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. 106 contracts (avg 651 vol/day, 103 traded recently)

CAI averages only 651 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 $10.00 09-18 call last traded $11.53 on 08/14 (now $18.70/$22.10) — try a limit near $18.70. Also watch the $15.00 10-16 call last traded $10.50 on 08/21 (now $13.50/$17.10) — try a limit near $13.50; the $35.00 12-17 call last traded $5.08 on 09/03 (now $7.10/$9.50) — try a limit near $7.10. Most tradeable put: the $25.00 01-15 put last traded $3.70 on 08/21 (now $1.40/$2.90) — try a limit near $2.15.
