Features:

  • Wraps PersistBase for atomic JSON writes
  • Uses fixed entity ID "positions" within a per-context PersistBase
  • Crash-safe via atomic writes

Example

const instance = new PersistRiskInstance("my-risk", "binance");
await instance.waitForInit(true);
await instance.writePositionData([["strategy:BTCUSDT", positionData]]);
const positions = await instance.readPositionData();
