ReferenceSource: TWSE·Plan: free·Cost: 1 credits·GET /v2/datasets/broker-branch-reference

Broker-branch reference is a Taiwan market dataset sourced from TWSE, served by TW Market Data as GET /v2/datasets/broker-branch-reference.

Overview

`parent_broker_code`	string
`parent_broker_name`	string
`branch_code`	string	Broker branch code.
`branch_name`	string	Branch name.
`market`	string

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.
