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.
