Screener

The screener shows a grid of live charts, sorted by a metric you choose. The ranking updates every few seconds over the websocket. When the market rotates, the grid rotates with it, without a page reload. The pair in the top-left corner is always the current leader of whatever race you have chosen to watch.

How the ranking works

Every category is backed by one or more metrics: precise formulas computed by the engine for every pair on every update cycle. When you pick a category and metric, the screener asks the engine for the current top-N list and subscribes to live candles for exactly those pairs. As values change, pairs swap places; when a pair drops out of the top-N, its chart is replaced by the newcomer's. The number in each card's badge is the live value of the ranking metric.

Trend

The trend engine reads candle structure on every timeframe and distills it into local (hours) and global (days) trend calls, plus alignment, divergence, momentum and cross-timeframe consensus scores. Use it to find pairs where the short-term move agrees with the larger structure, or deliberately hunt divergences, where a short-term counter-move is running against the higher-timeframe trend and may snap back.

Surge

Detects abnormal activity as it happens. The current bar's volume, range and return are projected to a full bar, so a 30-second-old candle competes fairly with completed ones, then compared against recent history. On the Volume Surge metric a value of 5× means the pair is currently trading five times its normal volume for this timeframe. The default Surge Score watches all three dimensions at once (volume, range and return), each scaled to its own "clearly surging" level, so a score of 1.0 means something is surging, whichever dimension it is. This is the category to watch when you want to be early: volume surges usually precede the price moves that later show up on the gainers board.

Volatility

Movement intensity through classic estimators: NATR, realized volatility, Parkinson, Garman-Klass, Rogers-Satchell and Yang-Zhang. They differ in what they use (close-to-close returns, high-low ranges, open/close gaps) and therefore in what they are sensitive to; the inline docs on Settings → Screener explain each. More volatility means more scalping range, and also more risk: position sizing should shrink as NATR grows.

Volume

Raw traded volume in USDT over the selected window. Liquidity first: the busiest pairs have the tightest spreads and the least slippage, which matters more for scalping than for any other style. If you are new, staying in the top of this ranking is the safest place to learn.

Trades

Order-flow: trade counts, average trade sizes, taker buy/sell flow and their growth against recent averages. AVG SIZE is a simple whale detector: when the average trade size jumps far above normal, larger players are active. Taker flow tells you which side is crossing the spread: sustained aggressive buying with rising average size is the footprint of real demand, not resting orders.

Funding Rate

Positioning pressure. Extreme rates mean a crowded side pays to hold; squeezes tend to start there. The category includes the live premium (funding's leading indicator, showing where funding is heading before it settles), the 24h average and funding momentum. A pair pumping while funding goes deeply negative is being shorted into the rally: classic squeeze fuel.

BTC Correlation

How closely a pair follows Bitcoin over the recent window. High-correlation pairs are effectively BTC with extra volatility; trade them when you have a BTC view. Low-correlation movers run on their own news: they can rally through a red market, and they need their own analysis rather than a glance at the BTC chart.

Controls

  • Interval: the timeframe both the ranking and the mini-charts use, from 1m to 1w. Rankings are timeframe-specific: the most volatile pair on 1m is rarely the most volatile on 4h. Basic accounts rank on 5m; the other timeframes come with Premium.
  • Count: how many charts to show (12/24/36/48). More charts means more live subscriptions and a slower first paint; 24 is a good default on most screens, and it is also the Basic cap.
  • Pins: pinned pairs always stay in front, in the order you pinned them, regardless of the ranking. Pinning requires a free account: pins are stored on the account, not the browser, so your working set follows you between devices. Basic keeps up to 5 pinned pairs, paid plans 12.

All of these controls live in the screener's settings panel and save instantly. Guests can see them but not change them: without an account the screener stays on its defaults (trend, 5m, 12 charts, Binance), and each locked control says so when you hover it. Anything your plan does not include is locked the same way rather than hidden, so you can always see what the option does.

Which exchange the screener ranks

Osiris tracks Binance, Bybit, OKX and Bitget. The screener's settings panel has an Exchange picker and a Coverage switch: "One exchange" ranks that venue's board alone, while "All exchanges" merges every venue into a single list with one row per coin, each scored on the venue that carries it. That matters because the four boards are genuinely different: Bybit, OKX and Bitget list hundreds of pairs Binance does not, including tokenized equities and commodities, and the same coin can be surging on one venue and flat on another.

On the free plan the screener ranks Binance. Pointing it at Bybit, OKX or Bitget comes with Premium; the combined "All exchanges" view comes with Trader. Locked options stay visible in the settings panel so you can see what they do. Nothing else is restricted: charts, the market overview and search work on every exchange on every plan, so a coin that only trades on Bybit is still fully searchable, chartable and pinnable for free. See Plans & Billing.

The market info panel

Each card has an expandable market info panel with the pair's vital signs: volumes (1h/24h), NATR (1m/5m), price delta, BTC correlation, funding colored by who pays, and the AI local/global trend calls. It is the same panel the chart page shows, so you can qualify a candidate without leaving the grid.

Practical recipes

  • Catch rotations early: Surge on 1m or 5m, glance every few minutes. When an unfamiliar name appears near the top with a strong surge value, it is worth thirty seconds of attention.
  • Trend-follow with confirmation: Trend category, look for pairs where local and global calls agree, then check taker flow in the market info panel before entering.
  • Hunt squeezes: Funding category, sort for extremes, and watch the ones where price is moving against the crowded side.
  • Stay liquid: whatever you trade, cross-check 24h volume in the info panel. Thin pairs move beautifully and fill terribly.

Common questions

What does the screener rank?

Every USDT perpetual pair on the selected exchange, re-sorted live by the metric you choose: trend, surge, volatility, volume, order flow, funding or BTC correlation. The chart in the top-left corner is always the current leader of that ranking.

Which exchanges can the screener rank?

Binance on the free plan. Premium points it at Bybit, OKX or Bitget instead, one venue at a time, and Trader merges all four exchanges into one list with a single row per coin. Charts, search and the market overview stay open on every venue on every plan.

How do I keep my pairs from rotating away?

Pin them. Pinned pairs always stay first, in the order you pinned them, regardless of the ranking. Pins live on the account: 5 on the free plan, 12 on paid plans, the same on every device.

Why do rankings differ between timeframes?

Because every ranking is computed per timeframe. The most volatile pair on the 1-minute chart is rarely the most volatile on 4 hours, so rank on the timeframe you actually trade.
