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:

• Determine symbol-only flow or portfolio flow from input fields.
• CSV (if provided): main source for historical structure.
• Text instructions: constraints and goals.
• Image (if provided): supplemental intraday/micro-structure signal.
• In portfolio flow, parse holdings/cash/candidate(optional) before analysis.

2. Resolve current Beijing time before any trading suggestion:

• Fetch actual current time from tool/system.
• Convert to Asia/Shanghai.
• Print 当前北京时间：YYYY-MM-DD HH:MM（UTC+8）.
• Determine if in A-share continuous auction window.

3. Enforce trading-session rules:

• If not in tradable session, only provide post-market review/next-day plan/order strategy.
• Do not output immediate intraday execution commands.

4. Fetch data with online source switching:

• Use rules/source-fallbacks.md order.
• For each symbol, keep source audit log.
• If source fails, schema check fails, or rows are insufficient, switch source.
• In portfolio flow, fetch all holding symbols and candidate symbol when provided.

5. Perform Wyckoff analysis first:

• Analyze latest 500 days structure with MA50/MA200.
• Identify phases/events without forcing full phase set.
• Allow event-date news checks only for verification, not as decision basis.

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

• For each holding, give one action: add / reduce / hold / exit.
• If candidate is provided, compare candidate vs current holdings from structure strength, phase position, and event quality.
• If candidate is provided, identify which current holding is structurally weakest and whether rotation is needed.
• If holdings are empty, provide an empty-position suggestion using available cash and current structure context.
• Use cost/qty/cash to give concrete action suggestions in narrative form.
• Keep final recommendation in Wyckoff tone and clearly state action labels such as switch / partial switch / hold / add / reduce.

7. Plot only when allowed:

• If current time is intraday trading time, skip plotting.
• 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.
