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. 123 contracts (avg 31 vol/day, 122 traded recently)

KALU averages only 31 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 $150.00 11-20 call last traded $24.24 on 07/27 (now $12.50/$17.20) — try a limit near $14.85. Also watch the $170.00 09-18 call last traded $14.82 on 08/07 (now $0.60/$4.90) — try a limit near $2.75; the $185.00 08-21 call last traded $2.97 on 08/06 (now $0.00/$1.15) — try a limit near $0.57. Most tradeable put: the $100.00 03-19 put last traded $2.60 on 07/23 (now $1.95/$5.20) — try a limit near $2.60.
