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. 105 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 $70.00 01-21 call last traded $29.15 on 07/13 (now $25.90/$29.10) — try a limit near $27.50. Also watch the $85.00 09-18 call last traded $5.30 on 07/15 (now $3.40/$5.50) — try a limit near $4.45.
