/**
 * The triple exponential average (TRIX) indicator is an oscillator used
 * to identify oversold and overbought markets, and it can also be used as
 * a momentum indicator. Like many oscillators, TRIX oscillates around a
 * zero line. When it is used as an oscillator, a positive value indicates an
 * overbought market while a negative value indicates an oversold market.
 * When TRIX is used as a momentum indicator, a positive value suggests
 * momentum is increasing while a negative value suggests momentum is
 * decreasing. Many analysts believe that when the TRIX crosses above the zero
 * line it gives a buy signal, and when it closes below the zero line, it gives
 * a sell signal. Also, divergences between price and TRIX can indicate
 * significant turning points in the market. TRIX calculates a triple
 * exponential moving average of the log of the price input over the period of
 * time specified by the length input for the current bar. The current bar's
 * value is subtracted by the previous bar's value. This prevents cycles that
 * are shorter than the period defined by length input from being considered by
 * the indicator.
