Abstract: A system for automated manipulation resistant indexing is disclosed. The system may be configured to calculate a total prefilter trade volume of an historical trade data set based on a lookback coefficient, wherein the historical trade data set associated with a prefiltered exchange set, calculate a composition percentage of the total prefilter volume for each element of the prefiltered exchange set, apply a first filtering function based on the composition percentage to the prefiltered exchange set to generate a first filtered exchange set, normalize the first filtered exchange set based on the total prefilter trade volume to generate a first normalized exchange set, and generate a first weighting function based on the first normalized exchange set.
