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. 82 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 $2.50 12-18 call last traded $11.10 on 06/10 (now $11.50/$16.20) — try a limit near $11.50. Also watch the $12.50 12-18 call last traded $7.17 on 07/01 (now $4.70/$7.40) — try a limit near $6.05; the $7.50 12-18 call last traded $10.60 on 06/30 (now $7.20/$11.50) — try a limit near $9.35. Most tradeable put: the $27.50 12-18 put last traded $10.74 on 06/29 (now $10.40/$12.60) — try a limit near $10.74.
