ATOM Choppiness Zone
- Indicateurs
- Version: 1.20
ATOM Choppiness Zone is an advanced volatility filter designed to eliminate market noise and instantly reveal whether the market is ranging or trending. Based on the classical Choppiness Index formula developed by E.W. Dreiss, this tool converts complex mathematical calculations into a clean, color-coded visual histogram.
The Mathematics & Formula
The indicator measures market efficiency using fractal dimension logic. It calculates the ratio between the total True Range over $N$ periods and the high-low range of the same period:
Where:
-
$\text{TR}_i$: True Range for period $i$
-
$\text{MaxHigh}$ & $\text{MinLow}$: Extreme price points over the $N$ lookback period
-
$N$: Period setting (Default = 14)
How to Trade with Color Zones
Instead of watching a single line cross numerical levels, ATOM Choppiness Zone instantly categorizes market states into three actionable color zones:
-
Red Zone ($\ge 61.8$) — Choppy / Consolidation
-
Market State: High chaos, sideways movement, low directional efficiency.
-
Action: Avoid Trend Following. Do not trade breakout signals as false breakouts are frequent. Stay neutral or run mean-reversion strategies.
-
-
Grey Zone ($38.2 - 61.8$) — Transition Phase
-
Market State: Market is building energy and preparing for potential directional expansion.
-
Action: Prepare Watchlist. Monitor key support/resistance levels and wait for a color shift before taking action.
-
-
Green Zone ($\le 38.2$) — Strong Trending Phase
