+# Managing Apps - Claude Code Guidelines
 
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+## Project Overview
+This is a quantitative finance application with .NET backend and React TypeScript frontend, focusing on algorithmic trading, market indicators, and financial mathematics.
 
-## Common Development Commands
+## Core Architecture Principles
 
-### Backend (.NET)
+### Quantitative Finance Requirements
+- **IMPORTANT**: Use `decimal` for all monetary calculations (never `double` or `float`)
+- Implement proven financial mathematics (Black-Scholes, Monte Carlo, etc.)
+- Optimize time-series processing for tick data/OHLCV series
+- Validate models with historical backtesting frameworks
+- Maintain audit trails for all financial calculations
+- Prioritize numerical precision in all calculations
+
+### Backend (.NET/C#) Guidelines
+
+#### Code Style and Structure
+- Write concise, idiomatic C# code following .NET conventions
+- Use object-oriented and functional programming patterns appropriately
+- Prefer LINQ and lambda expressions for collection operations
+- Use descriptive variable and method names (e.g., `IsUserSignedIn`, `CalculateTotal`)
+- Structure files according to .NET conventions (Controllers, Models, Services, etc.)
+
+#### Naming Conventions
+- **PascalCase**: Class names, method names, public members
+- **camelCase**: Local variables, private fields
+- **UPPERCASE**: Constants
+- **Prefix interfaces with "I"**: `IUserService`, `IAccountRepository`
+
+#### C# and .NET Usage
+- Use C# 10+ features (record types, pattern matching, null-coalescing assignment)
+- Leverage built-in ASP.NET Core features and middleware
+- Use `var` for implicit typing when type is obvious
+- Use MongoDb and Influxdb for database operations
+
+#### Architecture Layers (YOU MUST FOLLOW)
+1. **Controller** → **Application** → **Repository** (NEVER inject repository in controllers)
+2. Always implement methods you create
+3. Check existing code before creating new objects/methods
+4. Update all layers when necessary (database to frontend)
+
+#### Error Handling and Validation
+- Use exceptions for exceptional cases, not control flow
+- Implement proper error logging with .NET logging
+- Use Data Annotations or Fluent Validation for model validation
+- Return appropriate HTTP status codes and consistent error responses
+- Services in `services/` directory must throw user-friendly errors for tanStackQuery
+
+#### API Design
+- Follow RESTful API design principles
+- Use attribute routing in controllers
+- Implement versioning for APIs
+- Use Swagger/OpenAPI for documentation
+
+#### Performance Optimization
+- Use `async/await` for I/O-bound operations
+- Implement caching strategies (IMemoryCache or distributed caching)
+- Use efficient LINQ queries, avoid N+1 query problems
+- Implement pagination for large datasets
+
+### Frontend (React/TypeScript) Guidelines
+
+#### Component Structure
+- Use functional components with TypeScript interfaces
+- Use declarative JSX
+- Use `function`, not `const` for components
+- Use DaisyUI Tailwind Aria for components and styling
+- Implement responsive design with Tailwind CSS (mobile-first approach)
+
+#### File Organization
+- Use lowercase with dashes for directories: `components/auth-wizard`
+- Place static content and interfaces at file end
+- Use content variables for static content outside render functions
+- Favor named exports for components
+
+#### State Management
+- Minimize `use client`, `useEffect`, and `setState`
+- Favor React Server Components (RSC)
+- Wrap client components in Suspense with fallback
+- Use dynamic loading for non-critical components
+- Use `useActionState` with react-hook-form for form validation
+
+#### Error Handling
+- Model expected errors as return values (avoid try/catch for expected errors)
+- Use error boundaries for unexpected errors (`error.tsx`, `global-error.tsx`)
+- Use `useActionState` to manage errors and return them to client
+
+#### Component Library
+- **DO NOT** reference new React libraries if components exist in `mollecules` or `atoms`
+- Check existing components before creating new ones
+
+## Development Workflow
+
+### Build and Run Commands
 ```bash
-# Build entire solution
-dotnet build src/Managing.sln
+# Backend
+dotnet build
+dotnet run --project src/Managing.Api
 
-# Run main API (port 80/443)
-dotnet run --project src/Managing.Api/Managing.Api.csproj
+# Frontend
+npm run build
+npm run dev
 
-# Run worker API (port 81/444)
-dotnet run --project src/Managing.Api.Workers/Managing.Api.Workers.csproj
-
-# Run tests
-dotnet test src/Managing.Application.Tests/
-dotnet test src/Managing.Infrastructure.Tests/
-
-# Run specific test
-dotnet test --filter "TestMethodName"
-
-# Database migrations
-dotnet ef database update --project src/Managing.Infrastructure.Database/Managing.Infrastructure.Databases.csproj --context ManagingDbContext
-dotnet ef migrations add <MigrationName> --project src/Managing.Infrastructure.Database/Managing.Infrastructure.Databases.csproj --context ManagingDbContext
-
-# Regenerate API client (after API changes)
+# Regenerate API client (after backend changes)
 cd src/Managing.Nswag && dotnet build
 ```
 
-### Frontend (React/TypeScript)
-```bash
-cd src/Managing.WebApp
+### API Client Generation
+1. **NEVER** update `ManagingApi.ts` manually
+2. After backend endpoint changes:
+   - Run the Managing.Api project
+   - Execute: `cd src/Managing.Nswag && dotnet build`
+   - This regenerates `ManagingApi.ts` automatically
 
-# Install dependencies
-npm install
+### Testing
+- Write unit tests using xUnit for backend
+- Use Mock or NSubstitute for mocking dependencies
+- Implement integration tests for API endpoints
 
-# Development server
-npm run dev
+## Security Guidelines
+- **IMPORTANT**: Handle sensitive data carefully (API keys, private keys, etc.)
+- Implement proper authentication and authorization
+- Use secure communication protocols
+- Validate all user inputs
 
-# Build for production
-npm run build
+## Database Guidelines
+- Use PostgreSQL for relational data
+- Use InfluxDB for time-series data (candles, metrics)
+- Use MongoDB for document storage
+- Implement proper migrations
 
-# Linting and type checking
-npm run lint
-npm run typecheck
+## Orleans Integration (Co-Hosting)
+- Use `IGrainFactory` instead of `IClusterClient` for co-hosting scenarios
+- Orleans automatically provides `IGrainFactory` when using `UseOrleans()`
+- Avoid circular dependency issues by not manually registering `IClusterClient`
+- Use Orleans grains for high-availability trading bots
 
-# Tests
-npm run test
+## Common Patterns
+
+### Backend Service Pattern
+```csharp
+public class ExampleService : IExampleService
+{
+    private readonly IExampleRepository _repository;
+    private readonly ILogger<ExampleService> _logger;
+
+    public ExampleService(IExampleRepository repository, ILogger<ExampleService> logger)
+    {
+        _repository = repository;
+        _logger = logger;
+    }
+
+    public async Task<Example> CreateExampleAsync(ExampleRequest request)
+    {
+        // Implementation
+    }
+}
 ```
 
-### Full Stack Development
-```bash
-# Quick start with Docker
-./scripts/build_and_run.sh
+### Frontend Component Pattern
+```typescript
+interface ComponentProps {
+  isLoading: boolean;
+  data: SomeType[];
+}
 
-# Alternative using Aspire
-cd src && ./run-aspire.sh
+function Component({ isLoading, data }: ComponentProps): JSX.Element {
+  if (isLoading) return <Loader />;
+  
+  return (
+    <div className="container mx-auto">
+      {/* Component content */}
+    </div>
+  );
+}
+
+export default Component;
 ```

+```
 
-### Clean Architecture Pattern
-The codebase follows Clean Architecture with clear layer separation:
-- **Domain** (`Managing.Domain`): Business entities and core rules
-- **Application** (`Managing.Application*`): Use cases, commands, and business orchestration  
-- **Infrastructure** (`Managing.Infrastructure.*`): External integrations (databases, Web3, messaging)
-- **Presentation** (`Managing.Api*`): REST APIs and controllers
-
-### Service Architecture
-Multiple coordinated services handle different concerns:
-- **Managing.Api**: Main trading operations, bot management, backtesting
-- **Managing.Api.Workers**: Background workers for price data, genetic algorithms, statistics
-- **Managing.Web3Proxy**: Node.js service for Web3/GMX blockchain interactions
-- **Managing.WebApp**: React frontend with real-time SignalR updates
-
-### Data Storage Strategy (Polyglot Persistence)
-- **PostgreSQL**: Transactional data (users, bots, positions, scenarios, backtests)
-- **InfluxDB**: Time-series data (OHLCV candles, agent balances, performance metrics)
-- **MongoDB**: Document storage for certain data types
-
-### Key Domain Concepts
-- **Bot**: Abstract base with lifecycle management for trading automation
-- **Position**: Trading positions with PnL tracking and trade history
-- **Scenario**: Collections of technical indicators defining trading strategies
-- **Indicator**: Technical analysis tools (RSI, MACD, EMA, SuperTrend, etc.)
-- **MoneyManagement**: Risk parameters (stop loss, take profit, position sizing)
-- **Account**: Multi-exchange trading accounts (CEX, GMX V2, Privy wallets)
-
-## Development Patterns
-
-### Adding New Features
-1. **Domain First**: Create entities in `Managing.Domain`
-2. **Application Layer**: Add services/command handlers in `Managing.Application`
-3. **Infrastructure**: Implement repositories and external integrations
-4. **API Layer**: Add controllers and endpoints
-5. **Frontend**: Update React components and API client
-
-### Bot Development
-- Inherit from `Bot` base class in `Managing.Domain/Bots/`
-- Implement `SaveBackup()` and `LoadBackup()` for persistence
-- Use dependency injection pattern for services
-- Follow worker pattern for background execution
-
-### Adding Technical Indicators
-1. Create indicator class implementing `IIndicator`
-2. Add to `IndicatorType` enum in `Managing.Common`
-3. Register in DI container via `ApiBootstrap`
-4. Implement calculation logic in `TradingService`
-
-### Database Changes
-1. Update entities in domain layer
-2. Modify `ManagingDbContext` with new DbSets
-3. Generate EF Core migration
-4. Update repository interfaces and implementations
-5. Consider InfluxDB for time-series data
-
-### Web3 Integration
-- GMX V2 interactions go through `Managing.Web3Proxy` Node.js service
-- Use `Managing.Infrastructure.Web3` for .NET integration
-- Privy handles wallet management and authentication
-
-## Configuration & Environment
-
-### Key Configuration Files
-- `src/Managing.Api/appsettings.*.json`: Main API configuration
-- `src/Managing.Api.Workers/appsettings.*.json`: Worker configuration
-- `src/Managing.WebApp/.env`: Frontend environment variables
-
-### Environment-Specific Deployments
-- Development: `appsettings.Development.json`
-- Sandbox: `appsettings.Sandbox.json`
-- Production: `appsettings.Production.json`
-- Docker: `appsettings.Oda-docker.json`
-
-## Important Development Guidelines
-
-### Quantitative Finance Principles
-- Use `decimal` for all monetary calculations (never `float` or `double`)
-- Implement proper audit trails for financial operations
-- Validate trading strategies with historical backtesting
-- Optimize time-series processing for performance
-
-### Code Architecture Rules
-- Follow Controller → Application → Repository pattern (never inject repositories directly into controllers)
-- Use CQRS pattern with command handlers for complex operations
-- Implement proper error handling with user-friendly messages
-- Maintain separation between domain logic and infrastructure concerns
-
-### API Development
-- Follow RESTful conventions
-- Use attribute routing in controllers
-- Return appropriate HTTP status codes
-- Implement proper validation using Data Annotations
-
-### Testing Strategy
-- Unit tests focus on domain logic and indicators
-- Integration tests for external service interactions
-- Use data-driven testing with JSON fixtures for backtesting scenarios
-
-## Real-time Features
-- SignalR hubs provide live updates for trading data, bot status, and market information
-- Frontend uses reactive patterns with real-time price feeds and position updates
+## Important Reminders
+- Always implement methods you create
+- Check existing code before creating new functionality
+- Update multiple layers when necessary
+- Build project after finishing edits
+- Follow the controller → application → repository pattern
+- Use existing components in mollecules/atoms before adding new libraries
+- Use `IGrainFactory` for Orleans co-hosting (not `IClusterClient`)

+# Orleans Migration Plan for Managing Apps Trading Bot
+
+## Overview
+Migrate the `TradingBot` class to Microsoft Orleans grains for improved performance, scalability, and high availability while maintaining backward compatibility with the `Backtester` class.
+
+## Current Architecture Analysis
+
+### TradingBot Key Characteristics
+- Long-running stateful service with complex state (positions, signals, candles, indicators)
+- Timer-based execution via `InitWorker(Run)` 
+- Dependency injection via `IServiceScopeFactory`
+- Persistence via `SaveBackup()` and `LoadBackup()`
+- SignalR integration for real-time updates
+
+### Backtester Requirements
+- Creates TradingBot instances as regular classes (line 198: `_botFactory.CreateBacktestTradingBot`)
+- Runs synchronous backtesting without Orleans overhead
+- Needs direct object manipulation for performance
+
+## 1. Orleans Grain Design
+
+### A. Create ITradingBotGrain Interface
+```csharp
+// src/Managing.Application.Abstractions/Grains/ITradingBotGrain.cs
+public interface ITradingBotGrain : IGrainWithStringKey
+{
+    Task StartAsync();
+    Task StopAsync();
+    Task<BotStatus> GetStatusAsync();
+    Task<TradingBotConfig> GetConfigurationAsync();
+    Task<bool> UpdateConfigurationAsync(TradingBotConfig newConfig);
+    Task<Position> OpenPositionManuallyAsync(TradeDirection direction);
+    Task ToggleIsForWatchOnlyAsync();
+    Task<TradingBotResponse> GetBotDataAsync();
+    Task LoadBackupAsync(BotBackup backup);
+}
+```
+
+### B. Modify TradingBot Class
+```csharp
+// src/Managing.Application/Bots/TradingBot.cs
+public class TradingBot : Grain, ITradingBotGrain, ITradingBot
+{
+    // Keep existing implementation but add Orleans-specific methods
+    // Add grain lifecycle management
+    // Replace IServiceScopeFactory with Orleans DI
+}
+```
+
+## 2. Program.cs Orleans Configuration
+
+Add to `src/Managing.Api/Program.cs` after line 188:
+
+```csharp
+// Orleans Configuration
+builder.Host.UseOrleans(siloBuilder =>
+{
+    siloBuilder
+        .UseLocalhostClustering() // For local development
+        .ConfigureLogging(logging => logging.AddConsole())
+        .UseDashboard(options => { options.Port = 8080; })
+        .AddMemoryGrainStorageAsDefault()
+        .ConfigureServices(services =>
+        {
+            // Register existing services for Orleans DI
+            services.AddSingleton<IExchangeService, ExchangeService>();
+            services.AddSingleton<IAccountService, AccountService>();
+            services.AddSingleton<ITradingService, TradingService>();
+            services.AddSingleton<IMessengerService, MessengerService>();
+            services.AddSingleton<IBackupBotService, BackupBotService>();
+        });
+
+    // Production clustering configuration
+    if (builder.Environment.IsProduction())
+    {
+        siloBuilder
+            .UseAdoNetClustering(options =>
+            {
+                options.ConnectionString = postgreSqlConnectionString;
+                options.Invariant = "Npgsql";
+            })
+            .UseAdoNetReminderService(options =>
+            {
+                options.ConnectionString = postgreSqlConnectionString;
+                options.Invariant = "Npgsql";
+            });
+    }
+});
+
+// Orleans Client Configuration (for accessing grains from controllers)
+builder.Services.AddOrleansClient(clientBuilder =>
+{
+    clientBuilder.UseLocalhostClustering();
+    
+    if (builder.Environment.IsProduction())
+    {
+        clientBuilder.UseAdoNetClustering(options =>
+        {
+            options.ConnectionString = postgreSqlConnectionString;
+            options.Invariant = "Npgsql";
+        });
+    }
+});
+```
+
+## 3. Conditional Bot Instantiation Strategy
+
+### A. Enhanced BotFactory Pattern
+```csharp
+// src/Managing.Application/Bots/Base/BotFactory.cs
+public class BotFactory : IBotFactory
+{
+    private readonly IClusterClient _clusterClient;
+    private readonly IServiceProvider _serviceProvider;
+
+    public async Task<ITradingBot> CreateTradingBotAsync(TradingBotConfig config, bool useGrain = true)
+    {
+        if (config.IsForBacktest || !useGrain)
+        {
+            // For backtesting: Create regular class instance
+            return new TradingBot(
+                _serviceProvider.GetService<ILogger<TradingBot>>(),
+                _serviceProvider.GetService<IServiceScopeFactory>(),
+                config
+            );
+        }
+        else
+        {
+            // For live trading: Use Orleans grain
+            var grain = _clusterClient.GetGrain<ITradingBotGrain>(config.Name);
+            return new TradingBotGrainProxy(grain, config);
+        }
+    }
+}
+```
+
+### B. TradingBotGrainProxy (Adapter Pattern)
+```csharp
+// src/Managing.Application/Bots/TradingBotGrainProxy.cs
+public class TradingBotGrainProxy : ITradingBot
+{
+    private readonly ITradingBotGrain _grain;
+    private TradingBotConfig _config;
+
+    public TradingBotGrainProxy(ITradingBotGrain grain, TradingBotConfig config)
+    {
+        _grain = grain;
+        _config = config;
+    }
+
+    public async Task Start() => await _grain.StartAsync();
+    public async Task Stop() => await _grain.StopAsync();
+    
+    // Implement all ITradingBot methods by delegating to grain
+    // This maintains compatibility with existing bot management code
+}
+```
+
+### C. Backtester Compatibility
+In `Backtester.cs` (line 198), the factory call remains unchanged:
+```csharp
+// This will automatically create a regular class instance due to IsForBacktest = true
+var tradingBot = await _botFactory.CreateBacktestTradingBot(config);
+```
+
+## 4. Orleans Grain State Management
+
+```csharp
+// src/Managing.Application/Bots/TradingBotGrainState.cs
+[GenerateSerializer]
+public class TradingBotGrainState
+{
+    [Id(0)] public TradingBotConfig Config { get; set; }
+    [Id(1)] public HashSet<LightSignal> Signals { get; set; }
+    [Id(2)] public List<Position> Positions { get; set; }
+    [Id(3)] public Dictionary<DateTime, decimal> WalletBalances { get; set; }
+    [Id(4)] public BotStatus Status { get; set; }
+    [Id(5)] public DateTime StartupTime { get; set; }
+    [Id(6)] public DateTime CreateDate { get; set; }
+}
+
+// Updated TradingBot grain
+public class TradingBot : Grain<TradingBotGrainState>, ITradingBotGrain
+{
+    private IDisposable _timer;
+
+    public override async Task OnActivateAsync(CancellationToken cancellationToken)
+    {
+        // Initialize grain state and start timer-based execution
+        if (State.Config != null && State.Status == BotStatus.Running)
+        {
+            await StartTimerAsync();
+        }
+    }
+
+    private async Task StartTimerAsync()
+    {
+        var interval = CandleExtensions.GetIntervalFromTimeframe(State.Config.Timeframe);
+        _timer = RegisterTimer(async _ => await Run(), null, TimeSpan.Zero, TimeSpan.FromMilliseconds(interval));
+    }
+}
+```
+
+## 5. Implementation Roadmap
+
+### Phase 1: Infrastructure Setup
+1. **Add Orleans packages** (already done in Managing.Api.csproj)
+2. **Configure Orleans in Program.cs** with clustering and persistence
+3. **Create grain interfaces and state classes**
+
+### Phase 2: Core Migration  
+1. **Create ITradingBotGrain interface** with async methods
+2. **Modify TradingBot class** to inherit from `Grain<TradingBotGrainState>`
+3. **Implement TradingBotGrainProxy** for compatibility
+4. **Update BotFactory** with conditional instantiation logic
+
+### Phase 3: Service Integration
+1. **Replace IServiceScopeFactory** with Orleans dependency injection
+2. **Update timer management** to use Orleans grain timers
+3. **Migrate state persistence** from SaveBackup/LoadBackup to Orleans state
+4. **Update bot management services** to work with grains
+
+### Phase 4: Testing & Optimization
+1. **Test backtesting compatibility** (should remain unchanged)
+2. **Performance testing** with multiple concurrent bots
+3. **High availability testing** with node failures
+4. **Memory and resource optimization**
+
+## Key Benefits
+
+1. **High Availability**: Orleans automatic failover and grain migration
+2. **Scalability**: Distributed bot execution across multiple nodes  
+3. **Performance**: Reduced serialization overhead, efficient state management
+4. **Backward Compatibility**: Backtester continues using regular classes
+5. **Simplified State Management**: Orleans handles persistence automatically
+
+## Migration Considerations
+
+1. **Async Conversion**: All bot operations become async
+2. **State Serialization**: Ensure all state classes are serializable
+3. **Timer Management**: Replace custom timers with Orleans grain timers
+4. **Dependency Injection**: Adapt from ASP.NET Core DI to Orleans DI
+5. **SignalR Integration**: Update to work with distributed grains
+
