- LIVE
- Updating as the session runs. A price feed is called live only when the provider streams; a delayed feed never is.
- DELAYED
- The feed advances, behind the market: 15 minutes for equities, 10 for futures.
- STALE
- The feed stopped advancing. The last value stays on screen, marked, never passed off as current.
- OBSERVED
- Taken from the feed as it arrived.
- CALCULATED
- Computed by NYVERA’s engine from observed inputs, with its method recorded.
- ESTIMATE
- Modelled where no observation exists, and drawn hatched so it cannot pass for a measurement.
- HISTORICAL
- A frequency over comparable past cases, always shown with its count.
- FROZEN
- Fixed at the last settled close. The next-session model does not move during the day.
- UNCALIBRATED
- A score that has not yet earned a validated hit rate, and says so.
- UNAVAILABLE
- The system cannot run, and says why, instead of drawing nothing.
Reach levels are frequencies, shown with their counts. Nothing in NYVERA is a target, a signal or a forecast.
