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. 106 contracts (avg 173 vol/day, 106 traded recently)

GKOS averages only 173 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 $175.00 08-21 call last traded $6.24 on 07/09 (now $3.10/$5.60) — try a limit near $4.35.
