Historical option prices for this thinly-traded ticker. Live quotes are wide and stale — use where each contract actually traded plus its 30-day range to place a limit order. 36 contracts (avg 57 vol/day, 36 traded recently)

CLB averages only 57 option contracts/day, so quotes are thin and bid/ask spreads run wide. Use the last actually-traded price below to set a limit order rather than chasing the displayed ask. Most tradeable call: the $12.50 09-18 call last traded $0.65 on 07/17 (now $0.50/$0.80) — try a limit near $0.65. Also watch the $12.50 08-21 call last traded $0.40 on 07/15 (now $0.35/$0.65) — try a limit near $0.40; the $22.50 12-18 call last traded $0.18 on 07/08 (now $0.05/$0.20) — try a limit near $0.13.
