Wind MATLAB Data and Trading Interface Version 1.3 User Manual

About this manual

This manual introduces the Wind MATLAB Data and Trading Interface, a set of functions that allow MATLAB users to retrieve financial market data, historical series, minute‑level data, real‑time quotes, data sets, screening, asset‑management reports and trading operations. It explains how to install, register, and launch the interface, and provides a menu‑driven wizard for generating command lines.

The document includes detailed descriptions of each function (e.g., wsd, wss, wsi, wsq, wset, wpf, tdays), usage examples for equities, bonds, futures, and portfolio analysis, as well as a FAQ section that addresses common installation issues, data‑limit errors, and unsupported features such as sector constituent data. This manual is written in Chinese.
