Data Methodology

Last updated: August 9, 2026

Every figure on Coinfuty is produced by one pipeline: collect raw derivatives data from major futures exchanges, verify it, aggregate it under the rules below, and serve it to these pages. This page explains those rules so you know exactly what each number represents — and where its limits are.

Coverage

Coinfuty tracks perpetual and dated futures markets on more than a dozen major derivatives exchanges — including Binance, OKX, Bybit, Bitget, Gate.io, HTX and Hyperliquid — covering hundreds of actively traded coins. For each coin we follow both stablecoin-margined and coin-margined contracts, and roll them into a single aggregated view per metric: open interest, funding rate, long/short ratio, liquidations and trading volume. Price is tracked at the coin level.

Collection and refresh cadence

• Headline market data (price, open interest, funding, volume) is polled roughly every 10 seconds around the clock.
• Pages are server-rendered and revalidate about every two minutes, so the HTML you receive — and the HTML search engines and AI crawlers receive — already contains current values.
• Historical series are stored per timeframe as they are observed, and an automated gap scanner continuously detects and backfills missing intervals.
• All timestamps are recorded and displayed in UTC.

Aggregation rules

Cross-exchange aggregates follow a fixed set of rules, applied identically to every coin:

• Zero and broken values are excluded. An exchange reporting zero or clearly erroneous data for a metric is dropped from that aggregate rather than silently dragging it down.
• Funding averages are open-interest-weighted. A market-wide funding figure weights each exchange by its open interest, so a small venue with an extreme rate cannot distort the average. Accumulated funding windows use the same weighting.
• Funding rates are normalized per interval. Exchanges pay funding on different schedules; where rates are compared or annualized (APR view), the payment interval is taken into account.
• Aggregated open interest sums all venues.A coin's headline OI is the sum across every covered exchange and both margin types — no single exchange sees the whole market.
• Duplicate listings are merged. When the same underlying asset trades under equivalent tickers, its markets are combined into one canonical coin so the aggregate is not split or double-counted.

Verification

Aggregates are cross-checked across exchanges and timeframes before they ship, and automated sanity guards flag values that move outside plausible bounds — for example an open interest figure inconsistent with its own recent history. Flagged data is corrected or withheld rather than displayed.

Known limitations

• Exchanges self-report their data. Delayed, revised or erroneous exchange feeds can propagate to dashboards until guards catch them.
• Aggregated figures legitimately differ from numbers published elsewhere, because methodology differs: which venues are included, how averages are weighted, and how windows are cut all change the result.
• Long/short ratios describe the population of accounts or positions on each exchange as that exchange defines them — definitions vary by venue.
• Very recent candles on historical charts may still be forming and are finalized once the interval closes.

Changes to this methodology

The pipeline evolves — new exchanges are added, guards are tightened, and aggregation rules are refined. Material changes are reflected on this page.
