William Blau's Ergodic True Strength Index (Ergodic TSI)

The Ergodic TSI is a double smoothed true strength index with a signal line. It is intended to act like a stochastic indicator without the 'compression' often seen with stochastics at extremes. As a result, it helps to register long trends.

The only change made to the indicator is the signal line, Blau said to use another EMA of the Ergodic TSI to generate a signal line, but this entry is late so I've changed it to the Ergodic TSI one period back.

For NNFX traders this is a PRIMARY CONFIRMATION indicator.
