CarrotQuant
CarrotQuant 是高性能全栈量化交易、金融数据流水线与回测框架的主入口元包 (Umbrella Package),聚合了数据中台与回测内核两大核心组件。
🏗️ 架构全景
pip install carrotquant (默认安装全套能力)

📦 安装 (Installation)
环境要求:Python >= 3.12(支持 Python 3.12 / 3.13 / 3.14+)。
1. 默认安装 (推荐,开箱即用)
# 默认安装 carrotquant-engine 与 carrotquant-data 全套组件
pip install carrotquant
# 或使用 uv 安装
uv add carrotquant
2. 细分可选安装 (Extras)
# 仅安装核心回测引擎
pip install carrotquant[engine]
# 仅安装数据同步与 Web 终端
pip install carrotquant[data]
# 显式安装全套依赖
pip install carrotquant[all]
🚀 快速开始
1. 数据同步与 Web 终端管理
通过命令行工具 cqdata(安装 carrotquant 后自动就绪):
# 启动本地 Web 数据终端与 REST API 服务
cqdata server --port 8888 --open
# 触发 A 股日线数据自动增量同步
cqdata sync -t ashare.kline.1d.raw.baostock
2. 数据读取与策略回测全流程
# 方式 A:通过主元包分层结构化调用
import carrotquant as cq
# 1. (数据层) 读取本地清洗好的 Parquet/CSV 数据
df = cq.data.read(
table_id="ashare.kline.1d.raw.baostock",
symbols=["sh.600000", "sz.000001"],
start_date="2023-01-01",
end_date="2023-12-31"
)
# 2. (策略层) 定义事件驱动双均线策略
@cq.engine.strategy
def dual_ma_strategy(ctx: cq.engine.BarContext):
for i in range(ctx.n_symbols):
if not ctx.is_tradable[i]:
continue
# 读取后复权历史收盘价
c_hist = ctx.adj.close_history[-20:, i]
ma5 = c_hist[-5:].mean()
ma20 = c_hist[-20:].mean()
if ma5 > ma20 and ctx.positions[i] == 0:
ctx.buy(symbol_idx=i, amount=100)
elif ma5 < ma20 and ctx.positions[i] > 0:
ctx.sell(symbol_idx=i, amount=ctx.positions[i])
# 3. (引擎层) 初始化并启动 Numba 高性能回测
data_stream = cq.engine.ColumnDataLoader.scan_parquet_chunks(
path="data/parquet/ashare.kline.1d.raw.baostock",
partition_by="year"
)
engine = cq.engine.Engine(
initial_cash=1_000_000.0,
fee_rate=0.0003,
stamp_duty=0.0005,
slippage=0.0001,
matching_mode="close"
)
results = engine.run(strategy=dual_ma_strategy, data=data_stream)
# 4. (分析层) 输出绩效汇总与成交明细
print(results.summary())
print(results.trade_logs) # Polars DataFrame
方式 B:按需直接使用标准子命名空间导入:
from cq.data import read, ashare
from cq.engine import Engine, strategy, BarContext, ColumnDataLoader
