Quantitative Trading System researches, identifies, and then isolates patterns and price or value movements in the markets which tend to constantly reoccur.

The system's algorithms search for and signal objective buy and sell short signals in real time. The signals can be used for transaction timing, asset allocation modeling, and as a decision support and analysis mechanism. Quantitative trading and analysis is a highly complex area, requiring considerable research and IT resources. As computer hardware has developed over the last ten years, powerful processors are now widely available, enabling quantitative practitioners to scrutinize a vast amount of data. In the past, classical parametric methods for analysis have been used for this purpose. However, today, the widespread availability of powerful computers coupled with the competitive drive to gain a trading advantage is motivating quantitative practitioners to explore alternative nonparametric methods. These techniques push far beyond standard linear relationships into the more complex sphere of nonlinear analysis.

Normally, to be able to trade Forex, one must spend at least 3-6 months to learn about Forex basics, reading Forex charts, using technical indicators to determine buy/sell/exit signals. Even learning so many things like that still can not guarantee profits because trading is ruthless, no one can predict the market. The only way to be profitable is to identify the trends and ride the trends to maximum. Only a few elite individual traders can do that! The fact is
95% of traders lose their money! (And the winners are always the big 'sharks' banks or financial institutes which have thousand of brightest brains working for them and many complicated trading systems that run on power of thousands of super computers).

However, there are still chances for small investors/traders if they are equipped with the right trading systems with good enter/exit strategies, stable money management methods...

Technical Forex trading is primarily based on one of two tools. Charting tools are, as the name suggests, charts of past currency movements. As with any chart, you can add in trend lines to help smooth out the minor fluctuations and
allow you to see the bigger picture. Of course, charting is a lot more complicated than mere trend lines but there are software programs out there that will help with your chart analysis. Once you get deeper into charts, the other main technical Forex trading method is the use of Quantitative Trading Models. These use math to analyze the markets and identify opportunities for trading. Technical trading uses past data to endeavor to predict future movements in the market.

Fundamental Forex trading involves the analysis of things such as key economic data. This includes reports from governments, current event news coverage and any other data that the fundamental analyst considers useful. Fundamentalists consider that currency movements are mainly affected by economic and political conditions and events. Whilst central banks have been known to get involved in the currency markets, this has become less common in recent years. Fundamentalist Forex trading looks at interest rates, inflation figures, balance of trade figures, Gross Domestic Product, retail price indexes, producer price indexes amongst other factors.

You need to decide which of these two trading styles fits best with your own personal style as well as the amount of time you have available for analysis and any help that you can get from computer programs.
