README

BackTest_MCP

股票回测引擎 MCP 服务器(QuantForge MCP)。

参考说明

本项目核心回测引擎代码参考自开源仓库 theNeuralHorizon/quantforge。 在此基础上,结合 MCP 场景补充了工具化封装、服务层与运行流程。

功能概览

  • 提供股票数据拉取/缓存能力(默认 yfinance)。
  • 提供动态策略代码校验与回测执行。
  • 提供回测结果查询、工件下载、Markdown 报告生成。
  • 暴露策略生成辅助目录(指标/风控/组合函数与策略样例)。

环境要求

  • Python 3.10+
  • 可选:Docker(用于沙箱执行回测 worker)

安装

python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
pip install -r requirements.txt

启动服务

方式 1:stdio(默认,推荐给 MCP Client)

python -m quantforge_mcp

方式 2:SSE

set QUANTFORGE_TRANSPORT=sse   # Linux/macOS 用 export
set QUANTFORGE_SSE_PORT=8001
python -m quantforge_mcp

MCP 工具列表

Catalog

  • list_compute_modules:列出可用于策略生成的计算模块导出函数(含签名/描述)。
  • list_strategy_examples:列出内置策略样例文件与类说明。

Data

  • get_stock_data(symbol, start, end, interval):获取并汇总 OHLCV 数据。
  • list_cached_symbols():查看本地缓存股票代码。
  • prefetch_stock_data(symbols, start, end, interval):批量预拉取数据。

Backtest

  • validate_strategy_code(code):策略代码 AST 安全校验。
  • validate_backtest_config(config_json):回测配置校验。
  • run_backtest_dynamic(code, config_json):运行动态策略回测。
  • get_backtest_result(job_id):查询回测结果。
  • generate_backtest_report(job_id, title):生成 Markdown 报告。
  • get_backtest_artifacts(job_id, kind):获取回测工件。

MCP 资源列表

  • quantforge://codegen/spec:策略代码生成规范。
  • quantforge://data/symbol-guide:symbol 使用指南。
  • quantforge://examples/nvda_dynamic_config:动态回测配置示例。

关键环境变量

所有配置项以 QUANTFORGE_ 为前缀:

  • QUANTFORGE_DB_PATH(默认 quantforge_mcp/storage/quantforge.db
  • QUANTFORGE_ARTIFACTS_DIR(默认 quantforge_mcp/storage/artifacts
  • QUANTFORGE_DATA_SOURCE(默认 yfinance
  • QUANTFORGE_ALLOW_SYNTHETIC_FALLBACK(默认 true
  • QUANTFORGE_DOCKER_ENABLED(默认 true
  • QUANTFORGE_DOCKER_IMAGE(默认 quantforge-worker:latest
  • QUANTFORGE_SANDBOX_TIMEOUT_SEC(默认 120
  • QUANTFORGE_SANDBOX_MEM_LIMIT(默认 512m
  • QUANTFORGE_SANDBOX_CPU_QUOTA(默认 100000
  • QUANTFORGE_TRANSPORTstdio / sse,默认 stdio
  • QUANTFORGE_SSE_PORT(默认 8001

关于 quantforge_stock/ml

quantforge_stock/ml 目前处于开发中,默认禁用。

  • 默认导入会抛出 ImportError,防止被其他模块误调用。
  • 若你明确需要启用实验能力,请手动设置:
set QUANTFORGE_ENABLE_EXPERIMENTAL_ML=1   # Linux/macOS 用 export

常见问题

  • ModuleNotFoundError: quantforge_mcp
    需在 quantforge_mcp 目录的上一级执行,或保证该目录名为 quantforge_mcp 并在 PYTHONPATH 中。

  • 首次回测较慢
    首次拉取行情与初始化数据库会有冷启动开销,属于正常现象。
