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. 98 contracts (avg 152 vol/day, 97 traded recently)

PTGX averages only 152 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 $125.00 01-15 call last traded $22.40 on 07/29 (now $38.50/$41.00) — try a limit near $38.50.
