Kairi Trend Oscillator [T3][T69]

📌 Overview
The Kairi Trend Oscillator [T3][T69] is a Japanese-inspired hybrid oscillator combining Heikin-Ashi trend clarity with the Kairi (乖離率) indicator — a measure of price deviation from a moving average. This dual-layer system gives you both trend direction and trend strength/health, designed to highlight trend maturity and avoid overextended entries.

✨ Features

• Heikin-Ashi or normal candlestick input modes
  
• Multiple moving average options: SMA, EMA, DEMA, VWMA, and Kijun
  
• Visual color-coded trend zones: overbought, oversold, healthy, weak, and reversal conditions
  
• Full Kairi column plot with dynamic coloring
  
• Adaptive logic for trend detection (linear regression or Heikin-Ashi structure)
  
• Built-in reversal detection based on divergence between Kairi and trend direction
  

⚙️ How to Use

• Choose Candle Type: Select Heiken Ashi or Normal Candlesticks via the Candle Mode dropdown.
  
• Select Source: Choose open, high, low, or close as the input for Kairi computation.
  
• Set MA Type & Length: Configure the moving average mode and its length under Moving Average Settings.
  
• Interpret the Plot:
  
  • Green/Red bars: Show Kairi oscillator values above/below 0
    
  • Background color: Shows current trend (green = uptrend, red = downtrend)
    
  • Candle color overlays:
    
    • 🟩 Teal = Overextended Bulls
      
    • 🟥 Maroon = Overextended Bears
      
    • ✅ Green = Healthy Uptrend
      
    • 🔻 Red = Healthy Downtrend
      
    • 🟨 Light tones = Weak trends
      
    • 🔄 Blue/Fuchsia = Possible reversal detected
      

🔧 Configuration
Inputs:

• Candle Mode: Heiken Ashi or Normal Candle Sticks
  
• Source: Open, High, Low, Close
  
• MA Mode: SMA, EMA, DEMA, VWMA, or Kijun
  
• MA Length: Default is 29
  

🧪 Advanced Tips

• Use Heikin-Ashi mode for better trend smoothing.
  
• Kairi divergence (e.g., bullish Kairi in a downtrend) may signal upcoming reversal — watch for blue or fuchsia bars.
  
• Combine with momentum indicators (e.g. RSI or MACD) for confluence-based setups.
  
• For mean reversion strategies, fade extreme Kairi readings (> ±5%).
  

⚠️ Limitations

• Not suited for ranging markets without trend.
  
• Kairi extremes may remain elevated in strong trends — avoid early counter-trend entries.
  
• Reversal logic is not a confirmation signal; use with caution.
