Kagi
Reversal-based charting ignoring time and volume
Overview
Kagi charting is a Japanese technical analysis method that creates a charting system based exclusively on price movement direction and magnitude, completely ignoring time. Lines continue in the same direction until price reverses by a predetermined amount (Kagi reversal threshold), at which point the line changes direction and shifts one column to the right.
The resulting chart shows distinct patterns: thin lines represent weak moves with price closing near the line start; thick lines represent strong moves with price closing far from the line start. This distinction makes trend strength immediately visible without requiring volume data or momentum oscillators. Kagi is excellent at identifying consolidation breaks and institutional accumulation/distribution.
Used by professional traders analyzing institutional activity, Kagi removes time bias and focuses purely on price action dynamics. It's particularly effective for identifying support/resistance levels and breaking down complex trending behavior into clear directional plays. Most useful on daily timeframes and longer.
Formula
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| Reversal % | Percent | 4.0% | Price must reverse by this % to change Kagi direction |
| Reversal Type | Selection | Percent | Reversal % of current price or fixed point amount |
| Display Dots | Boolean | True | Show reversal dots at Kagi turning points |
Common Use Cases
1. Consolidation Breakouts
Kagi clearly shows consolidation patterns; thick lines breaking out of consolidation signal strength. Time-independent clarity.
2. Trend Direction Confirmation
Clear trending vs choppy market identification. Thin lines indicate indecision; thick lines show conviction.
3. Support/Resistance Levels
Kagi turning points often coincide with significant support/resistance. Prior Kagi reversals project future S/R zones.
4. Institutional Activity Tracking
Line thickness reveals absorption levels. Thin lines after strong moves indicate resistance; thick lines show conviction continuation.
Advantages & Limitations
✓ Advantages
- Time-Independent: Removes time bias inherent in candlesticks; shows pure price action.
- Trend Clarity: Consolidations compress into clear patterns; trends extend without noise.
- Institutional Mapping: Line thickness reveals strength vs weakness of moves, indicating institutional participation.
- Unique Perspective: Shows insights hidden in candlesticks; reveals hidden support/resistance.
! Limitations
- Parameter Sensitivity: Reversal % significantly changes results; requires calibration for each market.
- Steep Learning Curve: Non-standard charting requires practice to interpret correctly vs standard candles.
- Not Real Price Levels: Kagi levels don't reflect actual prices for exact stop/entry placement.
- Whipsaws Possible: Small reversal % can cause frequent false signals in choppy markets.
Tips & Best Practices
⚡ Calibrate Reversal %
Start with 3-5% for stocks/crypto, 2-4% for highly liquid forex. Test different values; lower % detects more reversals but creates noise.
📊 Combine with Standard Candles
Use Kagi for trend identification and reversal levels, but confirm entries/exits on standard candlesticks to get exact prices.
🔄 Read Thickness Changes
Thin line after thick line = weakness/absorption. Thick line after thin line = breakout strength. Thickness transitions signal turning points.
⚠️ Use on Daily+ Only
Kagi works best on daily and longer timeframes where consolidations are meaningful. Intraday Kagi often creates excessive noise.
Example Strategy
1. Setup: Daily Kagi Chart
Display daily Kagi with 4% reversal %. Identify current trend direction and prior Kagi reversal points (support/resistance).
2. Entry: Thick Line After Thin Line
Buy when Kagi transitions from thin to thick line in uptrend direction. Confirm on standard candlestick with volume on breakout.
3. Stop Loss: Kagi Reversal Point
Set stop loss beyond prior Kagi reversal on standard candlestick chart. If Kagi reverses against position, system is broken—exit immediately.
4. Target: Prior Kagi High or Thin Line Emergence
Exit at prior significant Kagi reversal (prior spike high) or when Kagi transitions to thin line (weakness signal). Trail stop above reversals.
