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. 87 contracts (avg 49 vol/day, 86 traded recently)

WSO averages only 49 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 08-21 call last traded $33.90 on 05/22 (now $16.90/$21.30) — try a limit near $19.10. Most tradeable put: the $400.00 08-21 put last traded $35.45 on 07/17 (now $32.80/$38.10) — try a limit near $35.45.
