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. 105 contracts (avg 539 vol/day, 104 traded recently)

CAI averages only 539 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 $15.00 12-17 call last traded $8.50 on 08/06 (now $12.90/$13.30) — try a limit near $12.90. Also watch the $17.50 10-16 call last traded $3.66 on 08/06 (now $7.20/$7.80) — try a limit near $7.20; the $22.50 12-17 call last traded $7.44 on 08/07 (now $8.70/$10.00) — try a limit near $8.70. Most tradeable put: the $22.50 09-18 put last traded $3.00 on 08/07 (now $0.20/$1.10) — try a limit near $0.65.
