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
| Trigger | Example |
|---|
| Wave position inquiry | "TSLA.US 现在是第几浪" / "700.HK波浪分析" |
| Technical timing | "NVDA.US 技术择时" / "苹果波浪择时" |
| Pre-trade check | "我想买，波浪角度看合适吗" |
| General wave theory | "帮我做个艾略特波浪分析" |
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
subcommand in a session, run longbridge <subcommand> --help
Do this for every distinct
subcommand you use (e.g.
,
,
,
).
What to fetch
| Data | Purpose | Minimum |
|---|
| Daily K-line | Primary wave analysis | ≥ 250 bars, JSON |
| Weekly K-line | Higher-degree wave context | ~100 bars, JSON |
| Current quote | Latest price, range | JSON |
| Capital flow | Southbound / Northbound flow (if available) | JSON |
Symbol validation
Not all ticker-like strings are valid on Longbridge —
index codes (e.g. SPX, HSI) are
not tradable securities and will return . 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. ) — the CLI may
append version notices to stdout that break JSON parsing.
- Use 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:
- Run and if you haven't already in this session.
- Fetch ≥ 300 daily candles for the target symbol in JSON format; save to a temp file.
- 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."
- Fetch the 5 most recent news items for the symbol. If recent suspension/resumption or confirmed fraud/delisting → refuse.
- For A-share: if ticker has "ST" prefix → refuse.
Step 2 — Module A: Wave Cycle Identification
Run
to compute swing points, wave count, and Fibonacci zones:
bash
python3 scripts/signal_engine.py --kline /tmp/kline_day.json --symbol SYMBOL
The script outputs JSON with:
- : wave stage label (see Stage Labels below)
- / : two candidate count scenarios
- : true if both counts give the same stage conclusion
- : dict of Fibonacci price levels
- : list of recent swing points
If is false → output "结构待确认 / Structure Unconfirmed", do not force a stage label.
Stage Labels (translate to user's language):
| Internal | Simplified CN | Traditional CN | English |
|---|
| 上升初段 | 上升初段 | Early Impulse |
| 主升段（③浪） | 主升段（③浪） | Wave 3 Advance |
| 上升末段（⑤浪） | 上升末段（⑤浪） | Late Impulse (Wave 5) |
| 顶部区域 | 頂部區域 | Top Zone |
| 调整段（ABC） | 調整段（ABC） | ABC Correction |
| 底部区域 | 底部區域 | Bottom Zone |
| 结构待确认 | 結構待確認 | Structure Unconfirmed |
Step 3 — Module B: Momentum Confirmation
Compute from the same daily K-line data (all calculable from OHLCV, no extra API calls):
| Indicator | Parameters | Signal to Report |
|---|
| MACD | 12/26/9 EMA | Line vs signal, histogram direction, divergence vs price |
| RSI | 14-period | Level (>70 overbought / <30 oversold), divergence vs price |
| Volume | Raw volume | Wave 3 highest volume? Wave 5 / C-wave volume vs prior wave |
| MA trend | 20 / 50 SMA | Price above/below each MA; MA slope direction |
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.
HK (HKEX)
| Signal | How to get | Suggested proxy | Web Search fallback |
|---|
| HSI trend (60-day) | — 60 daily bars | 2800.HK (Tracker Fund) | "恒生指数 今日" |
| Southbound flow | for the target symbol | — | "南向资金 今日净买入" |
| Short-sell ratio | Not in CLI | — | "[stock name] HK short selling ratio" |
| Recent policy / regulatory | — | — | Web Search |
US (NYSE/NASDAQ)
| Signal | How to get | Suggested proxy | Web Search fallback |
|---|
| S&P 500 trend (60-day) | — 60 daily bars | SPY.US | "S&P 500 price today" |
| VIX level | Not in CLI | — | "VIX current level" |
| Put/call ratio | Not in CLI | — | "CBOE equity put call ratio" |
| Sector ETF trend | — 30 daily bars | Relevant sector ETF (e.g. XLK.US, XLE.US) | Web Search |
A-share (SSE/SZSE)
| Signal | How to get | Suggested proxy | Web Search fallback |
|---|
| Shanghai Composite trend | — 60 daily bars | 000001.SH | "上证指数 今日" |
| Northbound flow | for the target symbol | — | "北向资金 今日" |
| Margin balance trend | Not in CLI | — | "融资余额" |
| Recent CSRC/policy signals | — | — | Web Search |
SGX
| Signal | How to get | Web Search fallback |
|---|
| STI trend | CLI coverage may be limited — try a proxy first, expect errors | "Straits Times Index today" |
| Stock-specific news | for the target symbol | "[company] SGX news" |
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.
【{Company Name}（{SYMBOL}）】波浪技术分析
分析日期：{today} ｜ 当前价：{price} ｜ 今日区间：{low} – {high}
【一】波浪结构
当前阶段
{stage_label_natural} · {one-line characterisation}
{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.
- Para 2: Confirm with a second counting perspective (different threshold / degree).
State whether both agree ("两套视角结论一致") or conflict ("结构待确认，建议观望").
- Para 3 (if unconfirmed): Explain what would resolve the ambiguity.

【四】做这个分析前，有几点需要告诉你
{3–4 short paragraphs of plain-language caveats tailored to THIS stock's specific situation:}
- Subjectivity of wave counting and what gives/reduces confidence here

- Any unusual price characteristics (e.g. Fibonacci targets already breached, extreme RSI)
- Reminder that daily close matters more than intraday wicks for invalidation levels

Output rules
- No bullet-list dumps in sections 【一】–【三】. Use tables for data, prose for narrative.
- ASCII wave diagram: include when ; omit when .
- Section 【四】is mandatory — always write stock-specific caveats, never generic boilerplate.
- If : replace 【一】prose with "两套计数方案结论不一致，建议观望" and skip the diagram and Fibonacci tables.
- Disclaimer is system-injected at the end; never omit or modify it.
