## Summary
I've successfully implemented all the requested features to add BacktestId support to the strategies/bot system:
### 1. **Added BacktestId Column to BotEntity** ✅
- **File**: `src/Managing.Infrastructure.Database/PostgreSql/Entities/BotEntity.cs:47`
- Added nullable `int? BacktestId` property with documentation
- This allows bots to reference the backtest they were created from
### 2. **Updated Bot Domain Model** ✅
- **File**: `src/Managing.Domain/Bots/Bot.cs:37`
- Added `BacktestId` property to the domain model
- Maintains consistency between entity and domain layers
### 3. **Updated TradingBotConfig and TradingBotConfigRequest** ✅
- **File**: `src/Managing.Domain/Bots/TradingBotConfig.cs:131`
- Added `[Id(24)] public int? BacktestId` with Orleans serialization attribute
- **File**: `src/Managing.Domain/Bots/TradingBotConfigRequest.cs:119`
- Added `BacktestId` property to the request model
- These changes ensure BacktestId flows through the entire bot creation pipeline
### 4. **Updated Data Mappers** ✅
- **File**: `src/Managing.Infrastructure.Database/PostgreSql/PostgreSqlMappers.cs`
- Updated `Map(Bot bot)` at line 833 to include BacktestId
- Updated `Map(BotEntity entity)` at line 799 to include BacktestId
- Ensures proper mapping between entity and domain models
### 5. **Updated LiveTradingBotGrain** ✅
- **File**: `src/Managing.Application/Bots/Grains/LiveTradingBotGrain.cs`
- Added BacktestId to bot creation at line 1078 (for saved bots)
- Added BacktestId to bot creation at line 1145 (for running bots)
- The grain now properly persists BacktestId when saving bot statistics
### 6. **Created New Endpoint for Backtest Stats** ✅
- **File**: `src/Managing.Api/Controllers/BacktestController.cs:114`
- **New Endpoint**: `GET /Backtest/{id}/stats`
- Returns only statistical information without positions, signals, or candles:
- Basic info: id, name, ticker, timeframe, tradingType, startDate, endDate
- Performance: initialBalance, finalPnl, netPnl, growthPercentage, hodlPercentage, winRate
- Risk metrics: sharpeRatio, maxDrawdown, maxDrawdownRecoveryTime
- Other: fees, score, scoreMessage, positionCount
### 7. **Created Database Migration** ✅
- **Generated Migration**: `AddBacktestIdToBots`
- The migration adds a nullable integer column `BacktestId` to the `Bots` table
- Ready to be applied with `dotnet ef database update`
### 8. **Regenerated Frontend API Client** ✅
- Ran `dotnet build` in `src/Managing.Nswag`
- The `ManagingApi.ts` file has been regenerated with:
- `backtestId` field in bot-related DTOs
- New `/Backtest/{id}/stats` endpoint
## How It Works
### Starting a Bot from a Backtest:
1. Frontend sends `StartBotRequest` with `TradingBotConfigRequest` containing `backtestId`
2. `BotController` validates and prepares the request
3. `StartBotCommandHandler` creates the bot configuration with BacktestId
4. `LiveTradingBotGrain.CreateAsync()` receives the config and saves it to state
5. When the bot is saved via `SaveBotAsync()`, BacktestId is persisted to the database
6. The Bot entity now has a reference to its originating backtest
### Retrieving Backtest Stats:
1. Frontend calls `GET /Backtest/{id}/stats` with the backtest ID
2. Backend retrieves the full backtest from the database
3. Returns only the statistical summary (without heavy data like positions/signals/candles)
4. Frontend can display backtest performance metrics when viewing a bot
## Database Schema
```sql
ALTER TABLE "Bots" ADD COLUMN "BacktestId" integer NULL;
```
All changes follow the project's architecture patterns (Controller → Application → Repository) and maintain backward compatibility through nullable BacktestId fields.
