The problem with most of the sold systems is simple - they are designed by vendors who have never made money trading and the claims made for most are so extreme they can't be true.

Most claim you can make 100 - 1,000% per annum with little or no downside volatility and anyone who has traded knows this is not true. Most also claim to have a hit winning percentage rate of 90% or over and this is just ridiculous, even the worlds top traders can't match this. These systems are bent to fit past data and never perform in the same manner going forward, because data doesn't repeat in the same way again.

The gullible public though believes the hype from vendors can detect price changes in advance and that technology is the way to beat the market but this is not true and the marketing copy and they buy a system that doesnt work. The difference between these sold systems and free ones is - there are free ones that make money sure they don't offer gains with miniscule drawdown but they do make gains long term if you are patient and ride out short term volatility.

Also people assume because a system is free it can't beat a paid one but this is simply not true. A Simple system can make a lot of money long term if its based on sound logic. A good free system is the 4 Week Rule.

The 4 Week rule is a one rule system which is simply based upon - buying a price break of a 4 week high in a currency and then waiting until a 4 week low is hit and reversing the position. Of course this sounds incredibly simple and it is but it makes money over the longer term and has been doing so for nearly 30 years. There is another free system you can use "the Turtle Trading Rules" which are world famous they made millions in real time profits and while this system is over 20 years old it still makes big gains. This system is free and well worth checking out.

The public want instant gratification and believe the vast number of trading systems sold online feed which offer huge gains and low drawdown The gullible public buy these systems and lose money.

Most of the sold systems don't make money and there are plenty of free systems which do. The examples I have given above, are just 2 such systems but there are many more, there free and they will help you enjoy currency trading success.
