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. No contracts have traded recently — lean on the 30-day mark range and start your limit near the bid.
