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. 51 contracts (avg 87 vol/day, 51 traded recently)

WLK averages only 87 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 10-16 call last traded $5.50 on 09/09 (now $1.70/$2.05) — try a limit near $1.88. Also watch the $80.00 12-18 call last traded $2.90 on 09/15 (now $1.90/$2.40) — try a limit near $2.15; the $75.00 01-15 call last traded $6.90 on 09/09 (now $2.70/$5.60) — try a limit near $4.15.
