There is a lot of hype around day trading. Some websites promote it as a way to get rich quick (it isn't), and others say it is impossible (also not true). There are lots of day traders around the world who find success and make a living off the markets, so the truth lies somewhere in between those two extremes. If you've thought about day trading, it's worth your time to read through and understand the concepts discussed below, so you'll be better prepared for what to expect if you decide to proceed.
In addition to knowledge of basic trading procedures, day traders need to keep up on the latest stock market news and events that affect stocks—the Fed's interest rate plans, the economic outlook, etc. So do your homework. Make a wish list of stocks you'd like to trade and keep yourself informed about the selected companies and general markets. Scan business news and visit reliable financial websites.
