Technical Analysis of Stocks

For an ordinary individual, trade is nothing but the exchange of goods or services within an agreed exchange rate. You purchased a pack of candy for $2, and the trade is done. You purchased a $45,000 4-door sedan, and the trade is done. You purchased a $4.5-million house, and the trade is done. The deal is closed once you got what you want out of your money, and the seller got what he wants out of a thing or property he sells to you.
However, for traders on different exchanges, trade is always a priority to consider. They have invested from hundreds to hundred thousands of dollars in the hope of generating larger profits later on. By trading different assets and securities with different traders coming from different exchanges, they are hoping that they will be able to come up with a huge profit and continue their trading careers until their bank accounts either swell or become dehydrated.
Furthermore, for different national governments, trade is always a blessing that everybody should be thankful for. The economy of different countries heavily depends on the performance of both international and local trades in the market. Successful trades often translate to a higher GDP or gross domestic product, which is one of the indicators of a prosperous national economy. Successful trades also translate to additional employment, helping jobless people to have work and earn for their respective families.
Trade is also a blessing for different stock traders (individuals who are engaged in trading stocks) and different corporations who are issuing stocks to the public to raise additional revenues. Once the market value of a company stock becomes higher, traders who hold that particular stock are guaranteed of a profit once the stocks are disposed to interested investors. On other hand, corporations that issues stocks to the public are also guaranteed to huge return of investment since the value of their common stocks in the market are now higher that it was previously released. In other words, both parties benefit from the actual trading of stocks in different exchanges.
However, it does not necessarily mean that you will automatically call it a "deal" when a corporation or a trader comes to you and offers you some stocks. Just like buying a home or any expensive assets, you need to study first the movement of the market and determine if it will be profitable to make a deal or not on that particular moment. Such extensive study is also known as technical analysis.
In finance and investment, technical analysis is the study about an asset's or security's (in this case, the security is the stock) price action (movement of the price, volume, and open interest) in the market to forecast profitable price trends and movements.
