longbridge-harmonic

Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.

When to use

• When users inquire about harmonic patterns: "AAPL 有没有 Gartley 形态", "700.HK 蝙蝠形态分析", "TSLA PRZ 在哪里"
• Detect whether the XABCD structure meets the Fibonacci ratios of specific harmonic patterns
• Determine the position of the Potential Reversal Zone (PRZ) to assist entry decisions
• When users mention keywords such as "蝴蝶形态", "螃蟹形态", "XABCD"

Workflow

1. Extract the symbol code and standardize it to the

   <CODE>.<MARKET>

   format.
2. Obtain daily OHLCV data (200 candlesticks):
   bash

   longbridge kline <SYMBOL> --period day --count 200 --format json

3. Zigzag swing point identification (default threshold is 5%), take the latest 5 valid swing points as candidates for X-A-B-C-D.
4. Calculate Fibonacci ratios for each segment:

   • AB/XA

     : Retracement ratio of AB relative to XA

   • BC/AB

     : Retracement ratio of BC relative to AB

   • CD/BC

     : Extension ratio of CD relative to BC

   • AD/XA

     : Overall ratio of AD relative to XA (core of PRZ)
5. Compare with the tolerance ranges (±5%) of four standard harmonic patterns:

   Pattern	AB/XA	BC/AB	CD/BC	AD/XA
   Gartley	0.618	0.382–0.886	1.272–1.618	0.786
   Bat	0.382–0.500	0.382–0.886	1.618–2.618	0.886
   Butterfly	0.786	0.382–0.886	1.618–2.618	1.272–1.618
   Crab	0.382–0.618	0.382–0.886	2.618–3.618	1.618

6. If the match is successful, calculate the PRZ range (target range for point D), and determine the bullish (bullish XABCD) or bearish (bearish XABCD) direction.
7. Output the pattern name, PRZ range, direction, and stop-loss level.

If you are unsure about CLI parameters, run

longbridge kline --help

first to check the latest parameters.

CLI

# Daily candlestick data (primary data source)
longbridge kline AAPL.US --period day --count 200 --format json

# 4-hour candlestick data (auxiliary confirmation for short-term patterns, optional)
longbridge kline TSLA.US --period 60m --count 200 --format json

Output

• Identified pattern: e.g., "Bullish Gartley", "Bearish Bat"
• Price and date of each XABCD point
• PRZ range: [PRZ low, PRZ high] (potential landing range for point D)
• Trading direction: Bullish / Bearish
• Stop-loss level: The pattern becomes invalid if point X is breached
• Fibonacci ratio compliance (actual values vs standard values for each ratio)
