A newbie asks: What is open interest?
When both buyers and sellers open new positions, open interest increases. When both sides close positions, it decreases. When one side opens a position while the other closes one, open interest stays the same.
Open interest varies greatly across different coins. Sharp short-term changes in open interest for small-cap coins are not unusual, while changes of the same magnitude in major coins are much rarer.
Rare readings often signal more volatile price swings. In such situations, it’s better to reduce your position rather than make a big bet.
