Auto Channel Detector

Channel Detector — Automatic Price Channel Identification

Channel Detector is an original TradingView indicator designed to systematically identify and visualize price channels using objective market structure logic. Instead of relying on manually drawn trendlines, the script analyzes structural swing highs and lows to detect sustained, parallel price movement and dynamically construct price channels as the market evolves.

The indicator determines channel validity by confirming aligned swing points that define both an upper and lower boundary. Once a channel is established, it plots:

A channel high based on validated swing resistance

A channel low based on validated swing support

A midline representing the statistical equilibrium of the channel

This midpoint is useful for evaluating mean reversion, momentum continuation, and reaction zones within the channel.

By continuously evaluating new price data, Channel Detector adapts to changing conditions and highlights both trending environments and controlled consolidations. Rising channels, falling channels, and horizontal structures are all detected using the same consistent logic, allowing traders to compare market behavior across different symbols and timeframes without subjective bias.

How traders can use this indicator

Identify structured trends and avoid trading against established channel direction

Anticipate potential breakout areas when price approaches channel boundaries

Use the midline as a dynamic area for pullbacks, reactions, or trade management

Add objective structure to discretionary price-action analysis

The indicator includes multiple customization options, allowing users to control line styles, colors, and visibility so the output remains clean and readable on any chart layout.

Channel Detector is intended for traders who value clarity, repeatable structure, and rule-based interpretation of price movement rather than manually drawn or purely subjective channels.
