pwb-alphaevolve 0.1.0

Autonomous evolution of algorithmic‑trading strategies using Backtrader, Papers With Backtest data, and OpenAI LLMs.

AlphaEvolve

Inspired by DeepMind’s AlphaEvolve coding agent—this project applies the same evolutionary-LLM principles to financial markets.

Autonomously discovers and back‑tests high‑performing algorithmic‑trading strategies using evolutionary LLM prompts, Backtrader, and the Papers‑With‑Backtest data ecosystem.

✨ Key Features

Layer	Highlights
Data	Zero‑setup loader for any Papers‑With‑Backtest dataset (pwb_toolbox) + caching to Feather
Strategies	Seed templates with EVOLVE‑BLOCK markers that the LLM mutates
Evaluator	Deterministic Backtrader walk‑forward, JSON KPIs (Sharpe, CAGR, Calmar, DD)
LLM Engine	OpenAI o3 structured‑output chat → JSON diff/patch system
Evolution	Async controller, SQLite hall‑of‑fame, optional MAP‑Elites niches
Dashboard	(optional) Streamlit live view of metrics & equity curves

🚀 Quickstart

# clone and install in editable mode
$ git clone https://github.com/paperswithbacktest/pwb-alphaevolve.git
$ cd pwb-alphaevolve
$ pip install -e .

# set your OpenAI key (model "o3" required)
$ export OPENAI_API_KEY=sk-...

# set your Papers‑With‑Backtest dataset (e.g. "paperswithbacktest/Stocks-Daily-Price")
$ export HF_ACCESS_TOKEN=hf_

# launch the evolution controller (infinite loop)
$ python scripts/run_controller.py
$ streamlit run scripts/dashboard.py

The dashboard uses Streamlit to visualize the evolution process and back‑test results.
