its a great live market screener. It sets key presets to the correct stocks to trade. Like Kingston stock said, there's no pre or aftermarket data. But if you're looking for a strong stock to trade on the fly this is a great, free screener.

I think that FinViz is a great screener for the price of free. Of course you must still do your due diligence and check other sources for info on the tickers that come up on your FinViz screeners.

Thanks guys, very new i have been reading, reading and reading and i really need to just do something. LOL

No you don't. Just sit and learn. You'll known when you are ready
