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. 77 contracts (avg 287 vol/day, 76 traded recently)

CAI averages only 287 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 $15.00 12-17 call last traded $7.50 on 07/13 (now $5.00/$6.70) — try a limit near $5.85. Also watch the $25.00 12-17 call last traded $4.74 on 06/01 (now $2.90/$5.30) — try a limit near $4.10; the $10.00 12-17 call last traded $9.60 on 07/13 (now $6.00/$11.00) — try a limit near $8.50. Most tradeable put: the $15.00 10-16 put last traded $1.50 on 07/06 (now $1.40/$2.55) — try a limit near $1.50.
