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. 87 contracts (avg 156 vol/day, 87 traded recently)

PTGX averages only 156 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 $155.00 10-16 call last traded $12.00 on 08/13 (now $7.70/$11.50) — try a limit near $9.60. Also watch the $155.00 09-18 call last traded $7.70 on 08/21 (now $3.90/$5.90) — try a limit near $4.90; the $145.00 09-18 call last traded $10.00 on 08/20 (now $7.90/$12.00) — try a limit near $9.95. Most tradeable put: the $145.00 09-18 put last traded $5.73 on 08/20 (now $2.65/$6.20) — try a limit near $4.43.
