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. 97 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 $130.00 08-21 call last traded $13.44 on 07/27 (now $22.00/$26.50) — try a limit near $22.00. Also watch the $145.00 08-21 call last traded $7.50 on 08/07 (now $7.00/$11.40) — try a limit near $7.50. Most tradeable put: the $135.00 09-18 put last traded $6.30 on 08/06 (now $1.00/$2.20) — try a limit near $1.60.
