APAC Disclosure Monitor — New Market Announcement Alerts

Monitor official APAC market announcements and receive delta alerts for new company disclosures across supported exchanges. This is not a bundle of raw scrapers — it watches issuers, companies, exchanges, or keywords, snapshots what it has seen, and emits only new announcements since the previous run.

What it does

On each run it pulls recent disclosures from each selected exchange's official feed (via NexGenData's owned per-exchange disclosure Actors), normalizes them to a single schema, records what it has seen, and in delta mode emits only new announcements. Schedule it daily and you only ever see new disclosures. One exchange being temporarily unavailable never fails the whole run — the others still return, with a clear partial-results warning.

Live coverage (v1)

• ASX — Australian Securities Exchange company announcements
• HKEX — Hong Kong Exchanges news/disclosures
• TWSE — Taiwan MOPS market disclosures
• KRX — Korea KIND disclosures
• NSE / India — India SEBI filings

SGX (Singapore Exchange) is supported but intermittent — its underlying feed uses live browser interception that occasionally returns nothing, so it is not in the default set and not claimed as reliable coverage. Include SGX explicitly to try it.

Other APAC markets (e.g. Japan TDnet, Philippines PSE) are planned and not included in this version.

Who it's for

Funds and analysts with APAC coverage, investor relations, compliance, and corporate-development teams that need one recurring watch across multiple Asian markets.

Recommended setup

Run once in full mode to baseline, then schedule daily delta runs. The first delta run per exchange records a baseline and emits nothing (expected); after that you get only new announcements.

Inputs

exchanges, tickers, company_names, keywords, categories, lookback_days (default 3), mode (delta/full), max_announcements (per exchange), include_raw.

Outputs

exchange, ticker, company, announcement_title, announcement_type, category, published_at, announcement_date, document_url, source_url, change_type, matched_watch, detected_at (plus raw when enabled).

Delta mode vs full mode

• full — emits every matching announcement in the window per exchange and refreshes the snapshot.
• delta — emits only announcements whose source ID (or exchange + ticker/company + title + date fallback) has not been seen before. First delta run baselines and emits nothing; later runs emit only new disclosures.

Limitations

This is an alerting tool, not investment or legal advice. It monitors recent disclosures on a rolling window via the owned per-exchange source Actors; coverage and timing follow each exchange's official feed. Some markets provide a company name but no ticker (e.g. India SEBI). Always confirm against the official exchange filing before acting.
