Utility class for managing risk active positions persistence.
Features:
Used by ClientRisk for live mode persistence of active positions.
constructor();
PersistRiskInstanceCtor: any
Constructor used to create per-context risk instances. Replaceable via usePersistRiskAdapter() / useJson() / useDummy().
getRiskStorage: any
Memoized factory creating one IPersistRiskInstance per (riskName, exchange) pair.
readPositionData: (riskName: string, exchangeName: string, when: Date) => Promise<RiskData>
Reads persisted active positions for the given risk context. Lazily initializes the instance on first access.
writePositionData: (riskRow: RiskData, riskName: string, exchangeName: string, when: Date) => Promise<void>
Writes active positions for the given risk context. Lazily initializes the instance on first access.
usePersistRiskAdapter(Ctor: TPersistRiskInstanceCtor): void;
Registers a custom IPersistRiskInstance 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 PersistRiskInstance.
useDummy(): void;
Switches to PersistRiskDummyInstance (all operations are no-ops).
