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. 61 contracts (avg 260 vol/day, 61 traded recently)

QDEL averages only 260 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 $40.00 12-18 call last traded $0.65 on 06/30 (now $0.30/$1.95) — try a limit near $0.65. Also watch the $42.50 12-18 call last traded $0.55 on 06/30 (now $0.20/$1.95) — try a limit near $0.55; the $45.00 12-18 call last traded $0.45 on 06/30 (now $0.05/$1.15) — try a limit near $0.45. Most tradeable put: the $12.50 09-18 put last traded $0.98 on 06/30 (now $0.30/$1.00) — try a limit near $0.65.
