Dataset
ProPrice-Limit (daily)
Daily limit-up / limit-down and reference prices per stock — per row: trade date, ticker, market, limit-up price, limit-down price, and reference price; sourced from the TWSE.
What this data is
Each row is one stock's price limits for one day, carrying trade_date / ticker / market / limit_up_price / limit_down_price / reference_price (trade date, ticker, market, limit-up price, limit-down price, and reference price). Sourced from the TWSE, graded official, verified. The backend /v2/datasets meta exposes only grade / tier / point-in-time and no coverage window, so none is stated here.
Use cases
- Get each stock's daily limit-up/down bounds for tradability checks.
- Recover the change-percent base via reference price.
- Detect closes near the limit (a sentiment/liquidity signal).
Why it matters for stock analysis
Limit bounds move daily with the reference price; this dataset serves the official bounds and reference one row per day, no manual derivation.
