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. 111 contracts (avg 349 vol/day, 110 traded recently)

PTCT averages only 349 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 $90.00 01-21 call last traded $21.40 on 07/13 (now $17.30/$20.20) — try a limit near $18.75. Also watch the $110.00 01-21 call last traded $20.40 on 07/08 (now $11.30/$14.60) — try a limit near $12.95; the $95.00 09-18 call last traded $1.90 on 07/24 (now $1.35/$2.40) — try a limit near $1.88. Most tradeable put: the $85.00 01-21 put last traded $20.80 on 07/10 (now $22.00/$24.60) — try a limit near $22.00.
