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. 81 contracts (avg 148 vol/day, 80 traded recently)

SNA averages only 148 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 $420.00 12-18 call last traded $24.65 on 07/17 (now $17.60/$20.80) — try a limit near $19.20. Also watch the $430.00 12-18 call last traded $14.55 on 06/25 (now $13.90/$16.80) — try a limit near $14.55; the $430.00 08-21 call last traded $5.40 on 07/16 (now $3.60/$4.90) — try a limit near $4.25. Most tradeable put: the $400.00 12-18 put last traded $27.90 on 06/24 (now $20.20/$24.20) — try a limit near $22.20.
