For all the NYSE day traders on ET, just want to share some of the ways to determine what stocks to trade intraday before the market opens. I understand good traders can make money on almost any stocks, but experienced traders should have a system in building a universe of stock even for day trading. Let me write down some of the methods I use, and I hope in return someone can share theirs. 1.) Briefing.com (platinum), looking for earnings, upgrades/downgrades, "story stocks". I like to trade stocks with recent earning releases (2 days). One interesting aspect I found is upgraded stock can go down and downgraded stock can go up, which I think does not surprise any experienced trader. 2.) Earnings.com, a summary of events including split, dividends, conference...etc 3.) Stocks on the activity list on ECNs 4.) NYSE official web-site, I can see 30 top active, advance, and decline stocks which is better than e-signal as it has only top 10. 5.) Bloomberg.com 6.) Trade-idea, a technical screener And how do you guys prepare your day before the market open or after the close everyday?? I know some people likes to watch Cramer at night to get some trade idea, but I do not. thanks for all your opinions.
