# Horns Pattern Identifier

Scans the chart for horn tops and bottoms (the twin-spike reversal formations from Bulkowski's chart-pattern research) in both regular and inverted form. Each detection is drawn with its confirmation level and a measured take-profit target, and a bullish or bearish label prints the moment price breaks confirmation. A focused scanner for reversal traders.

**Horns Pattern Identifier** automates the detection of regular and inverted horn patterns and plots the two levels that make them tradeable: a confirmation line and a take-profit target derived from established pattern measurement rules. Horns belong to the family of [rare reversal patterns](https://www.luxalgo.com/library/concept/rare-reversal-patterns/) cataloged in Bulkowski's chart-pattern research: low-frequency formations built from twin price spikes that most eyes skip straight past, which is exactly why automated detection earns its keep.

## How to Trade the Horns Pattern Identifier?

- **The connecting line**: joins the two horns of a detected pattern, marking the formation itself on the chart.
- **Dotted confirmation level**: nothing is signaled until price breaches this line. When it does, a label prints the bias, bullish or bearish.
- **Dashed take-profit line**: the measured objective for the confirmed pattern, giving each detection a predefined target rather than an open-ended hope.

The confirmation-first design is the point. Because horns are subtle and easy to misjudge by eye, the indicator withholds its bullish or bearish call until price actually commits through the confirmation level, so a formation on its own is never treated as a signal.

## Horns Pattern Identifier Settings

- **Threshold**: the maximum slope allowed for the line connecting the two horns. Higher values accept steeper, more irregular formations and detect more patterns; lower values keep only clean, level horns at the cost of fewer detections.

## Frequently Asked Questions

### What is a horn pattern?

A reversal formation defined by two pronounced price spikes: horn tops form at highs and lean bearish once confirmed, horn bottoms form at lows and lean bullish. They are rare next to everyday candlestick signals, which is why a dedicated detector beats manual scanning.

### How are the confirmation and take-profit levels chosen?

Both follow Bulkowski's measurement rules for the pattern, applied automatically at detection time. The label only appears once price breaches the confirmation level, so the levels are fixed before any signal fires.

### Where can I get the indicator, and what pairs well with it?

It is free to use via the LuxAlgo Library. If compact reversal formations are your focus, the [Three-Bar Reversal Pattern](https://www.luxalgo.com/library/indicator/three-bar-reversal-pattern/) covers the faster, more frequent end of the same spectrum. You can also copy the source code from this page and run it anywhere Pine Script® runs.
