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. 113 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 $50.00 01-15 call last traded $26.00 on 06/05 (now $20.50/$23.00) — try a limit near $21.75. Also watch the $50.00 01-21 call last traded $38.22 on 07/21 (now $27.50/$31.00) — try a limit near $29.25; the $70.00 01-15 call last traded $17.00 on 07/24 (now $9.30/$10.90) — try a limit near $10.10. Most tradeable put: the $70.00 01-15 put last traded $7.60 on 07/14 (now $9.80/$11.30) — try a limit near $9.80.
