Automated trading systems are sometimes called algorithmic trading strategies, and are designed to be coded to make trades automatically. This comes with many benefits, such as the ability to make trades and generate profits 24 hours a day. It also allows a trader to carry out buy and sell orders much faster than what would be possible with manual trading. Another benefit of automated trading strategies is that they can be backtested over long periods of time, across many different trading pairs. This gives a good indication of just how robust a certain system is, and whether it is likely to continue to perform well in the future. On the Internet, automated or algorithmic strategies are usually referred to as Forex Robots or Expert Advisors.
