Aberration Bands Indicator Explained

Aberration is a classic 1990s breakout system distilled into bands: a simple average of typical price with ATR-based rails above and below. Its author traded the rails' breakouts across dozens of futures markets — the definition of a robust, unglamorous channel system.

How It Works

• Middle = SMA of typical price (HLC3); rails = middle ± ATR multiple.
• A close beyond a rail signals abnormal directional energy.
• Re-entry to the middle line marks the trade's natural exit.

How to Trade It

The original rules are refreshingly simple: buy the close above the upper rail, exit at the middle line; mirror for shorts. It's a portfolio strategy by design — expect losing chops on one symbol to be paid for by runners on another.

Building It in Setup.Cash

Add Aberration Bands in the strategy builder — the length input controls its sensitivity — and use its value in any entry, exit, or filter condition. You can also combine it with other tools in the Indicators Lab or via the AI indicator generator. Compare with Keltner Channels, the same geometry with different defaults. For the full category overview, see the volatility & statistics library guide.

Volatility indicators qualify trades rather than generate them — backtest your system with and without this filter and compare the drawdowns.
