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 $135.00 08-21 call last traded $12.60 on 08/06 (now $18.50/$22.00) — try a limit near $18.50. Also watch the $135.00 09-18 call last traded $10.00 on 08/03 (now $19.80/$24.00) — try a limit near $19.80.
