One market. Every venue that quotes it. Side by side.
Compare the same instrument across the venues that quote it. Every figure carries the venue, the venue's own symbol, the time it was received and its age.
Ticker, open interest and depth arrive by separate calls at separate rates, so each row carries three ages, never one. The instrument, metric and range are part of the page address, so the view can be shared as a link.

How to read this table
What is compared, and what is left out.
The rest of the rules, in full, are on the Methodology page.
Best Worst rank four columns only: a higher bid, a lower ask, a narrower spread, and more depth taken as bid plus ask. Mark, index, funding and open interest are never ranked.
Venues are ranked inside their quote-currency group, and only if the venue runs an order book and the value is LIVE. A group with fewer than two such values, or with all of them equal, shows no rank. Venues that share the best value each carry BEST ×n; hover the mark to see who with.
A hatched cell means the venue publishes no such field — an oracle-vault market has no order book. A dash means this snapshot carried no value. A dimmed figure is stale.
- Spread is compared as computed, before the two-decimal display
- Each quote group has its own BEST and WORST
- The rank slot is always reserved, so no column moves
- Sorting reorders venues inside their quote group, never across groups
- Rank and state are told by form, not colour: they read the same in greyscale
- Lines on the chart never bridge a gap
