Market & Prices

Price-limit (daily)

Daily price limits — the official upper and lower limit prices and the reference price for each stock per trading day.

← Price-limit (daily) overview

VerifiedSource: TWSE·Plan: max·Cost: 2 credits·GET /v2/datasets/stock-price-limit-daily

Price-limit (daily) is a Taiwan market dataset sourced from TWSE, served by TW Market Data as GET /v2/datasets/stock-price-limit-daily.

Overview

stock-price-limit-daily returns one row per stock per trading day with the official upper and lower price limits and the reference price they are computed from. Each row carries its source role, so the limits trace back to the exchange publication rather than being re-derived on the client.

FieldTypeDescription
trade_datestring
tickerstring
marketstring
limit_up_pricenumber
limit_down_pricenumber
reference_pricenumberReference price the limits are set from.

Chinese data values are shown as a marker here so this page stays in English; the /zh page shows them verbatim.

Provenance

These columns are returned alongside the data and record where the row came from. They are provenance, not the dataset's subject matter, so they are listed here rather than in the field table.
