Pivot Channel TrendLines [BigBeluga]

The Pivot Channel TrendLines [BigBeluga] is an advanced technical analysis indicator designed by BigBeluga to automatically map structural pivot points, project dynamic trendline channels, and track directional breakout signals directly on the chart. Traditional manual trendline drawing is often subjective and time-consuming, while standard indicators fail to account for slope progression and volatility filters. To solve this limitation, this script combines an automated pivot detection engine with ATR-filtered extension lines and real-time breakout triggers.

The indicator visualizes key market highs and lows, dotted projection channels, and directional signals. The core calculations identify confirmed pivot extremes using configurable lookback periods, compute slope values between successive pivots, and filter out insignificant structures using Average True Range thresholds. Customizable color palettes, line styles, and extension lengths allow traders to fine-tune the geometric mappings across various asset classes and timeframes.

The system operates through an integrated architecture where each component dynamically influences chart behavior:

1 — Automated Pivot Detection Engine

• Lookback Scanning: Evaluates bar ranges using user-defined lookback criteria to identify significant swing highs and lows.
• ATR Filtering: Compares successive pivot price differentials against Average True Range thresholds to ensure only meaningful structural shifts generate active channels.

2 — Dynamic Trendline Projection & Channels

• Confirmed Trendlines: Connects historical pivot points with solid boundary lines to map ongoing trend channels.
• Dotted Extensions: Projects sloping extension lines forward by a user-defined bar length to monitor future support and resistance interactions.

3 — Directional Breakout & Price Dash System

• Breakout Triggers: Monitors active extension lines in real time, plotting directional labels ("Up" or "Down") whenever price closes beyond expected threshold boundaries.
• Last Pivot Dashes: Renders customizable horizontal dashed or dotted lines alongside precise price level tags for the latest identified high and low pivots.
  

Apart from serving as an automated structural mapping tool, the indicator can be applied in several ways:

1. Identify Trend Channels: Follow the solid and dotted trendlines connecting major pivot highs and lows to track prevailing market direction and channel boundaries.
2. Catch Structural Breakouts: Monitor the chart for Up or Down directional labels indicating when price has successfully broken through active projected extension lines.
3. Track Recent Reference Prices: Use the last pivot price dashes to quickly reference key support and resistance boundaries established by the most recent market swings.

Why this implementation is unique:

• It automates complex pivot channel mapping and slope projections directly on the chart.
• Features integrated ATR volatility filters to eliminate insignificant structural noise.
• Fully optimized for high-performance rendering under Pine Script version 6 standards.
