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 $7.50 12-17 call last traded $9.50 on 07/20 (now $7.50/$11.00) — try a limit near $9.25. Also watch the $17.50 12-17 call last traded $6.20 on 07/15 (now $4.90/$7.50) — try a limit near $6.20; the $20.00 08-21 call last traded $0.50 on 07/23 (now $0.20/$0.50) — try a limit near $0.35. Most tradeable put: the $15.00 08-21 put last traded $1.23 on 07/22 (now $0.00/$1.00) — try a limit near $0.50.
