A Filter System for Selecting Trading Instruments R package filters.trade version 0.0.1 Enables filtering datasets of tradable instruments by prior specified identifiers which correspond to saved filter expressions. A filter is a named expression bound to a target dataset, stored once in a package level registry, and later applied to select trading codes such as tickers or symbols out of a universe, price or signal dataset. The design follows the `filters` package, replacing the clinical study dataset convention with a trading instrument convention.
