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. 90 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 $70.00 09-18 call last traded $9.70 on 08/05 (now $9.00/$9.60) — try a limit near $9.30. Also watch the $75.00 01-15 call last traded $11.70 on 08/05 (now $9.80/$11.80) — try a limit near $10.80; the $80.00 10-16 call last traded $5.80 on 08/05 (now $4.00/$5.10) — try a limit near $4.55.
