Akshare Online Alpha

Use this skill when the user wants Wyckoff-style analysis with online data fetch and source fallback.

Input Schema

Single/multi symbol analysis: - Inputs: stock code(s), optional CSV, optional chart image, text goals.

Portfolio decision analysis: - holdings (can be empty): [股票A+成本+数量, 股票B+成本+数量, ...] - cash: available cash amount - candidate (optional): stock code not currently in holdings - Optional CSV/image/text instructions are still supported.

Portfolio example: - holdings = [600519+1450+100, 000001+10.2+3000] - cash = 80000 - candidate = 300750

When To Use / Not Use

Use this skill when at least one condition is true: - User provides stock code(s) and asks for current/near-current analysis. - User provides holdings + cash + candidate and asks whether to switch positions. - User asks whether current holdings should be increased/reduced/kept. - User has no holdings and asks how to act with available cash. - User asks to combine CSV + online validation. - User provides chart image and asks for Wyckoff interpretation.

Do not use this skill when: - User only asks for generic Python/chart debugging unrelated to market analysis. - User requests purely offline historical analysis with no online data requirement.

Auto Intent Inference

When holdings/cash/candidate are provided, do not require the user to say "switch / add / reduce / empty-position".

Infer automatically from provided fields: - holdings non-empty + candidate provided: include rotation comparison and per-holding actions. - holdings non-empty + no candidate: provide per-holding add/reduce/hold/exit suggestions. - holdings empty + cash provided: provide empty-position cash deployment suggestion.

Required Execution Order

1. Validate input and parse structured fields:
2. Determine symbol-only flow or portfolio flow from input fields.
3. CSV (if provided): main source for historical structure.
4. Text instructions: constraints and goals.
5. Image (if provided): supplemental intraday/micro-structure signal.

6. In portfolio flow, parse holdings/cash/candidate(optional) before analysis.

7. Resolve current Beijing time before any trading suggestion:

8. Fetch actual current time from tool/system.
9. Convert to Asia/Shanghai.
10. Print 当前北京时间：YYYY-MM-DD HH:MM（UTC+8）.

11. Determine if in A-share continuous auction window.

12. Enforce trading-session rules:

13. If not in tradable session, only provide post-market review/next-day plan/order strategy.

14. Do not output immediate intraday execution commands.

15. Fetch data with online source switching:

16. Use rules/source-fallbacks.md order.
17. For each symbol, keep source audit log.
18. If source fails, schema check fails, or rows are insufficient, switch source.

19. In portfolio flow, fetch all holding symbols and candidate symbol when provided.

20. Perform Wyckoff analysis first:

21. Analyze latest 500 days structure with MA50/MA200.
22. Identify phases/events without forcing full phase set.

23. Allow event-date news checks only for verification, not as decision basis.

24. In portfolio flow, produce a Wyckoff-style portfolio recommendation:

25. For each holding, give one action: add / reduce / hold / exit.
26. If candidate is provided, compare candidate vs current holdings from structure strength, phase position, and event quality.
27. If candidate is provided, identify which current holding is structurally weakest and whether rotation is needed.
28. If holdings are empty, provide an empty-position suggestion using available cash and current structure context.
29. Use cost/qty/cash to give concrete action suggestions in narrative form.

30. Keep final recommendation in Wyckoff tone and clearly state action labels such as switch / partial switch / hold / add / reduce.

31. Plot only when allowed:

32. If current time is intraday trading time, skip plotting.
33. Otherwise generate plotting code/result using hard rendering constraints from system prompt.

Fixed Output Contract

Always output in this order: 1. 当前北京时间：YYYY-MM-DD HH:MM（UTC+8） 2. Trading verdict: - 当前是否可盘中交易：是/否 - If no: 当前不可盘中交易（原因：...） 3. Data audit table per symbol: - symbol - source_used - rows_kept - window_end_date - fallback_count 4. Wyckoff analysis result: - Current cycle background and phase (only what is evidenced). - Key events (SC/ST/Spring/LPS/SOS/UTAD if present) with concise rationale. - Action boundaries respecting T+1 and current session status. 5. Portfolio action section (portfolio flow only): - Holdings snapshot from provided cost/qty/cash. - Per-holding action suggestions (add / reduce / hold / exit) with reasoning. - Candidate vs weakest holding comparison (if candidate is provided). - Empty-position cash action suggestion (if holdings are empty). - Final action summary in Wyckoff tone. 6. Plotting section (only when allowed by session rules): - Python code and/or generated chart result with Chinese annotation constraints.

Failure And Degrade Rules

• If all data sources fail for a symbol, report that symbol as data_unavailable and continue with remaining symbols.
• If fewer than 30 valid rows are available, do not force phase labeling; return "insufficient structure depth".
• If image is unreadable, explicitly state parse failure reason and continue with text/CSV path.
• Never invent OHLCV rows, event timestamps, or trading-day status.

Hard Constraints

• Do not change the fixed prompt wording unless explicitly requested.
• Do not fabricate missing OHLCV rows.
• Do not ignore image input if image is parseable.
• Do not use opaque white text boxes in chart annotations.
• If fetching data requires running Python scripts, run them only in a sandboxed environment.
• Prefer direct web/API fetch first; use Python scripts only when needed for fallback, parsing, or normalization.
