Utility class for managing signal storage persistence.
Features:
Used by SignalLiveUtils for live mode persistence of signals.
constructor();
PersistStorageInstanceCtor: any
Constructor used to create per-mode signal storage instances. Replaceable via usePersistStorageAdapter() / useJson() / useDummy().
getStorage: any
Memoized factory creating one IPersistStorageInstance per mode (backtest/live). Key: "backtest" or "live".
readStorageData: (backtest: boolean) => Promise<StorageData>
Reads all persisted signals for the given mode. Lazily initializes the instance on first access.
writeStorageData: (signalData: StorageData, backtest: boolean) => Promise<void>
Writes signals for the given mode. Lazily initializes the instance on first access.
usePersistStorageAdapter(Ctor: TPersistStorageInstanceCtor): void;
Registers a custom IPersistStorageInstance constructor. Clears the memoization cache so subsequent calls use the new adapter.
clear(): void;
Clears the memoized instance cache. Call when process.cwd() changes between strategy iterations.
useJson(): void;
Switches to the default file-based PersistStorageInstance.
useDummy(): void;
Switches to PersistStorageDummyInstance (all operations are no-ops).
