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. 104 contracts (avg 341 vol/day, 104 traded recently)

PTCT averages only 341 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 $50.00 01-21 call last traded $39.86 on 07/14 (now $36.50/$39.90) — try a limit near $38.20.
