Source: https://github.com/gbeced/pyalgotrade — clone it and read its README and examples before writing anything; its documented setup beats what you remember.
Stack: an event-driven Python library — feeds, a BacktestingStrategy subclass, and a broker abstraction that paper and live trading share.
Needs: Python 2.7/3.7, NumPy, SciPy, pytz, dateutil, requests; ws4py and tornado only if connecting to Bitstamp for paper/live Bitcoin trading.
Start: `pip install pyalgotrade`, then work through the tutorial's bar feed and BacktestingStrategy example before writing my own.
Limit: this project is deprecated and no longer maintained — the maintainer points to Basana as the successor.
Done means: you show me the backtest result for the tutorial strategy against sample data, and the strategy code you wrote.
Never place a live order. Paper or testnet until I say live in this chat.
Before you start, ask me: whether I still want PyAlgoTrade despite the deprecation notice or would rather start from Basana, and which data source I'm using.
