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. 88 contracts (avg 294 vol/day, 88 traded recently)

CAI averages only 294 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 08-21 call last traded $5.60 on 07/22 (now $4.70/$7.30) — try a limit near $5.60. Also watch the $20.00 01-15 call last traded $4.20 on 07/02 (now $1.55/$2.50) — try a limit near $2.03.
