The only Enterprise trading engine for NodeJS. Enterprise-grade means the whole production stack, not just a simulator: a look-ahead-proof data layer, crash-safe atomic persistence, transactional broker commits with automatic rollback, portfolio-wide risk enforcement. Support multiple ticker execution. Same code for backtest/paper/live. Contains support for cross margin / isolated margin execution in backtest/live, DCA, trailing take. Event-driven code style like react hooks.
