Open Interest

Open interest is the total number of outstanding futures contracts. Rising OI on a move means new money is driving it; falling OI means positions are closing. OI expansion during a dump often marks aggressive shorts piling in, one of the strongest continuation signals in crypto derivatives.

FAQ

What is open interest in crypto futures?

Open interest (OI) is the total value of all outstanding perpetual futures contracts on a market. Unlike volume, OI only grows when NEW positions open. It measures money committed, not turnover.

Why does open interest history matter?

OI changes reveal whether a move is driven by new positioning or by position closing. Public APIs only serve ~30 days of OI history; our archive is continuous and grows daily.
