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. 21 contracts (avg 87 vol/day, 20 traded recently)

AMPH averages only 87 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 $20.00 08-21 call last traded $1.25 on 07/16 (now $0.80/$1.65) — try a limit near $1.23.
