EMA2, periods)
  TRIX = (EMA3 - prevEMA3) / prevEMA3 * 100

Momentum oscillator that filters out insignificant price movements using triple smoothing. Positive = bullish, negative = bearish. Crossings of zero line are trade signals.

      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
