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 $125.00 12-17 call last traded $37.75 on 06/17 (now $53.50/$57.20) — try a limit near $53.50. Also watch the $190.00 08-21 call last traded $1.40 on 07/02 (now $0.75/$2.90) — try a limit near $1.40. Most tradeable put: the $145.00 08-21 put last traded $8.20 on 07/15 (now $7.40/$9.00) — try a limit near $8.20.
