What are forex robots?
Robot software works fairly simply. You set up an account (either a demo or a real-time account), plug in the same trading parameters that you'd normally use when doing forex trades, and then let the software go to work. It basically simplifies the trading process by doing the trades for you once you've established what patterns you want to use.
Hard to use?
The best forex robots have simple, user-friendly interfaces that aren't hard to learn; the hard part is coming up with a winning trade system. Even an automated currency trading system will require a lot of back and forward testing. No piece of software is a guaranteed income generator, and anything that promises that is scammy and should be avoided.
Worth it for me?
Most autopilot forex software runs between $100-200 for a one-time purchase, and may have upgradeable features. If you have managed to come up with a trading plan that's working for you and you're seeing consistent results, forex robot software can make your life a lot easier. You can even start multiple trading accounts and double or triple your profits. However, if you aren't successfully trading forex already, robot software isn't going to fix that problem. Instead, you should research the basic trading concepts essential to anyone who wants to make money using forex.
How do I pick one?
The best way to figure out what forex robot will suit your needs is to try them. All the good autopilot forex programs have demo account options that let you plug in actual trading parameters and then test the results risk-free, without any actual investing going on. Trying 2 or 3 different robots with demo accounts like this is a good way to determine if they'll work with your current setup. Most good robots come with 30-60 day moneyback guarantees, so you can test with the peace of mind that you'll be able to get your money back if they don't work for you.
