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 $50.00 01-15 call last traded $26.00 on 06/05 (now $27.00/$30.30) — try a limit near $27.00. Also watch the $70.00 01-21 call last traded $29.00 on 07/20 (now $23.50/$27.10) — try a limit near $25.30; the $65.00 01-21 call last traded $29.90 on 07/20 (now $26.00/$30.20) — try a limit near $28.10.
