When are ratings published and how often updated?

Ratings are published ahead of each day's racing and refresh through the day as odds and conditions change.

The ratings are built and published ahead of each day's racing, then keep refreshing through the day so the numbers and prices you're looking at stay current right up to the off.

When the next day's ratings appear

The ratings for the following day are typically published in the early afternoon, usually around 1pm the day before racing, once the race cards (declarations) are out. That's why you can plan ahead the night before: as soon as a day's racing is published, the full ratings are there to study, and you can enter the free NAP Competition straight away. See How to enter the day before racing for exactly how to load tomorrow's card.

How often they update through the day

Once published, the ratings don't sit still:

• Live Win Odds and Place Odds refresh continuously from the exchanges, so the prices move as the market moves.
• Results and after-race figures (such as ISP and the in-running price reduction columns) import automatically once each race is run.
• Declarations and non-runners are reflected as the cards firm up, so the field you see stays accurate.

Professional members get early ratings on feature races at the entry stage as well as at declaration, see What's included in a Professional account?.

If the ratings look out of date

A page that seems stuck on yesterday's data is usually a browser cache issue rather than a publishing delay, a hard refresh fixes it. See The ratings won't load or display correctly. For what each refreshing column actually means, see the ratings columns reference.
