## 能查什麼

- 台股上市股票與 ETF 的盤中即時報價
- 前一交易日的開盤、最高、最低、收盤與成交量
- 單一 ETF 的基本資料、追蹤指數與定期定額熱度
- 臺灣期貨交易所的每日行情、三大法人與大額交易人未沖銷部位
- 臺灣證交所與期交所合計 275 個公開資料集的搜尋與查詢

## Limits / 查不到什麼

- Over-the-counter (TPEx) stocks have intraday quotes only; historical and statistical reports are unavailable because the Taipei Exchange open-data host refuses cloud-originated connections.
- 上櫃（OTC）股票只有盤中即時報價；歷史與統計報表取不到，因為證券櫃檯買賣中心的開放資料主機會拒絕來自雲端的連線。
- Taiwan Stock MCP does not provide technical indicators, stock screening or investment advice, and computes no forecasts of its own.
- 台股 MCP 不提供技術指標、選股或投資建議，也不做任何自行計算的預測。

## Freshness / 資料新鮮度

- Intraday quotes refresh roughly every 5 seconds, sourced from the exchange's market-information site, best-effort.
- Every other report is current to the previous trading day and cached at the edge for one hour.
- 盤中即時報價約每 5 秒更新，來源是證交所基本市況報導站，屬盡力而為；其餘報表最新到前一交易日，並在邊緣快取一小時。
