High-performance quantitative trading framework based on Rust and Python
Project description
AKQuant 是一款专为量化投研设计的下一代高性能混合框架。核心引擎采用 Rust 编写以确保极致的执行效率,同时提供优雅的 Python 接口以维持灵活的策略开发体验。
🚀 核心亮点:
- 极致性能:得益于 Rust 的零开销抽象与 Zero-Copy 数据架构,回测速度较传统纯 Python 框架(如 Backtrader)提升 X倍+。
- 原生 ML 支持:内置 Walk-forward Validation(滚动训练)框架,无缝集成 PyTorch/Scikit-learn,让 AI 策略开发从实验到回测一气呵成。
- 因子表达式引擎:内置 Polars 驱动的高性能因子计算引擎,支持
Rank(Ts_Mean(Close, 5))等 Alpha101 风格公式,自动处理并行计算与数据对齐。 - 参数优化:内置多进程网格搜索(Grid Search)框架,支持策略参数的高效并行优化。
- 专业级风控:内置完善的订单流管理与即时风控模块,支持多资产组合回测。

安装说明
AKQuant 已发布至 PyPI,无需安装 Rust 环境即可直接使用。
pip install akquant
快速开始
以下是一个简单的策略示例:
import akquant as aq
import akshare as ak
from akquant import Strategy
# 1. 准备数据
# 使用 akshare 获取 A 股历史数据 (需安装: pip install akshare)
df = ak.stock_zh_a_daily(symbol="sh600000", start_date="20250212", end_date="20260212")
class MyStrategy(Strategy):
def on_bar(self, bar):
# 简单策略示例:
# 当收盘价 > 开盘价 (阳线) -> 买入
# 当收盘价 < 开盘价 (阴线) -> 卖出
# 获取当前持仓
current_pos = self.get_position(bar.symbol)
if current_pos == 0 and bar.close > bar.open:
self.buy(symbol=bar.symbol, quantity=100)
print(f"[{bar.timestamp_str}] Buy 100 at {bar.close:.2f}")
elif current_pos > 0 and bar.close < bar.open:
self.close_position(symbol=bar.symbol)
print(f"[{bar.timestamp_str}] Sell 100 at {bar.close:.2f}")
# 运行回测
result = aq.run_backtest(
data=df,
strategy=MyStrategy,
initial_cash=100000.0,
symbol="sh600000"
)
# 打印回测结果
print("\n=== Backtest Result ===")
print(result)
运行结果示例:

流式回测 (Streaming)
如果你希望在回测执行过程中实时消费事件,可使用 run_backtest_stream:
def on_event(event):
if event["event_type"] == "finished":
payload = event["payload"]
print("status:", payload.get("status"))
print("callback_error_count:", payload.get("callback_error_count"))
result = aq.run_backtest_stream(
data=df,
strategy=MyStrategy,
symbol="sh600000",
on_event=on_event,
show_progress=False,
stream_progress_interval=10,
stream_equity_interval=10,
stream_batch_size=32,
stream_max_buffer=256,
stream_error_mode="continue",
)
run_backtest 也支持可选 on_event。如果不传,框架会使用内部 no-op 回调,
保持与传统阻塞调用一致的返回语义;如果传入 on_event,即可在保持
run_backtest(...) 调用方式不变的同时接入实时事件。
关键参数:
stream_progress_interval/stream_equity_interval: 进度与权益事件采样间隔stream_batch_size/stream_max_buffer: 缓冲与批量刷新控制stream_error_mode: 回调异常策略,支持"continue"与"fail_fast"
阶段 5 迁移 FAQ:
run_backtest是否改名?不改名,调用方式保持不变。run_backtest是否还能不传on_event?可以,不传时仍返回同样的结果对象语义。- 如何回滚?阶段 5 后不再支持
_engine_mode参数级回滚,建议使用版本级回滚。 - 文档入口在哪里?可从 中文文档首页的阶段 5 迁移入口 快速跳转到 quickstart FAQ 和 API 兼容说明。
- 英文入口在哪里?可从 English docs Quick Links 跳转到 Phase-5 Migration FAQ 与 Compatibility Notes。
可视化 (Visualization)
AKQuant 内置了基于 Plotly 的强大可视化模块,仅需一行代码即可生成包含权益曲线、回撤分析、月度热力图等详细指标的交互式 HTML 报告。
# 生成交互式 HTML 报告,自动在浏览器中打开
result.report(
show=True,
compact_currency=True, # 金额列按 K/M/B 紧凑显示(默认 True)
)
# 如果你希望金额列保留原始数值精度(不缩写),可关闭:
result.report(
show=False,
filename="report_raw_amount.html",
compact_currency=False,
)
你也可以直接复用结构化分析结果做二次研究:
exposure = result.exposure_df() # 暴露分解(净暴露/总暴露/杠杆)
attr_by_symbol = result.attribution_df(by="symbol")
attr_by_tag = result.attribution_df(by="tag")
capacity = result.capacity_df() # 容量代理(成交率/换手等)
