Everything you need to know about the free stock scanners on TheDesperateTrader.
- What is a stock scanner?
- A stock scanner continuously watches the whole market and surfaces the stocks that match a condition — trading on unusual volume, halting, gapping, hitting an RSI extreme, or leading the day's movers — so you do not have to check symbols one by one. A good scanner is real-time (no 15-minute delay) and filters out illiquid names.
- Are these stock scanners really free?
- Yes. Every scanner here is free to access, live across 11,000+ U.S. stocks with no 15-minute delay and no credit card required at signup. New accounts also start with 5 free premium days for the full real-time alerts dashboard.
- Which scanner should a day trader start with?
- Most day traders start with the RVOL (relative volume) scanner to find what is unusually active, then use the halt scanner and gap scanner for the sharpest setups. Swing traders lean on the oversold, overbought and 52-week pages. The custom screener lets you build any combination and save it.
- What is the difference between a scanner and a screener?
- A scanner runs continuously and pushes you results as conditions trigger in real time (ideal intraday). A screener runs on demand against filters you choose (price, volume, RVOL, % move) and is ideal for building a specific watchlist. This site has both, and the screener can alert you when a new stock matches a saved scan.
