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.
