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 09-18 call last traded $1.35 on 07/28 (now $0.90/$3.00) — try a limit near $1.35. Most tradeable put: the $17.50 09-18 put last traded $2.95 on 07/17 (now $1.40/$2.95) — try a limit near $2.17.
