RecentBacktestAdapter

Implements IRecentUtils

Backtest recent signal adapter with pluggable storage backend.

Features:

• Adapter pattern for swappable storage implementations
• Default adapter: RecentMemoryBacktestUtils (in-memory storage)
• Alternative adapter: RecentPersistBacktestUtils
• Convenience methods: usePersist(), useMemory()

Properties

_recentBacktestUtils

_recentBacktestUtils: any
Copy

Internal storage utils instance

handleActivePing

handleActivePing: (event: ActivePingContract) => Promise<void>
Copy

Handles active ping event. Proxies call to the underlying storage adapter.

getLatestSignal

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

Retrieves the latest signal for the given context. Proxies call to the underlying storage adapter.

getMinutesSinceLatestSignalCreated

getMinutesSinceLatestSignalCreated: (timestamp: number, symbol: string, strategyName: string, exchangeName: string, frameName: string, backtest: boolean) => Promise<number>
Copy

Returns the number of whole minutes elapsed since the latest signal's creation timestamp. Proxies call to the underlying storage adapter.

useRecentAdapter

useRecentAdapter: (Ctor: TRecentUtilsCtor) => void
Copy

Sets the storage adapter constructor. All future storage operations will use this adapter.

usePersist

usePersist: () => void
Copy

Switches to persistent storage adapter. Signals will be persisted to disk.

useMemory

useMemory: () => void
Copy

Switches to in-memory storage adapter (default). Signals will be stored in memory only.

clear

clear: () => void
Copy

Clears the cached utils instance by resetting to the default in-memory adapter.
