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. 117 contracts (avg 699 vol/day, 116 traded recently)

BMRN averages only 699 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 $72.50 01-15 call last traded $2.25 on 07/24 (now $2.25/$3.30) — try a limit near $2.25. Also watch the $75.00 06-16 call last traded $7.50 on 07/24 (now $6.00/$9.20) — try a limit near $7.50; the $65.00 01-15 call last traded $4.60 on 07/24 (now $3.50/$5.90) — try a limit near $4.60. Most tradeable put: the $55.00 06-16 put last traded $8.00 on 07/20 (now $6.30/$8.80) — try a limit near $7.55.
