Supertrend + Fibonacci OTE Grid & Bands [BigBeluga]

🔵 OVERVIEW

The Supertrend + Fibonacci OTE Grid & Bands [BigBeluga] is an advanced technical analysis indicator designed by BigBeluga to combine trend-following Supertrend mechanics with dynamic Fibonacci retracement grids and volatility-based channel bands directly on the chart. Traditional Supertrend systems rely solely on stop lines, often missing optimal retracement zones (OTE) during trend pullbacks. To solve this limitation, this script integrates dual operating modes—anchored OTE grids that project Fibonacci levels across active trend swings, and continuous Fibonacci channel bands scaled by Average True Range (ATR).

The indicator visualizes trend direction, dynamic stop losses, shaded OTE zones, and proximity-highlighted grid levels. The core calculations track trend swings using customizable ATR lookbacks, compute proportional Fibonacci levels (0.0 to 1.0), and dynamically adjust line widths and colors when price approaches specific thresholds. Custom color palettes, bar/candle color toggles, and label configurations allow traders to fine-tune visual settings across various timeframes and asset classes.

🔵 HOW IT WORKS

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

1 — Supertrend Trend & Swing Engine

• Stop Loss Line & Fills: Computes volatility-scaled Supertrend lines using ATR parameters, plotting colored stop-loss streams with gradient area fills.
• Trend Extreme Tracking: Automatically tracks trend highs and lows upon trend direction flips to anchor structural Fibonacci calculations.

2 — Dual Fibonacci Modes (OTE Grid & Bands)

• OTE Grid Mode: Projects an anchored Fibonacci retracement grid (0.0, 0.236, 0.382, 0.500, 0.618, 0.705, 0.786, 1.000) across the active trend swing, complete with a shaded Optimal Trade Entry (OTE) zone between the 0.618 and 0.786 levels.
  
• Fibonacci Bands Mode: Plots continuous, ATR-scaled channel bands extending outward from the Supertrend line using proportional ratio offsets.
  

3 — Proximity Highlight & Styling Engine

• Price Proximity Detection: Measures distance between price and individual grid levels using ATR multipliers to dynamically highlight active levels with distinct colors and thicker line widths.
• Visual Customization: Supports bar and custom candle coloring by trend, adjustable line styles (Solid, Dotted, Dashed), and dynamic right-edge price labels.

🔵 HOW TO USE

Apart from serving as a comprehensive trend and retracement mapping tool, the indicator can be applied in several ways:

1. Follow Trend Momentum: Stay aligned with prevailing market direction by monitoring the Supertrend line color and trend-colored candles/bars.
   
2. Identify OTE Retracement Zones: In OTE Grid mode, monitor the shaded zone between the 0.618 and 0.786 Fibonacci levels for potential trend continuation entries during pullbacks.
   
3. Track Key Level Interactions: Watch for automatic color highlights and width changes on grid levels as price approaches critical Fibonacci thresholds.
   

🔵 SETTINGS

The indicator includes several customizable configuration groups to tailor calculations and visual styling to your trading style:

• General Settings: Select between OTE Grid and Fibonacci Bands modes, toggle right-edge price/ratio labels, choose grid line styles (Solid, Dotted, Dashed), adjust grid highlight distance thresholds via ATR multipliers, and enable dimming for non-OTE levels.
• Supertrend Parameters: Configure the ATR Period and Multiplier to adjust the sensitivity and distance of the core stop-loss line.
• Fibonacci Bands Parameters: Define the ATR period and outer band multiplier specifically used when operating in Fibonacci Bands mode.
• Main Styling & Colors: Set bullish and active price highlight colors, and toggle bar/candle coloring based on the active trend direction.
• Fibonacci Level Settings: Enable or disable individual Fibonacci ratios (0.000, 0.236, 0.382, 0.500, 0.618, 0.705, 0.786, 1.000) and customize their individual display colors.

🔵 NOTES

Why this implementation is unique:

• It merges classic Supertrend stop mechanics with both anchored OTE grids and continuous Fibonacci channel bands.
• Features dynamic price proximity highlighting and custom linefill engines optimized for Pine Script version 6.
• Provides extensive modular inputs for styling, level visibility, and operational mode switching.
