About the FLEX open interest
What is FLEX open interest?
Open interest (OI) is the total value of all open FLEX perpetual futures positions, in USD. Every open contract has a long and a short side, so OI counts one side only. It rises when new positions open and falls when positions close or are liquidated.
How to read OI with price
OI up, price up: new positions opening as price rises, usually fresh longs. OI up, price down: fresh shorts. OI down, price up: shorts closing (a short squeeze if fast). OI down, price down: longs exiting or being liquidated. Large OI changes in a few hours show where leverage is building or unwinding in FLEX.
Where the numbers come from
FLEX OI comes from the public APIs of Bybit and HTX and is converted to USD at the mark price, so part of an OI change can come from the price move itself. Changes compare the current value with 5-minute snapshots the server has recorded since it last started.
Is this aggregated FLEX open interest?
Yes. The headline figure and the FLEX open interest chart sum every tracked FLEX perpetual on Bybit and HTX ($32K now), so you see the whole market rather than one exchange, with history since 27 Sep. The same series is free as JSON from /api/series/oi.
