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. 22 contracts (avg 102 vol/day, 22 traded recently)

AMPH averages only 102 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 $25.00 12-18 call last traded $1.00 on 07/16 (now $0.05/$1.80) — try a limit near $0.93. Also watch the $22.50 08-21 call last traded $0.70 on 07/20 (now $0.00/$1.50) — try a limit near $0.70. Most tradeable put: the $15.00 08-21 put last traded $0.30 on 07/06 (now $0.05/$0.75) — try a limit near $0.30.
