Interpreting Zero-Window Average Money-Flow Factor Fields
Summary
The discussion clarifies how to read a BigQuant money-flow factor field whose name ends in a zero window. The question is whether “past zero trading days” means there are no observations to average, even though the description refers to an average net active buy amount. The answer interprets the zero suffix as the current trading day: with just one daily observation, its average is simply that observation’s value.
The reply also explains the adjacent window convention: a suffix of one refers to the average across the current day and the preceding trading day, or two trading days in total. This helps users understand the indexing of the rolling-window factor fields. The short exchange provides a naming interpretation rather than a definition of how active buying is calculated, how values are ranked, or how to use the factor in a model. It gives no empirical analysis or investment results.
Key ideas
- A zero suffix denotes the current trading day in the field discussed.
- The average of one daily observation equals that observation.
- A suffix of one represents a two-trading-day average under the described convention.
- The explanation clarifies field indexing but does not define the underlying active-buy calculation or validate the factor.
