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 $145.00 08-21 call last traded $7.50 on 08/07 (now $5.00/$8.00) — try a limit near $6.50. Most tradeable put: the $140.00 09-18 put last traded $7.60 on 08/06 (now $2.90/$7.00) — try a limit near $4.95.
