Relative Strength Index (RSI) – Used to compare gains and losses over a specific period, it will measure the speed and change of the price movements of a security. In other words, it gives an evaluation of the strength of a security’s recent price performance. Day trading tip – this index will help you identify oversold and overbought conditions in the trading of an asset, enabling you to steer clear of potential pitfalls.
The first key to successful swing trading is picking the right stocks. The best candidates are large-cap stocks, which are among the most actively traded stocks on the major exchanges. In an active market, these stocks will swing between broadly defined high and low extremes, and the swing trader will ride the wave in one direction for a couple of days or weeks only to switch to the opposite side of the trade when the stock reverses direction.
This is usually reserved for traders working for larger institutions or those who manage large amounts of money. The dealing desk provides these traders with instantaneous order executions, which are particularly important when sharp price movements occur. For example, when an acquisition is announced, day traders looking at merger arbitrage can place their orders before the rest of the market is able to take advantage of the price differential.
The bid–ask spread is two sides of the same coin. The spread can be viewed as trading bonuses or costs according to different parties and different strategies. On one hand, traders who do NOT wish to queue their order, instead paying the market price, pay the spreads (costs). On the other hand, traders who wish to queue and wait for execution receive the spreads (bonuses). Some day trading strategies attempt to capture the spread as additional, or even the only, profits for successful trades.[18]
Individual traders often manage other people's money or simply trade with their own. Few of them have access to a trading desk, but they often have strong ties to a brokerage (due to the large amounts they spend on commissions) and access to other resources. However, the limited scope of these resources prevents them from competing directly with institutional day traders. Instead, they are forced to take more risks. Individual traders typically day trade using technical analysis and swing trades—combined with some leverage—to generate adequate profits on such small price movements in highly liquid stocks.
The second type of scalping is done by purchasing a large number of shares that are sold for a gain on a very small price movement. A trader of this style will enter into positions for several thousand shares and wait for a small move, which is usually measured in cents. Such an approach requires highly liquid stock to allow for entering and exiting 3,000 to 10,000 shares easily.

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.
