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. 94 contracts (avg 598 vol/day, 94 traded recently)

CAI averages only 598 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 10-16 call last traded $10.00 on 09/17 (now $8.80/$11.60) — try a limit near $10.00. Also watch the $30.00 12-17 call last traded $8.10 on 09/15 (now $9.30/$12.50) — try a limit near $9.30; the $30.00 01-15 call last traded $2.42 on 09/01 (now $4.30/$6.00) — try a limit near $4.30.
