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. 107 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 $130.00 08-21 call last traded $13.90 on 06/18 (now $24.30/$28.10) — try a limit near $24.30. Also watch the $160.00 08-21 call last traded $10.50 on 07/17 (now $6.90/$10.30) — try a limit near $8.60. Most tradeable put: the $145.00 08-21 put last traded $8.20 on 07/15 (now $7.40/$9.40) — try a limit near $8.20.
