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 $70.00 01-21 call last traded $24.30 on 07/29 (now $20.10/$23.60) — try a limit near $21.85. Also watch the $85.00 01-15 call last traded $8.65 on 07/29 (now $4.40/$8.10) — try a limit near $6.25; the $110.00 12-18 call last traded $4.76 on 06/24 (now $0.60/$2.25) — try a limit near $1.43. Most tradeable put: the $60.00 08-21 put last traded $0.85 on 07/30 (now $0.00/$0.55) — try a limit near $0.28.
