Bitcoin options expiring on November 9 showed a heavy concentration of call open interest, while puts held a slight lead in trading across expiries over the past 24 hours. The positioning showed a contrast between call-heavy outstanding contracts for November 9 and greater put activity in the broader market’s latest trading. As of November 6, total open interest for the November 9 expiry stood at 7,029 contracts, with a notional value of approximately $539.22 million. Call open interest totaled 6,503 contracts, compared with 526 puts, giving a put/call ratio of 0.08. The ratio showed that calls substantially outnumbered puts for that expiry.

They can be used to take positions on price movements or hedge existing exposure. Open interest is the total number of outstanding contracts.
