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. 29 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 $1.25/$1.70) — try a limit near $1.25. Also watch the $15.00 09-18 call last traded $3.90 on 05/20 (now $3.10/$7.40) — try a limit near $3.90; the $22.50 08-21 call last traded $0.55 on 07/07 (now $0.50/$1.20) — try a limit near $0.55. Most tradeable put: the $25.00 08-21 put last traded $4.90 on 06/26 (now $3.20/$7.40) — try a limit near $4.90.
