BacktestMarkdownService

Service for generating and saving backtest markdown reports.

Features:

• Listens to signal events via onTick callback
• Accumulates closed signals per strategy using memoized storage
• Generates markdown tables with detailed signal information
• Saves reports to disk in logs/backtest/{strategyName}.md

Properties

loggerService

loggerService: any
Copy

Logger service for debug output

getStorage

getStorage: any
Copy

Memoized function to get or create ReportStorage for a symbol-strategy-exchange-frame-backtest combination. Each combination gets its own isolated storage instance.

tick

tick: any
Copy

Processes tick events and accumulates closed signals. Should be called from IStrategyCallbacks.onTick.

Only processes closed signals - opened signals are ignored.

getData

getData: (symbol: string, strategyName: string, exchangeName: string, frameName: string, backtest: boolean) => Promise<BacktestStatisticsModel>
Copy

Gets statistical data from all closed signals for a symbol-strategy pair. Delegates to ReportStorage.getData().

getReport

getReport: (symbol: string, strategyName: string, exchangeName: string, frameName: string, backtest: boolean, columns?: Columns$7[]) => Promise<string>
Copy

Generates markdown report with all closed signals for a symbol-strategy pair. Delegates to ReportStorage.generateReport().

dump

dump: (symbol: string, strategyName: string, exchangeName: string, frameName: string, backtest: boolean, path?: string, columns?: Columns$7[]) => Promise<void>
Copy

Saves symbol-strategy report to disk. Creates directory if it doesn't exist. Delegates to ReportStorage.dump().

clear

clear: (payload?: { symbol: string; strategyName: string; exchangeName: string; frameName: string; backtest: boolean; }) => Promise<void>
Copy

Clears accumulated signal data from storage. If payload is provided, clears only that specific symbol-strategy-exchange-frame-backtest combination's data. If nothing is provided, clears all data.

subscribe

subscribe: (() => () => void) & ISingleshotClearable
Copy

Subscribes to backtest signal emitter to receive tick events. Protected against multiple subscriptions. Returns an unsubscribe function to stop receiving events.

unsubscribe

unsubscribe: () => Promise<void>
Copy

Unsubscribes from backtest signal emitter to stop receiving tick events. Calls the unsubscribe function returned by subscribe(). If not subscribed, does nothing.
