IBreakeven

Breakeven tracking interface. Implemented by ClientBreakeven and BreakevenConnectionService.

Tracks when a signal's stop-loss is moved to breakeven (entry price). Emits events when threshold is reached (price moves far enough to cover transaction costs).

Methods

check

check: (symbol: string, data: IPublicSignalRow, currentPrice: number, backtest: boolean, when: Date) => Promise<boolean>
Copy

Checks if breakeven should be triggered and emits event if conditions met.

Called by ClientStrategy during signal monitoring. Checks if:

1. Breakeven not already reached
2. Price has moved far enough to cover transaction costs
3. Stop-loss can be moved to entry price

If all conditions met:

• Marks breakeven as reached
• Calls onBreakeven callback (emits to breakevenSubject)
• Persists state to disk

clear

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

Clears breakeven state when signal closes.

Called by ClientStrategy when signal completes (TP/SL/time_expired). Removes signal state from memory and persists changes to disk. Cleans up memoized ClientBreakeven instance in BreakevenConnectionService.
