[Sensitive Data Protection](#sensitive-data-protection) +9. [Code Review Checklist](#code-review-checklist) + +--- + +## SOLID Principles + +All code must comply with SOLID design principles: + +### 1. Single Responsibility Principle (SRP) +- Each class should have only one reason to change +- Methods should perform a single, well-defined task +- Example: `AnalysisService` handles statistical analysis only, not data fetching + +### 2. Open/Closed Principle (OCP) +- Classes should be open for extension but closed for modification +- Use interfaces and abstract classes to enable extensibility +- Example: `IBrokerService` interface allows adding new brokers without modifying existing code + +### 3. Liskov Substitution Principle (LSP) +- Derived classes must be substitutable for their base classes +- Do not violate base class contracts in derived implementations +- Example: All broker implementations must honor the `ExchangeEnvironment` property contract + +### 4. Interface Segregation Principle (ISP) +- Clients should not be forced to depend on interfaces they do not use +- Prefer multiple small, specific interfaces over large, general-purpose ones +- Example: Separate `IHistoricalDataSourceService` and `IRealtimeDataSourceService` instead of one monolithic interface + +### 5. Dependency Inversion Principle (DIP) +- High-level modules should not depend on low-level modules +- Depend on abstractions, not concretions +- Example: Services depend on `IConfiguration` abstraction, not concrete configuration implementations + +--- + +## XML Documentation Standards + +### Rule: All public members must have bilingual (Chinese + English) XML documentation + +#### Format Template + +```csharp +/// +/// 方法的中文描述。 +/// English description of the method. +/// +/// 参数的中文说明 / English parameter description. +/// 返回值的中文说明 / English return value description. +/// 当参数无效时抛出 / Thrown when parameter is invalid. +``` + +#### Examples + +**Good:** +```csharp +/// +/// 计算两个时间序列的 Pearson 相关性。 +/// Calculates the Pearson correlation between two time series. +/// +/// 时间序列A / Time series A. +/// 时间序列B / Time series B. +/// 相关性系数 / The correlation coefficient. +/// 当参数为 null 时抛出 / Thrown when parameters are null. +public double CalculateCorrelation(IEnumerable seriesA, IEnumerable seriesB) +``` + +**Bad:** +```csharp +// Missing XML documentation +public double CalculateCorrelation(IEnumerable seriesA, IEnumerable seriesB) +``` + +#### Requirements +- Every `public` class, interface, method, property, and field must have XML documentation +- Both Chinese and English descriptions are mandatory +- Use consistent formatting: Chinese first, then English separated by "/" +- Document all parameters, return values, and exceptions + +--- + +## Parameter Validation + +### Rule: All public methods must validate parameters at the beginning + +#### Validation Patterns + +**Null Checks:** +```csharp +if (param == null) + throw new ArgumentNullException(nameof(param)); +``` + +**String Validation:** +```csharp +if (string.IsNullOrWhiteSpace(param)) + throw new ArgumentException("Parameter must not be null or empty.", nameof(param)); +``` + +**Range Validation:** +```csharp +if (param <= 0) + throw new ArgumentOutOfRangeException(nameof(param), "Parameter must be positive."); +``` + +**Date Validation:** +```csharp +if (startDt > endDt) + throw new ArgumentException("Start date must be earlier than or equal to end date.", nameof(startDt)); +``` + +#### Complete Example + +```csharp +public async Task> GetOhlcvListAsync(string symbol, DateTime startDt, DateTime endDt) +{ + // Parameter validation - MUST be at the beginning + if (string.IsNullOrWhiteSpace(symbol)) + throw new ArgumentException("Symbol must not be null or empty.", nameof(symbol)); + if (startDt > endDt) + throw new ArgumentException("Start date must be earlier than or equal to end date.", nameof(startDt)); + + // Business logic follows... +} +``` + +#### Error Message Standards +- All error messages must be in **English** to prevent encoding issues +- Include the parameter name using `nameof()` operator +- Be specific about what validation failed + +--- + +## Coding Language Standards + +### Rule: All runtime output must be in English + +#### Scope +- `Console.WriteLine()` messages +- Log messages (`Log.Information()`, `Log.Error()`, etc.) +- Exception messages +- User-facing strings + +#### Examples + +**Good:** +```csharp +Console.WriteLine($"Window is full, total {window.Count} elements"); +Log.Error("Download failed, please check network connection"); +throw new InvalidOperationException("CoinMarketCap: Response missing status field."); +``` + +**Bad:** +```csharp +Console.WriteLine($"窗口已满，共 {window.Count} 个元素"); +Log.Error("下载失败，请检查网络连接"); +throw new InvalidOperationException("CoinMarketCap: 响应缺少 status 字段。"); +``` + +#### Rationale +- Prevents character encoding issues (乱码) +- Ensures compatibility across different systems and locales +- Facilitates international collaboration + +#### Exception +- **Code comments** should remain bilingual (Chinese + English) for better understanding by Chinese developers + +--- + +## Time Handling Standards + +### Rule: All database operations and persistence must use UTC time + +#### Guidelines + +**Use `DateTime.UtcNow`:** +```csharp +var timestamp = DateTime.UtcNow; // ✅ Correct +var record = new Record { CreatedAt = DateTime.UtcNow }; +``` + +**Avoid `DateTime.Now`:** +```csharp +var timestamp = DateTime.Now; // ❌ Wrong - uses local time +``` + +**Unix Timestamp Calculation:** +```csharp +// Correct way to calculate Unix timestamp +var timestamp = ((DateTime.UtcNow.Ticks - new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).Ticks) / 10000).ToString(); +``` + +#### Affected Areas +- Database timestamps +- File modification times +- API request/response timestamps +- Log timestamps +- Cache expiry times + +#### Rationale +- Ensures consistency across different time zones +- Prevents daylight saving time issues +- Simplifies time comparison and sorting + +--- + +## Enum Management + +### Rule: All enums must be centralized in `Shared/Model/Enums.cs` + +#### Requirements + +1. **Centralization**: No enums should be defined outside `Shared/Model/Enums.cs` +2. **Documentation**: Every enum and enum value must have bilingual XML documentation +3. **Naming**: Use PascalCase for enum names and values +4. **Explicit Values**: Always specify explicit integer values for enum members + +#### Example + +```csharp +/// +/// 交易所环境：测试网、实盘、模拟盘。 +/// Exchange environment: testnet, live, or paper trading. +/// +public enum ExchangeEnvironment +{ + /// + /// 测试网环境，用于开发和测试 / Testnet environment for development and testing. + /// + Testnet = 0, + + /// + /// 实盘环境，使用真实资金进行交易 / Live environment with real funds for trading. + /// + Live = 1, + + /// + /// 模拟盘环境，使用虚拟资金模拟实盘 / Paper trading environment with virtual funds simulating live trading. + /// + Paper = 2 +} +``` + +#### Current Enums +- `ExchangeEnvironment` - Trading environment types +- `StartMode` - Timer trigger modes +- `MarketType` - Market classifications +- `Broker` - Supported brokers +- `OrderStatus` - Order lifecycle states +- `AssetType` - Asset classifications +- `ResolutionLevel` - Time series resolutions +- `DataSource` - Data source providers +- `TradeDirection` - Long/Short positions +- `Currency` - Currency types +- And more... + +--- + +## README Maintenance + +### Rule: README.md must be updated synchronously with code changes + +#### Update Policy + +1. **Version History**: Add new entry for each release with: + - Version number (SemVer format: MAJOR.MINOR.PATCH) + - Release date (YYYY-MM-DD format) + - Concise description of changes + +2. **Bilingual Consistency**: Both English and Chinese sections must be updated simultaneously + +3. **API Changes**: Any change to public APIs must be reflected in: + - Quick Start section + - Usage scenarios + - Code examples + +4. **Structure Preservation**: Maintain standard Markdown formatting; do not restructure arbitrarily + +#### Example Version Entry + +```markdown +| 1.5.0 | 2024-06-01 | Added Schwab broker integration and enhanced error handling | +``` + +#### Last Updated +- Current version: 1.4.0 +- Last updated: 2024-05-16 + +--- + +## Sensitive Data Protection + +### Rule: Never commit sensitive data to GitHub + +#### Protected Files (in `.gitignore`) +- `appsettings.json` +- `appsettings.*.json` (except `appsettings.example.json`) +- `*.secret` +- `*.env` +- `secrets.json` + +#### Sensitive Data Types +- API keys and secrets +- Database connection strings +- Email credentials +- Broker authentication tokens +- Private keys and certificates + +#### Best Practices + +1. **Use Environment Variables**: + ```csharp + var apiKey = Environment.GetEnvironmentVariable("BINANCE_API_KEY"); + ``` + +2. **Use User Secrets (Development)**: + ```bash + dotnet user-secrets set "Exchange:ApiKey" "your-key-here" + ``` + +3. **Use Example Files**: + - Create `appsettings.example.json` with placeholder values + - Document required configuration structure + - Never include real credentials + +4. **Review Before Commit**: + - Check for accidental credential exposure + - Use pre-commit hooks if available + - Review git diff before pushing + +--- + +## Code Review Checklist +
