使用 QKA（快量化）框架生成 A 股量化回测策略、选股和技术指标代码。当需要基于 qka.Data、qka.Strategy、qka.Backtest、qka.Broker 等 API 编写量化代码时使用此技能。.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# QKA 框架

简洁易用的 A 股量化回测框架，共七个公开类：

| 类 | 全限定名 | 作用 |
|-----|------|------|
| Data | `qka.Data` | 行情数据加载 + 指标预计算 |
| Simulate | `qka.Simulate` | 模拟标的 — 描述一只由 qka 现场生成的行情 |
| Strategy | `qka.Strategy` | 策略基类 — 实现 `on_bar` 做交易决策 |
| Broker | `qka.Broker` | 虚拟券商 — 执行买卖，管理资金和持仓 |
| SizingAccessor | `qka.SizingAccessor` | 仓位计算 — 四种仓位方法 |
| Backtest | `qka.Backtest` | 回测引擎 — 串联 Data 和 Strategy，注入基础设施 |
| Analysis | `qka.Analysis` | 分析模块 — 常用的分析方法 |

详细 API 文档按模块拆分在 `references/` 目录下，按需查阅对应文件：

| 模块 | 文件 | 内容 |
|------|------|------|
| Data | `references/data.md` | 数据加载、指标预计算（ta 库全部指标 + qka 内置指标）、`get()` |
| Simulate | `references/data.md` | 模拟标的：`Simulate(symbol, drift, reversion, vol)`，放进 `Data(symbols=[...])` |
| Strategy | `references/strategy.md` | 策略基类、`on_bar`、`self.get()`、`self.history()` |
| Backtest | `references/backtest.md` | `run()`、`bt.metrics`、`bt.results`、`bt.trade_history` |
| Broker | `references/broker.md` | `buy()`、`sell()` |
| SizingAccessor | `references/sizing.md` | 四种仓位方法 |
| Analysis | `references/analysis.md` | `zigzag()`、`alpha_beta()`、`sharpe_ratio()`、`max_drawdown()`、`information_ratio()` |

How to install

The exact contents, by fingerprint
mdr add zsrl/qka/qka@sha256:95d75dfc9bc6674c

The line at the top of this page pins the label git:20260916.c6d6560, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
