Disposition securities period

Disposition securities period (preview) — securities placed under disposition measures by the exchange, with the period and the trading restriction applied.

ReferenceSource: TWSE·Plan: pro·Cost: 2 credits·GET /v2/datasets/disposition-securities-period

Overview

disposition-securities-period returns one row per disposition placed on a security, with the start and end of the disposition period and the measure applied (for example matched-auction throttling), sourced from the official TWSE announcements. This is a private-beta preview with partial coverage. Each row carries its source role and lineage back to the upstream disclosure.

FieldTypeDescription
symbolstringTicker.
period_startstringStart of the disposition period.
period_endstringEnd of the disposition period.
measurestringTrading restriction applied during the period.
source_rolestringCanonical source role (official_twse_disposition).
lineageobjectUpstream authority + release for the disposition.

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

Getting started

  1. Put your key in the X-API-Key header.
  2. Add query parameters (symbol, date range, limit).
  3. Send the request and read the data array.
curl "https://api.twmarketdata.com/v2/datasets/disposition-securities-period?symbol=2330" \  -H "X-API-Key: sk_live_..."

Filtering

ParameterRequiredTypeDescription
symbolYesstringTicker, e.g. 2330.
start_dateNostring (YYYY-MM-DD)Start of the query range.
end_dateNostring (YYYY-MM-DD)End of the query range.
limitNointegerMaximum rows to return.

Python

A first call:

import requests resp = requests.get(    "https://api.twmarketdata.com/v2/datasets/disposition-securities-period",    params={"symbol": "2330"},    headers={"X-API-Key": "sk_live_..."},)resp.raise_for_status()print(resp.json()["data"])

With a date-range filter:

import requests # The full verified example — the same call with every supported filter set.resp = requests.get(    "https://api.twmarketdata.com/v2/datasets/disposition-securities-period",    params={"symbol": "2330"},    headers={"X-API-Key": "sk_live_..."},)resp.raise_for_status()for row in resp.json()["data"]:    print(row)

OpenAPI

This endpoint is GET /v2/datasets/disposition-securities-period. The full machine-readable schema (parameters, security, response envelope) lives in the OpenAPI spec.

Notes & limitations

  • Private-beta preview: coverage is partial and the schema may change before general availability — the absence of a disposition means "not captured", not "never disposed".
  • A disposition period restricts how a security trades: apply the period bounds when reconstructing intraday execution assumptions for a past date.

Request & Response

Request

curl "https://api.twmarketdata.com/v2/datasets/disposition-securities-period?symbol=2330&start_date=2026-01-01&end_date=2026-06-30&limit=5" \  -H "X-API-Key: $TWMD_API_KEY"

This dataset returns its rows under "data". The envelope differs between datasets, so read this one rather than reusing another page's shape.
