Elliott Wave Analysis

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

Technical timing skill that positions a stock within its Elliott Wave cycle, confirms with momentum, and contextualizes with market environment. Three modules run sequentially; each result feeds the next.

When to Use

Do not trigger if: the user requests fundamental analysis, earnings preview, or valuation — use the relevant skill instead.

Data Sources

All price data comes from the Longbridge CLI. Before the first invocation of any longbridge subcommand in a session, run longbridge <subcommand> --help to confirm available flags, required arguments, and symbol format. Do this for every distinct subcommand you use (e.g. kline, quote, capital, news).

What to fetch

Symbol validation

Not all ticker-like strings are valid on Longbridge — index codes (e.g. SPX, HSI) are not tradable securities and will return invalid symbol. When you need broad-market data, use a tracking ETF instead (e.g. SPY.US for S&P 500, 2800.HK for HSI). If uncertain whether a symbol is supported, test with a small kline query first and handle the error gracefully.

Practical notes

• Always redirect CLI output to a temp file (e.g. /tmp/kline_day.json) — the CLI may append version notices to stdout that break JSON parsing.
• Use --format json on every call so output is machine-readable.
• Market environment data not available in CLI → use Web Search (see Module C).

Workflow

Step 1 — Pre-flight checks

Before analysis, verify:

1. Run longbridge kline --help and longbridge news --help if you haven't already in this session.
2. Fetch ≥ 300 daily candles for the target symbol in JSON format; save to a temp file.
3. Count returned bars. If < 250 bars → refuse analysis, reply:
   • CN: "历史数据不足250根日K，波浪计数不可靠，建议选择数据更充足的标的。"
   • EN: "Fewer than 250 daily candles available — wave count unreliable."
4. Fetch the 5 most recent news items for the symbol. If recent suspension/resumption or confirmed fraud/delisting → refuse.
5. For A-share: if ticker has "ST" prefix → refuse.

Step 2 — Module A: Wave Cycle Identification

Run scripts/signal_engine.py to compute swing points, wave count, and Fibonacci zones:

python3 scripts/signal_engine.py --kline /tmp/kline_day.json --symbol SYMBOL

The script outputs JSON with:

• stage: wave stage label (see Stage Labels below)
• count_a / count_b: two candidate count scenarios
• agreed: true if both counts give the same stage conclusion
• fib_zones: dict of Fibonacci price levels
• swings: list of recent swing points

If agreed is false → output "结构待确认 / Structure Unconfirmed", do not force a stage label.

Stage Labels (translate to user's language):

Step 3 — Module B: Momentum Confirmation

Compute from the same daily K-line data (all calculable from OHLCV, no extra API calls):

Critical divergence signals (must flag explicitly):

• Wave 5 top + MACD/RSI bearish divergence → high alert, potential reversal
• C-wave bottom + MACD/RSI bullish divergence → potential bottom
• Wave 3 + volume expansion → confirms wave 3 validity

Each indicator: state its current condition and whether it supports / is neutral toward / contradicts the Module A wave label. Do not sum into a single score.

Step 4 — Module C: Market Environment

Assess macro/market context relevant to the stock's market. Each signal is independent — do not aggregate into a score.

For CLI data in this module, run longbridge <subcommand> --help first if you haven't already. Index codes are not valid symbols on Longbridge — use tracking ETFs instead (see "Suggested proxy" column). If a proxy symbol returns an error, fall back to Web Search.

A-share (SSE/SZSE)

SGX

If a data item is unavailable from both CLI and Web Search, note "数据不可用 / Data unavailable" for that item only. Do not skip the whole module.

Step 5 — Generate Output

Assemble the three-module result into the output template below.

Output Template

The output uses four sections written in natural language — no bullet dumps. Match the user's language (Simplified CN / Traditional CN / English) throughout.

{2–3 paragraph prose narrative:}
- Para 1: Describe the swing sequence in plain language from the key bottom/origin,
  naming each wave and the price/date of each pivot. Explain why the current move
  matches the identified stage. Avoid jargon — translate wave numbers to meaning.

  State whether both agree ("两套视角结论一致") or conflict ("结构待确认，建议观望").
