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. 101 contracts (avg 148 vol/day, 96 traded recently)

WST averages only 148 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 $350.00 12-17 call last traded $79.00 on 09/25 (now $72.00/$76.00) — try a limit near $74.00. Also watch the $330.00 03-19 call last traded $46.10 on 09/02 (now $56.10/$59.60) — try a limit near $56.10; the $360.00 12-18 call last traded $28.55 on 09/21 (now $25.90/$29.20) — try a limit near $27.55. Most tradeable put: the $340.00 11-20 put last traded $11.66 on 09/21 (now $9.20/$10.90) — try a limit near $10.05.
