How to read this table
OI 24h is the change in open interest (open contracts) over the last 24 hours. On its own it only says that positions are being opened or closed. Next to price it tells you who is acting:
| Price | Open interest | Read |
|---|---|---|
| Up | Up | New money — new positions are funding the move. |
| Up | Down | Short covering — fast, often short-lived. |
| Down | Up | New shorts — sellers committing capital. |
| Down | Down | Longs exiting — unwinding rather than attacking. |
Funding adds the last piece: deeply negative funding with rising OI means shorts are crowding in and paying for it.

Frequently asked questions
What does an open interest increase mean in crypto?
More futures contracts are open than 24 hours ago — new positions are being added. Whether that is bullish or bearish depends on price: rising price with rising OI is new longs; falling price with rising OI is new shorts.
Where does this data come from?
Binance’s public futures API (open interest history in 1-hour steps), loaded directly in your browser. It covers the 120 most liquid USDT-M perpetuals.
Is a high OI gainer a buy signal?
No. It shows where positioning is changing, not where price will go. Combine it with price structure and risk management; this is not investment advice.
