Optimized Alligator Engine (EMA/HMA/SMMA Switchable)

he classic Williams Alligator is a legendary trend-following indicator, but it has a significant drawback in modern, high-volatility markets: Lag. Its reliance on SMMA (Smoothed Moving Average) often results in late entries and even later exits, causing traders to miss the meat of a move or give back profits during a reversal.
This script is a complete overhaul of the classic model, designed specifically for Price Action (PA) traders who operate on 4H and Daily timeframes. It injects modern moving average algorithms into the Alligator’s core logic.
🚀 Key Features:
1. Multi-Engine Support: Toggle between three different moving average types directly from the settings: • SMMA (Classic): For those who prefer the traditional, conservative Williams approach.
• EMA (Modern): A balanced approach that responds faster to recent price action than the classic model.
• HMA (Zero-Lag): Powered by the Hull Moving Average, this mode provides the fastest response time, ideal for capturing explosive trends in crypto and high-volatility assets.
2. Pine Script v6 Optimized: Built on the latest version of Pine Script for maximum execution efficiency and chart stability.
3. Visual Continuity: Retains the iconic Blue (Jaw), Red (Teeth), and Green (Lips) color scheme to ensure a seamless transition for veteran traders.
💡 Trading Strategy & Tips:
• Filter, Don't Just Follow: Use the Alligator to identify "Sleeping" (entwined lines) vs. "Awake" (fanned-out lines) phases.
• The 4H Sweet Spot: On 4H charts, switching to HMA mode can signal trend exhaustion 2-3 candles earlier than the default version, allowing for tighter stop-losses and more precise exits.
• PA Integration: Combine this with Fractals and Volume Spread Analysis (VSA). When the Alligator's mouth is wide open and you see a high-volume rejection candle (like a Pin Bar), it’s a high-probability signal to scale out.
Settings Guide:
• MA Type: Choose your engine (SMMA/EMA/HMA).
• Jaw/Teeth/Lips Length: Standard 13/8/5 periods.
• Offsets: Classic 8/5/3 displacement.
Enjoy the precision. Let the Alligator work for you, not against you.
