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. 43 contracts (avg 80 vol/day, 34 traded recently)

AMPH averages only 80 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 $5.00 07-17 call last traded $14.90 on 06/17 (now $12.90/$17.00) — try a limit near $14.90. Also watch the $20.00 08-21 call last traded $2.40 on 06/26 (now $1.10/$1.65) — try a limit near $1.38; the $15.00 09-18 call last traded $3.90 on 05/20 (now $3.30/$7.40) — try a limit near $3.90. Most tradeable put: the $25.00 08-21 put last traded $4.90 on 06/26 (now $3.20/$7.20) — try a limit near $4.90.
