Observability for Quote Lag When VIX Is Quiet but Single Names Aren't
Not financial advice. Verify claims independently.
From the RT/SOFT engineering journal:
Late September 2026 chatter still frames VIX ~15 as calm even as MOVE (rates vol) and single-name earnings IV tell a different story. Index calm is not socket calm.
Metrics that matter
- p50/p99 quote age by symbol
- Reconnect storms per region
- Main-thread long tasks during burst windows
- Gap between exchange timestamp and UI paint
