Scanner

The scanner is the home screen. Each row is a direction: buy the asset on one market (the long leg) and sell or short it on another (the short leg). Rows update as quotes arrive, and the table is sorted by the net spread by default.

Parts of the page

• View switch: Table, Coins, Split or Matrix. See Views.
• Save state: All saved or Unsaved changes. Filters, columns, sort and view are saved per page with Save. See Scanner pages.
• Alert creates an alert rule from the current filters or follows this page.

• Filters opens the filter panel. The number next to it is how many filters are active. See Filters.
• Pair kinds limit the table to one kind of direction. See Pair kinds.
• Counter shows how many rows pass the filters out of all live directions.
• Live pauses and resumes updates. While paused, the counter shows how many updates are waiting.

What a row means

A row is one direction of one pair. The same two markets can appear twice, once in each direction, when both markets can be shorted. Spot cannot be shorted, so a spot leg is always the long leg, unless the exchange lets you borrow the coin on margin, which is the spot-margin and perp-margin kind. See Reading a row for every column.

​

Clicking a row

The whole row is a link. Click it to open the spread page of that direction: both legs, order books, funding, history and trading. Hover a row to see two quick actions on the left: add the pair to Favorites or hide it on this page.

When data stops

If exchanges stop answering, a banner says No fresh quotes with the time it happened. Rows are kept and marked stale. This is a data outage, not your filters, and the table comes back as soon as quotes do. If your own connection drops, the banner says Live stream lost and the page reconnects by itself. Reconnect now forces an attempt.
