Ready-made lists: gainers, losers, volatile, funding and open interest

The screener shows the whole market and asks you to set up filters. The lists each answer one question and ask nothing: the selection is done, the table arrives from the server, and a link opens the same thing for anyone. The first three deliberately have no live updating — for real-time work each one carries the link «Open in the screener with all filters» at the bottom.

Gainers, losers, volatile

• The buttons «Gainers», «Losers», «Volatile» above the table switch between the three lists: /gainers, /losers, /volatile.
• Each holds 30 rows, crypto only, only with 24h volume of at least $1M — otherwise dead small caps with paper percentages on three trades would top the list.
• «Gainers» is sorted by «24h change» descending, «Losers» ascending, «Volatile» by «24h range».
• Columns: number, «Coin» (a link to the coin page), «Price», «24h change», «24h range», «24h volume».
• The data is the same snapshot the screener uses; the table is rebuilt every time the page opens.

The 24-hour window

The screener shows movement over four windows — 5 minutes, 15 minutes, an hour and a day; the lists use the day only. «24h change» is the price change over the last 24 hours. «24h range» is the width of the daily range: the high minus the low, relative to the low, in percent. A coin can close the day flat and still travel 15% there and back — «Volatile» will show it, «Gainers» will not.

/funding — the funding spread

• The «Funding spread» page is the first tab of the «Arbitrage» section (next to it: «Spot + futures», «Spot → spot»).
• Columns: «Ticker», one column per futures exchange, «Spread», «Volume 24h». Sort by clicking a header; the default is spread descending.
• A green cell is the coin's highest rate, red the lowest; the spread is the gap between them. An empty cell means that exchange does not trade the contract.
• «Min volume»: «All», «$1M+», «$10M+». The default is $1M+ — with turnover in the tens of thousands a spread cannot be traded.
• The «per period» / «annualized» switch — see the next section. The «Exchanges» button removes venues from the table and the spread is recomputed without them.
• The «Alerts» button — a Telegram message when a spread above your threshold holds for 3 updates in a row (about three minutes). Needs an account and a connected bot.

What funding periods are

An exchange reports the rate per payment period, and periods differ even within one exchange: Binance has 442 contracts with four-hour funding against 302 with eight-hour. The same 0.01% at a four-hour period earns twice as much as at eight hours. By default rates are shown «per period» — as in the exchange terminal; a mark like «4h» next to a cell means a non-standard period, eight-hour cells carry no mark. The «annualized» mode brings every rate to a year — the rate times 8760 divided by the period's hours — and only there are exchanges honestly comparable; highlighting and the spread are recomputed on the converted numbers. Hover a cell and the tooltip shows both numbers. If an exchange sent no period, we assume eight hours.

Basis and carry

Below the rates table sits «Basis & carry»: the return of the pair «buy spot — short the futures», where price is neutral and funding drips in. Columns: «Ticker», «Basis» (how much the futures trade above Binance spot right now), «Best venue», «Period», «Carry, annual», «Volume 24h». Basis is shown only where spot and futures agree in price within 3%: one ticker can hide different assets, and a wild basis is a naming collision, not a find. Annual means if the rate held for a year, which never happens; subtract fees on both venues and slippage from the return. We show data, we do not promise profit.

/oi — market open interest

• The «Market open interest» page is the «Open interest» tab of the «Analytics» section (next to it: «Overview», «Sentiment», «BTC cycles», «Arbitrage»). The heading shows the sum across the whole market labelled «entire market».
• Above the table is a legend of exchanges with each one's total OI; in the rows the «Venue split» bar — hover a coloured segment to see the exchange and the amount.
• Columns: «Coin», «OI» (in dollars, summed across exchanges), «Venue split», «1h chg», «Rank», «Volume 24h». Sort by clicking a header; the default is by OI.
• «Rank» is where the coin's current OI sits within its own history over the last ~20 days, from 0 to 100; it is computed in contracts rather than dollars, otherwise it would rise with price on its own.
• The table is shown in portions and the «Show … more» button loads further rows; it refreshes once a minute.
