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 $115.00 01-15 call last traded $34.90 on 07/07 (now $39.00/$42.50) — try a limit near $39.00. Also watch the $145.00 09-18 call last traded $9.70 on 08/06 (now $8.50/$12.80) — try a limit near $9.70; the $170.00 09-18 call last traded $3.20 on 08/06 (now $0.50/$4.90) — try a limit near $2.70.
