Crypto Open Interest Change Screener
Tracked perpetuals across the exchanges in the filters below with at least $1M open interest, ranked by how much its open interest rose or fell over the last 1, 4 or 24 hours or 7 days, next to the price move over the same window. Each move gets a build-up label: new longs, new shorts, short covering or long unwinding.
The 7d open interest change needs 7 days of hourly history; the server has been collecting for 45 days, so this screener fills in automatically once that much is recorded.

How to read it. Each row is one perpetual market with at least $1M open interest; for 7 days each coin shows only its most liquid perp (the highest 24h volume, as on gainers & losers). OI 7d is the change in USD open interest over 7 days, OI change $ the same in dollars. Build-up labels use contract-equivalent OI (the USD change with the price move removed), so a rally alone doesn't read as new longs; moves under 0.5% OI or 0.1% price get no label.
Stale open interest is excluded from rankings and counts. Stale funding and volume show “—”. 7-day changes compare each market's latest recorded hour with the hour nearest 7 days earlier, from hourly history this site records itself (refreshed every 10 minutes), and show "—" until a market has 7 days of it; recorded history covers 45 days. For open interest summed per coin see open interest by coin.
Open interest screener FAQ
What is an open interest screener?
Open interest (OI) is the total value of open perpetual futures positions. This screener ranks every tracked perp on the supported exchanges shown in the filters, with at least $1M of OI, by its change over the last 1, 4 or 24 hours (or 7 days for each coin's most liquid perp), so you can spot where positions are piling in or being closed before it shows up in price. Switch the window or exchange with the buttons above the tables.
How do you read open interest together with price?
OI up, price up: new longs are opening. OI up, price down: new shorts are opening. OI down, price up: shorts are covering. OI down, price down: longs are closing or being liquidated. The labels here use contract-equivalent OI, i.e. the USD OI change with the price move removed, because USD open interest rises with price even when nobody opens a position. Moves under 0.5% in OI or 0.1% in price get no label.
Why do some changes show "—"?
Changes come from 5-minute snapshots this site records itself, so a market shows "—" for a window it does not have that much history for yet, such as a new listing. A market also needs a price change for the same window before it gets a build-up label.
Is rising open interest bullish?
Not on its own. Rising OI only says more positions are open; whether longs or shorts are the aggressors shows in the price move and in funding rates. Crowded positions with extreme funding can unwind sharply. Nothing here is financial advice.
