🇹🇼 Taiwan MOPS Company Announcements — Material Disclosures

Real-time Taiwan TWSE/MOPS corporate disclosures from the keyless TWSE OpenAPI gateway. Taiwan's Market Observation Post System (公開資訊觀測站, MOPS) is the statutory disclosure portal where every TWSE-listed issuer publishes material announcements (重大訊息), 5%+ shareholder filings (大股東持股), director-and-officer holdings (董監事持股), monthly revenue (月營收), and IPO pipeline updates within minutes of board approval — mandated under the TW Securities and Exchange Act §36-1.

This actor pulls the MOPS data through the regulatory-blessed TWSE OpenAPI at openapi.twse.com.tw/v1/ — a keyless JSON gateway that mirrors the MOPS portal's same-day disclosure feed without the consumer-portal referer wall. Output is structured JSON with 4-digit Taiwanese securities codes, Traditional-Chinese company names, classified disclosure types, and the canonical source URL per row. Built for Taiwan-focused event-driven funds, semi-supply-chain analysts tracking TSMC/UMC suppliers, corporate-governance researchers, and individual investors monitoring 公開收購 (tender offers) and 股東會 (AGM) announcements.

⚖️ Legal & data source notes

• Data source: TWSE OpenAPI gateway — the Taiwan Stock Exchange's keyless JSON conduit for MOPS (公開資訊觀測站) disclosures. Endpoints used: t187ap04_L (material announcements), t187ap08_L (5%+ shareholder filings), t187ap03_L (director / officer holdings), t187ap05_L (monthly revenue), and company/newlisting (IPO pipeline).
• Statutory basis: TW Securities and Exchange Act §36-1 mandates same-day material-information disclosure (重大訊息揭露) for TWSE-listed issuers. Officer / 5%-shareholder disclosure is mandated under SEA §22-2 (insider reporting) and §43-1 (5%-shareholder). MOPS / TWSE OpenAPI is the regulatory-blessed conduit — Taiwan's analogue to Japan's TDnet and Korea's DART.
• License: TWSE OpenAPI is published under Taiwan's Open Government Data License v1 (CC BY 4.0 equivalent). No commercial restriction. No PII — issuer-level corporate announcements only.
• MOPS portal note: the MOPS consumer portal (mops.twse.com.tw/mops/web/ajax_*) is referer-walled with a security-check banner (「因為安全性考量」). This actor uses the OpenAPI route — the same upstream data, keyless and stable. The mops_portal_url field is a reference cross-link for analysts who want to view the disclosure in the official UI.
• Polite-bot identification: every request carries User-Agent: NexGenDataBot/1.0 (+https://thenextgennexus.com/bot; contact: hello@thenextgennexus.com) and paces ≥1.5s between buckets to stay well within TWSE's stated open-data norms.
• Snapshot semantics: TWSE OpenAPI endpoints serve the current rolling snapshot — t187ap04_L and t187ap05_L carry recent material announcements / monthly revenue; t187ap03_L and t187ap08_L are reference snapshots updated on regulatory cadence; company/newlisting is the live IPO pipeline. The date_from / date_to window filters within whatever the upstream snapshot delivers.

❓ FAQ

Q: How is this different from the twse-stock-screener actor? A: twse-stock-screener covers TWSE + TPEx mainboard quotes (price, volume, market cap). This actor covers MOPS disclosure events — material announcements, governance reports, IPO pipeline, monthly revenue. The two are complementary — use the screener to build a watchlist, then this actor to follow that watchlist's disclosure feed.

Q: Why is disclosure_title in Traditional Chinese? A: TWSE / MOPS publish all titles in Traditional Chinese (zh-Hant-TW) only — this is the official text under the SEA §36-1 disclosure mandate. English translation is opt-in; pipe disclosure_title through DeepL or Google Cloud Translation for downstream consumers. Note: Taiwan uses Traditional Chinese (繁體中文) — distinct from the Simplified Chinese (zh-CN) used in mainland China disclosure feeds.

Q: Why are some ROC dates 7 digits and others 6? A: Taiwan's 民國 (ROC) calendar starts at year 1912 = ROC 1. Year-100+ dates are 7 digits (1150601 = ROC 115 = 2026, June 1); pre-2011 dates are 6 digits (990601 = ROC 99 = 2010). The actor handles both forms transparently and emits ISO YYYY-MM-DD in disclosure_date.

Q: Why does tender_offers map to t187ap08_L (5%+ shareholders) and not to a dedicated tender-offer endpoint? A: Taiwan tender-offer (公開收購 / TOB) disclosures flow through the MOPS material-announcement feed (t187ap04_L) tagged with the tender-offer compliance clause, not a separate endpoint. The 5%+ shareholder filings (t187ap08_L) are the closest TWSE OpenAPI proxy for activist / pre-TOB signal — large positions that often precede or accompany tender-offer activity. For pure tender-offer events, use disclosure_type=material_announcements and filter the title for 公開收購 or compliance clauses 第14款 / 第15款.

Q: Why are weekends + Taiwan holidays returning zero rows in the material-announcements bucket? A: TWSE / MOPS only operate on trading days. The material-announcements feed naturally returns zero rows for non-trading dates — the actor exits cleanly with 0 results (no error, no crash, no charge beyond apify-actor-start). Snapshot buckets (officer holdings, IPO pipeline) are unaffected.
