ust how important is an automated system to the Forex 
trading system?  
  Before  we answer that question, let us first determine how large Forex trading  market is. From there, we will know the importance of automated systems  for the Forex market.   
  It is true that the Forex market is the  largest market around the world not just in terms of average daily  turnover and average revenue per trader. It is also the largest market  in terms of participants.   
  You name it, we've got it. Take a look  at the following:     
BANKS- they are not just for  saving money
 and  lending capital to entrepreneurs, but they are one of the major players  in Forex market. Banks cater both to large quantity of speculative  trading and daily commercial turnover. Well-established banks can trade  billions of dollars
  worth of foreign currencies everyday. Some of the trades are undertaken  on behalf of their clients, but most are through proprietary desks.       
COMMERCIAL COMPANIES- these commercial companies trade  small quantities of foreign currencies compared to larger banks and  their trades produce small and short-term impact on the market rates.  However, the trade flows from transactions made by commercial companies  are essential factors with regards to the long-term direction of the  exchange rate of a certain currency.      
CENTRAL BANKS-  central banks play an important function in the Forex market. They have  the control over the supply of different currency, inflation, and  interest rate. In addition, they have also official target rates for the  currencies that they are handling. They are responsible for stabilizing  the Forex market through the use of foreign exchange reserves. Their  intervention in the market is enough to stabilize a certain currency.       
INVESTMENT MANAGEMENT FIRMS- these firms commonly  manage huge accounts on behalf of their clients such as endowments and  pension funds. They are using the Forex market to facilitate  transactions, specifically in foreign securities. For example, an  investment manager bearing an international equity portfolio needs to  purchase and sell several pairs of foreign currencies to pay for foreign  securities purchases.      
RETAIL FX BROKERS- they  handle a fraction of the total volume of Forex market. A single retail  forex broker
 estimates  retail volume of between  25 to 50 billion dollars each day, which is estimated to be at 2% of the  total market volume.      
SPECULATORS- these are  individuals who purchase and sell foreign currencies and profit through  fluctuations on its price as opposed to popular methods such as interest  and dividends. They perform the important role of transferring the risk  to individuals who do not wish to bear it.   
  In Forex market  alone, there are already six major players partaking on the $1.8  trillion worth of daily turnover. With a large number of Forex players,  there is really a need in switching from manual to automated Forex  trading system.   
  Among the aforementioned major Forex  players, the automated trading system is of great advantage to the  speculators. Since they focus on the price fluctuations of various  foreign currencies in order to profit, the real time data analysis will  help them determine trades that will give advantage to them.

Such complimentary system packages are  typically elementary trading system. Thus, if you are looking for more  features, you can avail of it through additional payments.   
  There  are two types of automated Forex trading system. These are discussed in  the following:  
  Desktop-based system- all Forex-related data are  stored on your desktop's hard drive. This system is unpopular to Forex  traders because all data are susceptible to computer virus contamination  and other security problems. Worse, when the computer malfunctions, all  essential information might be lost and cannot be retrieved (unless you  have some back-up files of your own). However, it is little expensive  compared to the other types of automated trading system.   
  Web-based  system- the security of your Forex account and other data are provided  by your web-based provider. These are hosted on secured servers. It is  also convenient in the sense that there will be no software required and  it is universally compatible with your Internet browser.
