Dataset
StarterPrice Move Context Cards
The context around a stock's large-move day — per row: stock change, market change, relative-to-market, magnitude bucket, hit track, limit-move flag/method, and related events; sourced from the TWSE.
What this data is
Each row is one stock's context for one large-move day, carrying pct_change / market_pct_change / relative_to_market / magnitude_bucket / hit_track / limit_move_flag / limit_move_flag_method / events (stock change, market change, relative-to-market, magnitude bucket, hit track, limit-move flag/method, and related events). Sourced from the TWSE, graded derived (computed from official data). Keyed on the data as-of date and point-in-time safe; The backend /v2/datasets meta exposes only grade / tier / point-in-time and no coverage window, so none is stated here.
Use cases
- Separate idiosyncratic from systematic moves via relative-to-market.
- Screen large-move events fast via the magnitude bucket.
- Explain moves by joining related events.
Why it matters for stock analysis
Raw change percent can't explain a move; this dataset adds relative-to-market, magnitude buckets, and related events as context, point-in-time safe.
Coverage / Freshness / Source Policy
The context around a stock's large-move day; one row per stock's context for large-move day, fields pct_change / market_pct_change / relative_to_market / magnitude_bucket / hit_track / limit_move_flag; sourced from the TWSE (graded derived (computed from official data)). Keyed on the data as-of date and point-in-time safe; (The backend /v2/datasets meta provides no coverage window, so none is stated.)
Updated as the backend refreshes; cadence follows the source's release schedule.
Sourced from the TWSE (graded derived (computed from official data)); not investment advice.
