If you're the type of person who doesn't want to spend a lot of time monitoring the markets, then a forex robot can be a great way to trade. You can simply set it up and let it do its thing.
Of course, there are also some downsides to using forex robots. One is that they are not 100% reliable and do have technical limitations. Another is that if the market conditions change, the robot may not be able to adapt and could start making losing trades.
