Market Structure & Reference

Warrants reference

Warrants reference — the master record for each listed warrant (identity, underlying, type and key contract terms).

← Warrants reference overview

ReferenceSource: TWSE / TPEx·Plan: free·Cost: 1 credits·GET /v2/datasets/warrants-reference

Warrants reference is a Taiwan market dataset sourced from TWSE / TPEx, served by TW Market Data as GET /v2/datasets/warrants-reference.

Overview

warrants-reference is a reference dataset: one active record per listed warrant, used to resolve a warrant code to its underlying, type and contract terms. It is an active snapshot of currently listed warrants, not a price or trading time series.

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.
