 # Repository Guidelines
 
-## Project Structure & Module Organization
+## Package Manager
-The Bun entry point (`index.ts`) lives at the repo root for quick CLI smoke checks. All production code is under `src/`:
 
-- `src/strategy/` gathers every live trading engine (`maker`, `offset-maker`, `trend`). Shared helpers for strategy wiring sit in `src/strategy/common/`.
+**必须使用 Bun** — 本项目使用 Bun 作为包管理器和运行时。所有命令都必须用 bun 执行，**不要使用 npm、yarn 或 npx**。
-- `src/core/` keeps order coordination plus shared libs used by multiple strategies.
-- `src/exchanges/` exposes the adapters and REST/websocket clients.
-- `src/ui/` implements the Ink dashboards for each strategy (they remain independent dashboards).
-- `src/logging/` contains the trade log helper.
-- `src/utils/` and `src/config.ts` hold cross-cutting utilities and runtime config.
-- `docs/` stores reference material, while `tests/` contains Vitest suites.
 
-## Build, Test, and Development Commands
+## Project Structure
-- `bun install` – install dependencies.
-- `bun run index.ts` – launch the CLI menu.
-- `bun x vitest run` – execute the full test suite; `bun x vitest --watch` for incremental runs.
 
-Strategy-specific scripts still execute through the CLI; there is no separate `legacy/` workspace.
+入口 `index.ts` 在仓库根目录，用于 CLI 启动。所有生产代码在 `src/` 下：
 
-## Coding Style & Naming Conventions
+```
-Use modern TypeScript with ES modules, two-space indentation, and sorted imports (external → internal). Favor `camelCase` for variables/functions and `PascalCase` for classes/enums. Place new strategies under `src/strategy/`, shared utilities under `src/utils/` or `src/strategy/common/` when they only apply to strategies. Keep comments focused on non-obvious trading logic.

-## Testing Guidelines
+辅助目录：
-Vitest powers unit/integration tests. Co-locate new tests next to their subject using `<feature>.test.ts`. Strategies should have coverage for order lifecycle, risk guards, and websocket edge cases. Run `bun x vitest --watch` during development for fast feedback.
+- `tests/` — Vitest 测试套件（大部分测试在此，少量与逻辑共处于 `src/`）
+- `docs/` — 交易所 API 参考文档
+- `scripts/` — 一次性脚本（密钥派生等）
+- `skills/` — AI 助手技能配置
 
-## Commit & Pull Request Guidelines
+## Commands
-Follow lightweight Conventional Commits (e.g. `feat: add hedging status panel`). Scope each commit to a single module or strategy. PRs should include:
+
-- Summary of changes.
+```bash
-- Validation notes (commands run, environments touched).
+bun install                  # 安装依赖
-- Relevant logs or screenshots for behavior changes.
+bun run dev                  # 启动 CLI 菜单（等同于 bun run index.ts）
-Link issues/tasks when available.
+bun run test                 # 执行全部测试（bun x vitest run）
+bun x vitest --watch         # 增量测试
+bun x tsc --noEmit           # 类型检查（无 typecheck 脚本，直接用 tsc）
+bun run lint                 # oxlint 检查
+bun run lint:fix             # oxlint 自动修复
+```
+
+⚠️ **不要用 `bun test`** — 那是 Bun 内置 runner，不支持 `vi.resetModules()`、`vi.waitFor()` 等 Vitest API。必须用 `bun run test`。
+
+## Coding Style
+
+- 现代 TypeScript + ES modules，严格模式（`strict: true`）
+- 两空格缩进，imports 按 external → internal 排序
+- 变量/函数用 `camelCase`，类/枚举用 `PascalCase`
+- 新策略放 `src/strategy/`，策略共享工具放 `src/strategy/common/`
+- 跨领域工具放 `src/utils/`
+- 注释只写非显而易见的交易逻辑
+- JSX 用于 Ink UI 组件（`react-jsx`）
+
+## Testing
+
+Vitest 驱动所有测试。测试文件两种位置：
+- `tests/<feature>.test.ts` — 大部分测试
+- `src/<module>/<feature>.test.ts` — 纯逻辑单元测试（如 `maker-points-logic.test.ts`、`swing-logic.test.ts`）
+
+策略测试应覆盖：订单生命周期、风控守卫、WebSocket 边界情况、状态恢复。
+
+## Commit Guidelines
+
+Conventional Commits（`feat:` / `fix:` / `refactor:` / `test:`），每次提交作用域限单个模块或策略。
 
 ## Environment & Secrets
-Duplicate `.env.example` to `.env` and populate API keys (Aster/GRVT) before running strategies. Do not commit secrets—use local `.env` or deployment secret managers. Rotate keys if they leak into logs or backups.
+
+复制 `.env.example` 为 `.env` 填入 API 密钥。**不要读取、打印或提交 `.env` 和任何密钥。** 泄露立即轮换。
+
+## Safety
+
+- 永远不要读取、运行、打印或访问 `.env` 或任何 secrets
+- 代码中遇到项目依赖时，先查版本再查文档，避免过时知识导致错误

+# Ondo Perps 接入说明
+
+## 链接
+
+- 邀请注册：https://app.ondoperps.xyz/?ref=4A3ACQ
+- 官方文档索引：https://ondoperps.mintlify.app/llms.txt
+- REST OpenAPI：https://docs.ondoperps.xyz/api-reference/rest-spec.json
+- WebSocket OpenAPI：https://docs.ondoperps.xyz/api-reference/ws-spec.json
+- API Key 鉴权：https://docs.ondoperps.xyz/api-reference/api_key_authentication.md
+
+## 配置
+
+```bash
+EXCHANGE=ondoperps
+ONDOPERPS_API_KEY_ID=ondoKeyId_xxx
+ONDOPERPS_API_SECRET=ondoApiSecret_xxx
+ONDOPERPS_SYMBOL=BTC-USD.P
+```
+
+Ondo Perps 市场使用 `{TICKER}-USD.P` 格式。默认值为 `BTC-USD.P`，其他示例包括 `ETH-USD.P`、`XAU-USD.P`、`NVDA-USD.P` 与 `AMD-USD.P`。
+
+兼容入口：`EXCHANGE=ondoperp` 会解析为 `ondoperps`，旧 `ONDOPERP_*` 环境变量会在对应 `ONDOPERPS_*` 变量缺失时使用。
+
+可选配置：
+
+| 变量 | 说明 |
+| --- | --- |
+| `ONDOPERPS_SANDBOX` | `true` 时连接官方沙盒 REST 与 WebSocket 地址 |
+| `ONDOPERPS_BASE_URL` | 覆盖 REST API 地址 |
+| `ONDOPERPS_WS_URL` | 覆盖 WebSocket 地址 |
+| `ONDOPERPS_BUILDER_CODE` | Ondo 分配的 Builder Code |
+| `ONDOPERPS_BUILDER_FEE_RATE_BPS` | Builder 订单费率，适配器限制在 1–10 bps |
+
+## 已接入能力
+
+- API Key HMAC-SHA256 REST 鉴权
+- 限价单、Post Only 限价单、市价单、批量撤单与全部撤单
+- 仓位级止损与止盈，映射到统一订单类型
+- 账户余额、仓位、活动订单与市场精度查询
+- 深度、标记价、K 线、资金费率、订单、仓位与余额 WebSocket 订阅
+- REST 定时校准，覆盖 WebSocket 断线和私有频道鉴权异常场景
+- 生产与沙盒端点切换
+
+## 鉴权规则
+
+REST 请求发送以下请求头：
+
+- `ONDO-KEY-ID`
+- `ONDO-TIMESTAMP`
+- `ONDO-SIGN`
+
+签名内容为 `timestamp + uppercaseMethod + requestPathWithQuery + body`，使用 API Secret 进行 HMAC-SHA256 并输出十六进制字符串。
+
+WebSocket 登录消息使用 API Key ID、毫秒时间戳与 `time + "ondo_perps_ws_login"` 的 HMAC-SHA256 签名。连接空闲限制为 180 秒，适配器每 30 秒发送一次 ping。
+
+## 安全
+
+API Secret 只通过运行环境传入。仓库文件、日志与错误信息均不保存请求签名头或凭证内容。建议在 Ondo Perps 后台配置固定 IPv4 白名单，并为 API Key 只授予策略需要的权限。
