Common comparison error
A side-by-side screenshot cannot establish quote latency because the source and platform clocks, refresh cadence, and network path may differ.
GlossaryPlatform & service
Quote latency
The delay between a source-price update and its appearance on the platform. It is material for short-expiry contract review.
Practical use
How to verify Quote latency
Read Quote latency together with Expiry countdown, Order submission latency, Partial outage. The comparison must preserve the exact rule, value, state, and evidence described below.
A neutral example
Source and broker clocks are synchronized before 200 quote updates are sampled. A median 180-millisecond source-to-platform delay is reported with tail values and the contract durations it could affect.
Evidence path
Where to verify Quote latency
Use the source that governs the exact contract, account, entity, or platform state. A general definition cannot replace current broker terms.
