chanlun缠论 - 笔与中枢Overview The Chanlun (缠论) Strokes & Central Zones indicator is an advanced technical analysis tool based on Chinese Chan Theory (Chanlun Theory). It automatically identifies market structure through "strokes" (笔) and "central hubs" (中枢), providing traders with a systematic framework for understanding price movements, trend structure, and potential reversal zones. Theoretical Foundation Chan Theory is a sophisticated price action methodology that breaks down market movements into hierarchical structures: Local Extremes: Swing highs and lows identified through lookback periods Strokes (笔): Valid price movements between opposite extremes that meet specific criteria Central Hubs (中枢): Consolidation zones formed by overlapping strokes, representing key support/resistance areas Key Components 1. Local Extreme Detection Identifies swing highs and lows using a configurable lookback period (default: 5 bars) Only considers extremes within the specified calculation range Forms the foundation for stroke construction 2. Stroke (笔) Identification The indicator applies a multi-stage filtering process to identify valid strokes: Stage 1 - Extreme Consolidation: Merges consecutive extremes of the same type (high or low) Keeps only the most extreme value (highest high or lowest low) Stage 2 - Stroke Validation: Ensures minimum bar gap between strokes (default: 4 bars) Alternative validation: 2+ bars with >1% price change Eliminates noise and insignificant price movements Color Coding: White Lines: Regular up/down strokes Yellow Lines: Strokes that form part of a central hub Customizable width and colors for different stroke types 3. Central Hub (中枢) Formation A central hub forms when at least 3 consecutive strokes have overlapping price ranges: Formation Rules: Stroke 1: Stroke 2: Stroke 3: Hub Upper = MIN(High1, High2, High3) Hub Lower = MAX(Low1, Low2, Low3) Valid if: Hub Upper > Hub Lower Hub Extension: Subsequent strokes that overlap with the hub extend it Hub ends when a stroke no longer overlaps Creates rectangular zones on the chart Visual Representation: Green rectangular boxes: Mark the time and price range of each central hub Dashed extension lines: Show the latest hub boundaries extending to the right Price labels on axis: Display exact hub upper and lower boundary values 4. Extreme Point Markers (Optional) Red markers for tops (▼) Green markers for bottoms (▲) Marks every validated stroke extreme point Useful for detailed structure analysis 5. Information Table (Optional) Displays real-time statistics: Symbol name Current timeframe Lookback period setting Minimum gap setting Total stroke count Parameter Settings Performance Settings Max Bars to Calculate (3600): Limits historical calculation to improve performance Local Extreme Lookback Period (5): Bars used to identify swing highs/lows Min Gap Bars (4): Minimum bars required between valid strokes Display Settings Show Strokes: Toggle stroke line visibility Show Central Hub: Toggle hub box visibility Show Hub Extension Lines: Toggle dashed boundary lines Show Extreme Point Marks: Toggle top/bottom markers Show Info Table: Toggle statistics table Color Settings Full customization of: Up/down stroke colors and widths Hub stroke colors and widths Hub border and background colors Extension line colors Trading Applications Trend Structure Analysis Uptrend: Series of higher highs and higher lows connected by strokes Downtrend: Series of lower highs and lower lows connected by strokes Consolidation: Formation of central hubs indicating range-bound movement Support and Resistance Identification Central Hub Zones: Act as strong support/resistance areas Hub Upper Boundary: Resistance level in consolidation, support after breakout Hub Lower Boundary: Support level in consolidation, resistance after breakdown Price tends to react at these levels due to market structure memory Breakout Trading Bullish Breakout: Price closes above hub upper boundary Previous resistance becomes support Entry on retest of upper boundary Stop loss below hub zone Bearish Breakdown: Price closes below hub lower boundary Previous support becomes resistance Entry on retest of lower boundary Stop loss above hub zone Reversal Detection Hub Formation After Trend: Signals potential trend exhaustion Multiple Hub Levels: Create probability zones for reversals Stroke Count: Excessive strokes within hub suggest weakening momentum Position Management Use hub boundaries for stop loss placement Scale out positions at hub edges Re-enter on retests of broken hub levels Interpretation Guide Strong Trending Market Long, clear strokes with minimal overlap Few or no central hubs forming Strokes consistently in same direction Wide spacing between extremes Consolidating Market Multiple central hubs forming Short, overlapping strokes Yellow hub strokes dominate the chart Narrow price range Trend Transition Hub formation after extended trend Stroke direction changes frequently Hub boundaries being tested repeatedly Potential reversal zone Advanced Usage Techniques Multi-Timeframe Analysis Higher Timeframe: Identify major hub zones for overall market structure Lower Timeframe: Find precise entry points within larger structure Alignment: Trade when lower timeframe strokes align with higher timeframe hub breaks Hub Quality Assessment Wide Hubs: Strong consolidation, higher probability support/resistance Narrow Hubs: Weak consolidation, may break easily Extended Hubs: More strokes = stronger zone Isolated Hubs: Single hub = potential pivot point Stroke Analysis Stroke Length: Longer strokes = stronger momentum Stroke Speed: Fewer bars per stroke = explosive moves Stroke Clustering: Many short strokes = indecision Best Practices Parameter Optimization Adjust lookback period based on timeframe and volatility Lower periods (3-4): More strokes, more noise, faster signals Higher periods (7-10): Fewer strokes, cleaner structure, slower signals Confirmation Strategy Don't trade on strokes alone Combine with volume analysis Use candlestick patterns at hub boundaries Wait for breakout confirmation Risk Management Always place stops outside hub zones Use hub width to size positions (wider hub = smaller position) Exit if price re-enters broken hub from wrong direction Avoid Common Pitfalls Don't trade within central hubs (range-bound, unpredictable) Don't ignore higher timeframe hub structures Don't chase strokes after they've extended far from hub Don't trust single-stroke hubs (need 3+ strokes for validity) Performance Considerations Max Bars Limit: Set to 3600 to balance detail with performance Safe Distance Calculation: Only draws objects within 2000 bars of current price Object Cleanup: Automatically removes old drawing objects to prevent memory issues Efficient Arrays: Uses indexed arrays for fast lookup and processing Ideal Market Conditions Best Performance: Liquid markets with clear structure (major forex pairs, indices, large-cap stocks) Trending markets with periodic consolidations Medium to high volatility for clear stroke formation Less Effective: Extremely choppy, directionless markets Very low timeframes (< 5 minutes) with excessive noise Illiquid instruments with erratic price action Integration with Other Indicators Complementary Tools: Volume Profile: Confirm hub significance with volume nodes Moving Averages: Use for trend bias within stroke structure RSI/MACD: Momentum confirmation at hub boundaries Fibonacci Retracements: Hub levels often align with Fib levels Advantages ✓ Objective Structure: Removes subjectivity from market structure analysis ✓ Visual Clarity: Color-coded strokes and clear hub zones ✓ Multi-Timeframe Applicable: Works on all timeframes from minutes to months ✓ Complete Framework: Provides entry, exit, and risk management levels ✓ Theoretical Foundation: Based on proven Chan Theory methodology ✓ Customizable: Extensive parameter and visual customization options Limitations ⚠ Learning Curve: Requires understanding of Chan Theory principles ⚠ Lag Factor: Strokes confirm after price movements complete ⚠ Parameter Sensitivity: Different settings produce significantly different results ⚠ Choppy Market Struggles: Can generate excessive hubs in range-bound conditions ⚠ Computation Intensive: May slow down on lower-end systems with max bars setting Optimization Tips Timeframe Selection Scalping: 5-15 minute charts, lookback period 3-4 Day Trading: 15-60 minute charts, lookback period 4-5 Swing Trading: 4-hour to daily charts, lookback period 5-7 Position Trading: Daily to weekly charts, lookback period 7-10 Volatility Adjustment High volatility: Increase minimum gap bars to reduce noise Low volatility: Decrease lookback period to capture smaller moves Visual Optimization Use contrasting colors for different market conditions Adjust line widths based on chart resolution Toggle markers off for cleaner appearance once familiar with structure Quick Start Guide For Beginners: Start with default settings (5 lookback, 4 min gap) Enable "Show Info Table" to track stroke count Focus on identifying clear hub formations Practice waiting for price to break hub boundaries before trading For Advanced Users: Optimize lookback and gap parameters for your instrument Use hub strokes (yellow) to identify key consolidation zones Combine with multiple timeframes for confirmation Develop entry rules based on hub breakout/retest patterns This indicator provides a complete structural framework for understanding market behavior through the lens of Chan Theory, offering traders a systematic approach to identifying high-probability trading opportunities.
