Dataset
ProMarket Overview Snapshots
Daily market-wide index and advance/decline snapshots — per row: market code, as-of date, index level, index change, change %, advancers, decliners, and unchanged; sourced from the TWSE.
What this data is
Each row is one market's daily overview snapshot, carrying market_code / as_of_date / index_level / index_change / index_change_pct / advancers / decliners / unchanged (market code, as-of date, index level, index change, change %, advancers, decliners, and unchanged). Sourced from the TWSE, graded reference / master. The backend /v2/datasets meta exposes only grade / tier / point-in-time and no coverage window, so none is stated here.
Use cases
- Read breadth and sentiment quickly via advancers/decliners.
- Track daily index level and change context.
- Use as the top-level market overview for dashboards.
Why it matters for stock analysis
A market overview needs index plus advance/decline aggregated; this dataset serves it in one snapshot shape, no manual tallying.
