PartialConnectionService

Implements IPartial

Connection service for partial profit/loss tracking.

Provides memoized ClientPartial instances per signal ID. Acts as factory and lifetime manager for ClientPartial objects.

Features:

• Creates one ClientPartial instance per signal ID (memoized)
• Configures instances with logger and event emitter callbacks
• Delegates profit/loss/clear operations to appropriate ClientPartial
• Cleans up memoized instances when signals are cleared

Architecture:

• Injected into ClientStrategy via PartialGlobalService
• Uses memoize from functools-kit for instance caching
• Emits events to partialProfitSubject/partialLossSubject

Properties

loggerService

loggerService: any
Copy

Logger service injected from DI container.

getPartial

getPartial: any
Copy

Memoized factory function for ClientPartial instances.

Creates one ClientPartial per signal ID with configured callbacks. Instances are cached until clear() is called.

Key format: signalId Value: ClientPartial instance with logger and event emitters

profit

profit: (symbol: string, data: ISignalRow, currentPrice: number, revenuePercent: number, backtest: boolean, when: Date) => Promise<void>
Copy

Processes profit state and emits events for newly reached profit levels.

Retrieves or creates ClientPartial for signal ID, initializes it if needed, then delegates to ClientPartial.profit() method.

loss

loss: (symbol: string, data: ISignalRow, currentPrice: number, lossPercent: number, backtest: boolean, when: Date) => Promise<void>
Copy

Processes loss state and emits events for newly reached loss levels.

Retrieves or creates ClientPartial for signal ID, initializes it if needed, then delegates to ClientPartial.loss() method.

clear

clear: (symbol: string, data: ISignalRow, priceClose: number) => Promise<void>
Copy

Clears partial profit/loss state when signal closes.

Retrieves ClientPartial for signal ID, initializes if needed, delegates clear operation, then removes memoized instance.

Sequence:

1. Get ClientPartial from memoize cache
2. Ensure initialization (waitForInit)
3. Call ClientPartial.clear() - removes state, persists to disk
4. Clear memoized instance - prevents memory leaks
