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 238 vol/day, 61 traded recently)

QDEL averages only 238 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 $0.50 on 07/31 (now $0.30/$1.40) — try a limit near $0.50. Most tradeable put: the $10.00 12-18 put last traded $0.94 on 07/02 (now $0.50/$0.95) — try a limit near $0.73.
