# DteTide

> Net options flow of near dated contracts, bucketed to the minute and broken out by underlying type, moneyness and time to expiry. Every trade counts into four buckets: its own moneyness and ALL_MONEYNESS, crossed with its own underlying type and ALL_TYPES, so the ALL buckets are pre-aggregated roll ups. Each message is a per window partial sum; consumers add messages with the same bucket together. net means ask side minus bid side.
