BIST100 Extractor

A simple, reproducible pipeline to download OHLCV time series for BIST 100 tickers from Yahoo Finance using a clean CLI with configurable --range and --interval.

Features

• CLI with argparse: set --range (e.g., 1mo, 6mo, 1y, 5y, max) and --interval (e.g., 1d, 1h, 5m).
• Saves per-ticker CSVs under data/.
• Solid repo hygiene (ruff + black), GitHub Actions CI, tests.
