listenSignalBacktestClosed

declare function listenSignalBacktestClosed(fn: (event: IStrategyTickResultClosed) => void): () => void;

Subscribes to closed tick results from backtest executions only.

Fires when a position closes, for any reason. closeReason says which ("take_profit", "stop_loss", "time_expired" or "closed" for a user-initiated close), closeTimestamp says when, and pnl holds the realised result with fees and slippage already applied. Terminal for that signal - no further events for it will arrive on this channel.

Receives events from Backtest.run() only. Live trading never reaches this callback, so it is the right channel for replay analysis and reporting that must not be polluted by production traffic.

Because the emitter is already split by action, the callback receives the narrowed variant directly - no if (event.action === ...) guard is needed before reading the fields described above.
