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. 91 contracts (avg 99 vol/day, 91 traded recently)

PTGX averages only 99 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 01-15 call last traded $23.50 on 08/31 (now $17.30/$19.40) — try a limit near $18.35. Also watch the $150.00 01-15 call last traded $14.36 on 09/04 (now $10.10/$11.90) — try a limit near $11.00; the $155.00 10-16 call last traded $12.50 on 08/25 (now $1.90/$3.50) — try a limit near $2.70. Most tradeable put: the $145.00 09-18 put last traded $3.70 on 09/03 (now $0.70/$4.90) — try a limit near $2.80.
