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. 86 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 $400.00 08-21 call last traded $14.15 on 07/16 (now $7.20/$9.90) — try a limit near $8.55. Also watch the $470.00 02-19 call last traded $17.11 on 07/13 (now $8.20/$15.20) — try a limit near $11.70.
