Navigation: Realtest Script Language > Syntax Element Details > #ByListNum Category Cross-Sectional Functions Description A secondary cross-sectional function, which requests that the primary function be calculated separately for the stocks from each separate IncludeList Example ListCount: #Sum #ByListNum 1 Counts the number of stocks in the same IncludeList as the current stock. Notes The ListNum of a symbol is the number of the first IncludeList that it appears in. The above example is therefore only useful when each IncludeList contains unique symbols. The secondary cross-sectional ranking functions all work this way. For example a stock cannot belong to more than one sector or industry. Copyright © 2020-2026 Systematic Solutions, LLC
