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. 115 contracts (avg 152 vol/day, 115 traded recently)

WST averages only 152 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 $370.00 10-16 call last traded $3.90 on 08/28 (now $2.40/$3.20) — try a limit near $2.80. Also watch the $340.00 09-18 call last traded $22.86 on 08/20 (now $6.20/$8.30) — try a limit near $7.25; the $350.00 10-16 call last traded $16.25 on 08/25 (now $6.90/$9.40) — try a limit near $8.15. Most tradeable put: the $340.00 09-18 put last traded $5.60 on 08/21 (now $7.00/$8.60) — try a limit near $7.00.
