The main reason most people fail in forex trading is because they are human and suffer from such human emotions as anger, frustration and greed. Plus, as humans we suffer from tiredness, as the forex market runs 24 hours a day, this is quite reasonable, so the idea of an automated computer trading system is quite a realistic notion.
One of the most popular automated systems is the Forex Funnel, with this you do get a 60 day money back guarantee, so if it doesn't work, send it back. This software will keep a close eye on the 24 hour market for you, if it sees a profitable trend going bad, it will sell for you. If it sees a trend start to become profitable it will buy into it for you, depending on how much money you have given it to work with. This system won't make you rich overnight, neither will you lose everything overnight, it trades in the low risk/low rewards markets. Making a small but steady profit every day.
Another automated forex trading system is called Forex Tracer. Yes, like them all, it can make small losses on your part, they all do. It will however, make you a steady but small income every month. None of these computer systems will turn you into a millionaire overnight, if they say they can, you can be sure, they are a scam. The only way they could do that is if they could tell the future, which they can not. After all, forex trading is simply gambling on the foreign exchange market.
All that these forex trading systems do is help you to cut your losses quicker, and stop you from making the mistakes that you as a human are so very likely to make. Because you are human.
