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. 140 contracts (avg 196 vol/day, 138 traded recently)

PEN averages only 196 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 $320.00 12-18 call last traded $10.00 on 07/28 (now $0.00/$10.60) — try a limit near $5.30. Most tradeable put: the $300.00 01-15 put last traded $113.60 on 07/29 (now $88.00/$100.10) — try a limit near $94.05.
