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. 125 contracts (avg 411 vol/day, 125 traded recently)

PTCT averages only 411 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 $85.00 01-15 call last traded $8.65 on 07/29 (now $4.80/$5.80) — try a limit near $5.30.
