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. 121 contracts (avg 104 vol/day, 121 traded recently)

WST averages only 104 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 $290.00 12-17 call last traded $101.75 on 08/13 (now $88.50/$92.00) — try a limit near $90.25. Also watch the $360.00 10-16 call last traded $5.65 on 09/04 (now $3.40/$4.80) — try a limit near $4.10; the $340.00 09-18 call last traded $6.70 on 09/04 (now $3.90/$6.70) — try a limit near $5.30. Most tradeable put: the $340.00 09-18 put last traded $7.25 on 09/03 (now $5.40/$7.60) — try a limit near $6.50.
