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. 130 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 call: the $300.00 11-20 call last traded $9.90 on 07/13 (now $6.70/$9.50) — try a limit near $8.10. Most tradeable put: the $175.00 08-21 put last traded $2.59 on 07/20 (now $0.30/$3.20) — try a limit near $1.75.
