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. 91 contracts (avg 51 vol/day, 89 traded recently)

WLK averages only 51 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 $75.00 01-15 call last traded $11.70 on 08/05 (now $10.10/$11.30) — try a limit near $10.70. Also watch the $75.00 12-18 call last traded $11.50 on 07/22 (now $8.40/$11.70) — try a limit near $10.05; the $95.00 12-18 call last traded $4.02 on 08/07 (now $1.45/$4.00) — try a limit near $2.73.
