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 $40.00 01-15 call last traded $40.60 on 07/14 (now $29.50/$32.40) — try a limit near $30.95. Also watch the $80.00 09-18 call last traded $10.23 on 06/30 (now $0.85/$2.15) — try a limit near $1.50; the $80.00 08-21 call last traded $2.70 on 07/30 (now $0.00/$0.75) — try a limit near $0.38.
