Dataset
A TWSE-only securities lending dataset providing lending balance, borrows, returns, close price, and data-gap signals.
Download without registration: sample data using one of the five no-key symbols (2330 TSMC) as the example.
This dataset organizes TWSE official TWT72U daily lending data, retaining lending balance, borrows, returns, market value, source lineage, and data_gaps — suited to observing borrow-source supply and lending pressure.
Securities lending data adds borrow-source supply information beyond price, institutional, and margin data, helping observe short-selling pressure, trading crowdedness, and market structure.
Publicly verified coverage is currently 2020-01-02..2026-06-04, totaling 1,629,223 rows across 1,292 TWSE symbols; no claim of TPEx or full-market coverage.
Update cadence and available dates depend on official-source supply; known source gaps are preserved in the response and copy, and are not filled with estimated values.
Follows official-first and explicit lineage/data_gaps principles; claims TWSE-only, preserves known source gaps, and does not expose the raw/full body.
