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. 88 contracts (avg 498 vol/day, 88 traded recently)

PSA averages only 498 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 $300.00 12-18 call last traded $30.50 on 07/15 (now $24.40/$27.40) — try a limit near $25.90. Also watch the $330.00 08-21 call last traded $5.90 on 07/17 (now $2.30/$3.30) — try a limit near $2.80; the $330.00 09-18 call last traded $8.90 on 07/17 (now $4.00/$6.20) — try a limit near $5.10. Most tradeable put: the $310.00 08-21 put last traded $6.50 on 07/17 (now $8.00/$10.80) — try a limit near $8.00.
