Indicator Formula

Technical Details — Vortex Indicator (VI)

Section titled “Technical Details — Vortex Indicator (VI)”

Overview

Section titled “Overview”

The Vortex Indicator calculation produces a bounded oscillator measuring momentum.

Mathematical Derivation

Step 1 — Calculate VI

Section titled “Step 1 — Calculate VI”

Purpose: Derive the Vortex Indicator value.

See the Vortex Indicator formula derivation in technical references.

Where:

  • Period parameters control lookback sensitivity

What This Measures: Momentum strength and direction

Compact Formula Summary

Refer to Vortex Indicator formula for compact notation.

Defaults: Period = 14 bars

Complete Calculation Example

See the Vortex 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
