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. 123 contracts (avg 350 vol/day, 123 traded recently)

CRL averages only 350 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 $220.00 08-21 put last traded $13.80 on 07/17 (now $13.70/$17.30) — try a limit near $13.80.
