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. 109 contracts (avg 314 vol/day, 109 traded recently)

PTCT averages only 314 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 $35.00 01-21 call last traded $40.00 on 05/22 (now $49.50/$53.00) — try a limit near $49.50. Also watch the $70.00 01-21 call last traded $31.50 on 07/10 (now $28.20/$32.50) — try a limit near $30.35; the $90.00 01-21 call last traded $28.00 on 07/08 (now $19.50/$22.90) — try a limit near $21.20. Most tradeable put: the $95.00 01-21 put last traded $26.80 on 07/10 (now $25.20/$30.00) — try a limit near $26.80.
