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 $180.00 12-18 call last traded $14.90 on 07/10 (now $10.60/$14.80) — try a limit near $12.70. Most tradeable put: the $145.00 08-21 put last traded $8.20 on 07/15 (now $6.60/$9.60) — try a limit near $8.10.
