TW Market Data turns official data from TWSE, TPEx, MOPS, and TAIFEX into a consistent, easy-to-integrate REST API. We ingest and parse every dataset directly from the official sources — never second-hand.
Every response carries its source and knowledge_date; gaps are marked honestly, and holes are never filled with estimates.
Daily prices for individual TWSE-listed stocks go back to 2004, and we keep the full price history of 311 stocks that have stopped trading (delisted / long-term suspended), so backtests aren't inflated by survivorship bias. Currently available:
- TWSE daily prices — Daily OHLCV for individual TWSE-listed stocks, including stocks that have stopped trading, from 2004.
- Monthly revenue — Monthly revenue with YoY/MoM, from 2010 — the monthly-frequency fundamentals unique to Taiwan equities.
- Financial statements — Income statement, balance sheet, and cash flow statement.
- Institutional investors — Daily net buy/sell by foreign investors, investment trusts, and dealers, per stock. US 13F filings lag 45 days; here it is daily.
- Valuation metrics — P/E, P/B, and dividend yield, daily.
- Technical indicators — Common technical indicators, daily.
- Margin trading & short selling — Daily margin and short balances.
- Material announcements — Material information and announcements from TWSE- and TPEx-listed companies.
TPEx daily bars and adjusted prices are currently in beta, with coverage marked per dataset.
- Structured JSON — Consistent field naming — every endpoint integrates the same way.
- Standardized — Accounting line items map to one taxonomy, so different companies and periods compare directly.
- Original values preserved — The company's originally reported figures and labels are also provided, with no speculative adjustments.
- Traceable — Every record carries its source and knowledge_date, supporting point-in-time replay.
- AI financial agents and LLM pipelines that need data to feed on
- Quantitative research and factor development
- Backtesting and automated trading systems
- The internal data layer of fintech products
- Official first-party sources only — Wired directly to TWSE/TPEx/MOPS/TAIFEX, with no second-hand intermediaries.
- Transparent coverage — Every dataset clearly states its coverage period, source, and limits — no pretending everything is available.
- No look-ahead — knowledge_date is preserved, so backtests see only the data known at the time.
- Built for machines — Optimized for programmatic calls, not for human web browsing.
