FAQ
What is Arbitrum open interest?
The total value of ARB perpetual futures positions that are still open. Every contract has a long and a short side, so open interest counts each pair once. It grows when new positions open and falls when positions close or are liquidated.
What does a drop in open interest mean?
Positions were closed or liquidated. If price fell at the same time, longs were most likely exiting or being liquidated (see live liquidations); if price rose, shorts were most likely covering.
Is rising open interest bullish?
Not by itself. More open interest means more leverage, which can push a move further or unwind sharply. We have not tested it as a signal yet.
