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. 7 contracts (avg 2 vol/day, 7 traded recently)

CTKB averages only 2 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 $5.00 08-21 call last traded $0.30 on 08/05 (now $0.00/$0.70) — try a limit near $0.30.
