Requirements

⚠️ Extra dependency required

This skill depends on the third-party Python library czsc, which needs to be installed manually before use:

bash

pip install czsc

If installation is not possible in the environment, the LLM will fall back to manually implementing basic fractal logic (lower accuracy). This skill requires the czsc Python library. Install it before use:

pip install czsc

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

When to use

• User asks about Chan Theory-related analysis: "AAPL.US Chan Theory analysis", "Which buy point is 700.HK at now", "Help me check TSLA's Zhongshu"
• Identify fractals (top/bottom fractals), Bi (upward/downward Bi), Segment structures
• Determine the current type of buy/sell points (Buy 1/Buy 2/Buy 3/Sell 1/Sell 2/Sell 3)
• User mentions keywords like "Chan Zhong Shuo Chan", "Chan Master", "Chan Theory buy points"

Workflow

1. Extract the symbol code from user input and standardize it to

   <CODE>.<MARKET>

   format.
2. Obtain daily OHLCV data (300 K-lines):
   bash

   longbridge kline <SYMBOL> --period day --count 300 --format json

3. Convert JSON data to the

   RawBar

   list format required by czsc (fields:

   dt

   ,

   open

   ,

   high

   ,

   low

   ,

   close

   ,

   vol

   ).
4. Parse Chan Theory structures using the czsc library:
   python

   import czsc
   from czsc import CZSC
   # bars: list of czsc.RawBar
   c = CZSC(bars)
   # Fractals: c.fx_list
   # Bi: c.bi_list
   # Segments: c.seg_list (if available)
   # Zhongshu: c.zs_list (if available)

5. Read the latest Bi sequence and Zhongshu, match the buy/sell point logic:
   • Buy 1: A bottom fractal appears after a downward Bi touches the lower edge of Zhongshu
   • Buy 2: A bottom fractal appears after an upward Bi retraces without breaking the low of Zhongshu during Zhongshu oscillation
   • Buy 3: A bottom fractal appears after breaking the upper edge of Zhongshu and pulling back without breaking the high of Zhongshu
   • Sell point logic is symmetric (Sell 1/Sell 2/Sell 3)
6. Output analysis conclusions: current buy/sell point, latest Zhongshu range, latest fractal position.

If czsc is not installed in the environment, prompt the user to run

pip install czsc

first and then retry. If unsure about CLI parameters, run

longbridge kline --help

first to check the latest parameters.

CLI

# Obtain daily data (main data source)
longbridge kline AAPL.US --period day --count 300 --format json

# If shorter periods are needed for auxiliary judgment (optional)
longbridge kline 700.HK --period week --count 100 --format json

Output

• Current buy/sell point: Buy 1 / Buy 2 / Buy 3 / Sell 1 / Sell 2 / Sell 3 (or "No clear signal yet")
• Latest Zhongshu range: [Zhongshu low, Zhongshu high] (including prices)
• Latest fractal: Type (top/bottom) + price + date
• Latest Bi: Direction (upward/downward) + start/end prices
• Data source: Longbridge Securities / 数据来源：长桥证券 / 數據來源：長橋證券
