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. 117 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 $330.00 12-17 call last traded $78.30 on 08/17 (now $69.70/$73.00) — try a limit near $71.35. Also watch the $380.00 10-16 call last traded $2.30 on 08/28 (now $1.40/$2.40) — try a limit near $1.90. Most tradeable put: the $330.00 03-19 put last traded $26.00 on 07/17 (now $26.80/$29.50) — try a limit near $26.80.
