# FinLab Quant Research Platform

> FinLab, founded in 2018 by Cheng-Yu Han (韓承佑), helps investors research U.S. and Taiwan markets with market data, a Python SDK, a backtesting engine, strategy reports, and AI research tools. Site: https://finlab.finance.

FinLab ships an open Python package: `pip install finlab`. Data authenticity statement: every performance number published on this site (CAGR, Sharpe ratio, max drawdown) comes from a real `finlab` backtest on Taiwan-stock data, with the backtest window stated in the article and the strategy code (`strategy.py`) downloadable from the page itself. Numbers are dated, reproducible measurements, never illustrative placeholders. The site is organized around three pillar topics: 量化交易 (quantitative trading), 程式交易 (program trading), and 股票選股 (stock selection); see the Pillar guides section below.
