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 $7.50 12-17 call last traded $12.50 on 08/06 (now $13.00/$16.60) — try a limit near $13.00. Also watch the $25.00 10-16 call last traded $1.70 on 08/07 (now $0.75/$1.65) — try a limit near $1.20; the $17.50 08-21 call last traded $4.26 on 08/07 (now $2.60/$5.80) — try a limit near $4.20. Most tradeable put: the $20.00 09-18 put last traded $1.77 on 08/07 (now $0.60/$1.00) — try a limit near $0.80.
