+## 项目结构
+
+```
+Mt5Bridge/
+├── Program.cs           # 全部代码（单文件 ASP.NET Core）
+├── Mt5Bridge.csproj     # 项目文件
+├── libs/                # MtApi5 依赖 DLL
+│   ├── MtApi5.dll
+│   ├── MtClient.dll
+│   └── Newtonsoft.Json.dll
+└── README.md
+```
+
+## 部署到其他机器
+
+1. 拷贝整个 `Mt5Bridge/` 文件夹
+2. 确保目标机器安装了 .NET 8 SDK
+3. 确保 MT5 客户端已登录 + MtApi5 EA 挂载在图表上
+4. `dotnet run` 即可启动
+
+## 修改端口
+
+编辑 `Program.cs` 第 5 行：
+
+```csharp
+builder.WebHost.UseUrls("http://localhost:8080");
+```
+
+将 `8080` 改为其他端口即可。
+
+## 连接超时
+
+当前 CommandTimeout 设为 120 秒（通过反射设置），适用于请求大量历史 K 线的场景。如需调整，修改 `Program.cs` 第 14 行即可。
+
+## 常见问题
+
+**Q: 启动后一直显示 "Connecting..."？**
+
+A: 确保 MT5 已打开并登录，且 MtApi5 EA 已挂载在任意图表上。EA 默认监听 8228 端口。
+
+**Q: 请求返回 500 错误？**
+
+A: 查看 Bridge 控制台输出的错误日志，常见原因：品种名不存在、MT5 断连、数据量过大超时。
+
+**Q: 能用在其他语言的项目中吗？**
+
+A: 可以。Bridge 是标准 HTTP REST API，任何语言的 HTTP 客户端都能调用。详见上方 API 文档。
