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. 89 contracts (avg 69 vol/day, 88 traded recently)

WAT averages only 69 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 $370.00 08-21 call last traded $26.40 on 07/23 (now $26.80/$32.40) — try a limit near $26.80. Also watch the $400.00 08-21 call last traded $10.20 on 07/24 (now $9.80/$16.10) — try a limit near $10.20; the $430.00 08-21 call last traded $2.75 on 07/24 (now $1.90/$7.80) — try a limit near $2.75. Most tradeable put: the $370.00 08-21 put last traded $13.50 on 07/23 (now $11.30/$15.90) — try a limit near $13.50.
