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. 106 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 $5.00 12-17 call last traded $11.40 on 07/21 (now $15.50/$20.50) — try a limit near $15.50. Also watch the $25.00 12-18 call last traded $2.70 on 08/07 (now $2.50/$3.40) — try a limit near $2.70; the $30.00 12-17 call last traded $4.25 on 06/25 (now $5.00/$7.30) — try a limit near $5.00.
