Hello everyone, I am fairly new to day trading and I have been trying for some time to find if there is some resource out there that will give me price alerts for all stocks (at least stocks traded on Nasdaq and NYSE) that move up or down (say 10%) in a short period of time (say 15 or 30 minutes). Does anyone know of a trading platform or some other service that does this? So far all I can really find is screeners or scanners that will show you the biggest gainers and decliners for the day (such as Yahoo Stock Center or Finviz). But from what I can tell once a scan has been run, these sites will keep updating the listings on the current scan but say some other stock gaps up by 10 or 20% in the middle of the day, that stock won't be on that screen because it was run before the stock went up so much. Hope this makes sense. I would appreciate any help on the subject.
All depends what you need. If for daytrading take a look at scanners that your platforms offer. Might be enough for your needs. But basically the best way is to use rather proffesional scanners like Trade Ideas or Madscan. Both have demo version so you can check. For Trade Ideas I have 30% rebate if you would like. Midsession gap up/down is usually after halt. Halts you can check on Nasdaq official website.
