Swing traders usually go with the main trend of the stock. But some traders like to go against it and trade the counter trend instead. This is known as “fading,” but it has many other names: counter-trend trading, contrarian trading, and trading the fade. During an uptrend, you could take a bearish position near the swing high because you expect the stock to retrace and go back down. During a downtrend to trade the fade, you would buy shares near the swing low if you expect the stock to rebound and go back up.
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.
