Reliability is a feature.

A strict rule format keeps UI ↔ API ↔ engine consistent.

We validate behavior with deterministic replay before shipping.

What makes an alert deterministic?

The same inputs (candles + rule JSON) must always produce the same trigger outcome—no hidden defaults, no ambiguous rounding, no surprise evaluation timing.

How do we avoid duplicate triggers?

Alerts support trigger modes like “intrabar once” and downstream dedupe to prevent repeated notifications for the same event.

Secure authentication & account control

Optional MFA (Authenticator App)

No trading, no exchange API keys required for alerting
