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. 104 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 $20.00 12-17 call last traded $8.00 on 08/07 (now $8.80/$11.90) — try a limit near $8.80. Also watch the $25.00 01-15 call last traded $3.20 on 08/07 (now $2.75/$4.30) — try a limit near $3.20; the $25.00 10-16 call last traded $1.70 on 08/07 (now $1.70/$3.50) — try a limit near $1.70. Most tradeable put: the $25.00 10-16 put last traded $7.50 on 06/26 (now $2.20/$4.90) — try a limit near $3.55.
