What is a stock screener?
A stock screener filters the market so you can find names that match rules — biggest percent movers, highest volume, or session activity outside the regular open. Instead of scanning thousands of tickers by hand, presets surface a short list you can research further.
Extended hours vs trade tape
Pre-market and after-hours quotes show where liquid stocks last traded outside regular hours. That is useful for spotting gaps before the open or moves after news. It is not the same as a full after-hours trade tape listing every print.
