: The present invention relates to a system and method for executing a selection from a dynamically-generated electronic database. The database includes a selection parameter determination engine creating selection parameters according to statistical models for weighting desirability of financial instruments combined with entered user selection preferences. Each financial instrument is electronically associated with a dynamic electronic label indicating whether the financial instrument is restricted for selection. The selection parameters are electronically converted by a selector engine to electronic output; the selector engine electronic output can be validated based on previously determined outcome parameters associated with past outcomes for the financial instruments. A computer processor executes external selections from a real-time updating external electronic exchange database based on the electronic output of the selector engine. Selection limiters prevent execution of external selections based on electronic flags.
