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 $17.50 03-19 call last traded $3.68 on 07/30 (now $7.10/$8.70) — try a limit near $7.10. Also watch the $35.00 01-15 call last traded $0.85 on 08/06 (now $0.80/$1.20) — try a limit near $0.85; the $35.00 03-19 call last traded $1.34 on 08/06 (now $1.45/$2.20) — try a limit near $1.45. Most tradeable put: the $17.50 12-18 put last traded $4.35 on 07/23 (now $1.00/$3.10) — try a limit near $2.05.
