Kairi Trend Oscillator [T3][T69]

1 042
📌 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.
