com.quantfinlib.screener.StockScreener

public final class StockScreener extends Object

Professional Stock Screener: applies technical and fundamental filters to a universe, optionally ranks matches, and exports results to CSV.

Survivorship caution: the screener sees exactly the universe it is given. A universe built from today's constituents has already dropped every delisted or acquired name — the bias enters before any filter runs. For historical screens, construct the snapshot list point-in-time via membersAsOf(java.util.List<com.quantfinlib.screener.StockSnapshot>, com.quantfinlib.data.PointInTimeUniverse, long) with a PointInTimeUniverse that includes dead tickers.

  public static List<StockSnapshot> membersAsOf(List<StockSnapshot> snapshots, PointInTimeUniverse universe, long asOfTimestamp)
