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. 19 contracts (avg 289 vol/day, 19 traded recently)

BLFS averages only 289 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 $35.00 08-21 call last traded $0.13 on 07/24 (now $0.20/$0.30) — try a limit near $0.20. Also watch the $25.00 08-21 call last traded $6.50 on 07/23 (now $5.30/$9.30) — try a limit near $6.50; the $30.00 01-15 call last traded $4.83 on 07/22 (now $3.40/$7.00) — try a limit near $4.83. Most tradeable put: the $25.00 08-21 put last traded $0.20 on 07/24 (now $0.00/$0.05) — try a limit near $0.03.
