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. 131 contracts (avg 322 vol/day, 130 traded recently)

CRL averages only 322 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 put: the $230.00 08-21 put last traded $23.40 on 07/21 (now $12.00/$14.00) — try a limit near $13.00.
