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 $165.00 01-15 call last traded $9.60 on 06/10 (now $19.70/$21.90) — try a limit near $19.70. Also watch the $160.00 08-21 call last traded $10.50 on 07/17 (now $9.60/$11.30) — try a limit near $10.45. Most tradeable put: the $135.00 08-21 put last traded $5.00 on 07/13 (now $3.10/$4.00) — try a limit near $3.55.
