Interface PartialProfitContract

Contract for partial profit level events.

Emitted by partialProfitSubject when a signal reaches a profit level milestone (10%, 20%, 30%, etc). Used for tracking partial take-profit execution and monitoring strategy performance.

Events are emitted only once per level per signal (Set-based deduplication in ClientPartial). Multiple levels can be emitted in a single tick if price jumps significantly.

Consumers:

  • PartialMarkdownService: Accumulates events for report generation
  • User callbacks via listenPartialProfit() / listenPartialProfitOnce()

Example

import { listenPartialProfit } from "backtest-kit";

// Listen to all partial profit events
listenPartialProfit((event) => {
  console.log(`[${event.backtest ? "Backtest" : "Live"}] Signal ${event.data.id} reached ${event.level}% profit`);
  console.log(`Symbol: ${event.symbol}, Price: ${event.currentPrice}`);
  console.log(`Position: ${event.data.position}, Entry: ${event.data.priceOpen}`);
});

// Wait for first 50% profit level
listenPartialProfitOnce(
  (event) => event.level === 50,
  (event) => console.log("50% profit reached:", event.data.id)
);
interface PartialProfitContract {
    backtest: boolean;
    currentPrice: number;
    data: ISignalRow;
    level: PartialLevel;
    symbol: string;
    timestamp: number;
}

Properties

Properties

backtest

backtest: boolean

Execution mode flag.

  • true: Event from backtest execution (historical candle data)
  • false: Event from live trading (real-time tick)

currentPrice

currentPrice: number

Current market price at which this profit level was reached. Used to calculate actual profit percentage.

data

data: ISignalRow

Complete signal row data. Contains all signal information: id, position, priceOpen, priceTakeProfit, priceStopLoss, etc.

level

level: PartialLevel

Profit level milestone reached (10, 20, 30, 40, 50, 60, 70, 80, 90, or 100). Represents percentage profit relative to entry price.

Example

// If entry was $50000 and level is 20:
// currentPrice >= $60000 (20% profit)

symbol

symbol: string

Trading pair symbol (e.g., "BTCUSDT"). Identifies which market this profit event belongs to.

timestamp

timestamp: number

Event timestamp in milliseconds since Unix epoch.

Timing semantics:

  • Live mode: when.getTime() at the moment profit level was detected
  • Backtest mode: candle.timestamp of the candle that triggered the level

Example

const eventDate = new Date(event.timestamp);
console.log(`Profit reached at: ${eventDate.toISOString()}`);
