PersistSignalInstance

Implements IPersistSignalInstance

Default file-based implementation of IPersistSignalInstance.

Features:

• Wraps PersistBase for atomic JSON writes
• Uses symbol as entity ID within a per-context PersistBase
• Crash-safe via atomic writes

Constructor

constructor(symbol: string, strategyName: string, exchangeName: string);
Copy

Properties

symbol

symbol: string
Copy

strategyName

strategyName: string
Copy

exchangeName

exchangeName: string
Copy

_storage

_storage: any
Copy

Underlying file-based storage scoped to this context

Methods

waitForInit

waitForInit(initial: boolean): Promise<void>;
Copy

Initializes the underlying PersistBase storage. Delegates to PersistBase.waitForInit which uses singleshot.

readSignalData

readSignalData(): Promise<ISignalRow | null>;
Copy

Reads the persisted signal using symbol as the entity key.

writeSignalData

writeSignalData(signalRow: ISignalRow | null): Promise<void>;
Copy

Writes the signal (or null to clear) using symbol as the entity key.
