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. 95 contracts (avg 447 vol/day, 94 traded recently)

PSA averages only 447 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 $310.00 09-18 call last traded $27.00 on 06/23 (now $19.20/$22.00) — try a limit near $20.60. Also watch the $320.00 09-18 call last traded $13.70 on 07/24 (now $12.30/$15.60) — try a limit near $13.70; the $340.00 12-18 call last traded $10.50 on 07/23 (now $11.00/$14.30) — try a limit near $11.00. Most tradeable put: the $330.00 09-18 put last traded $17.40 on 07/17 (now $13.00/$15.70) — try a limit near $14.35.
