Indicator Formula

Technical Details — SMI Ergodic Indicator (SMIErgodic)

Section titled “Technical Details — SMI Ergodic Indicator (SMIErgodic)”

The SMI Ergodic Indicator calculation produces a n unbounded oscillator measuring momentum.


Mathematical Derivation

Purpose: Derive the SMI Ergodic Indicator value.

See the SMI Ergodic Indicator formula derivation in technical references.

Where:

  • Period parameters control lookback sensitivity

What This Measures: Momentum strength and direction



Compact Formula Summary

Refer to SMI Ergodic Indicator formula for compact notation.

Defaults: Fast Period = 5 bars, Slow Period = 20 bars


Complete Calculation Example

See the SMI Ergodic Indicator technical documentation for worked calculation examples.


Key Takeaways from the Example
  1. Period sensitivity: Shorter periods = more signals, longer = smoother
  2. Threshold selection: Adjust based on asset volatility
  3. Signal line: Smoothed version for crossover timing
