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 $15.00 08-21 call last traded $1.77 on 07/21 (now $1.40/$2.05) — try a limit near $1.73. Also watch the $22.50 12-18 call last traded $1.58 on 07/23 (now $0.80/$1.70) — try a limit near $1.25; the $17.50 08-21 call last traded $0.99 on 07/20 (now $0.50/$1.75) — try a limit near $0.99. Most tradeable put: the $20.00 08-21 put last traded $3.73 on 07/16 (now $2.90/$5.00) — try a limit near $3.73.
