The prices of these products range from free to many thousands of dollars. some are monthly fees and some are one time fees.
The reviews are based on real money tests and not paper trading though I always recommend people paper trade anything first, it does not mean the system will work with real money.
These are my reviews are my opinions and other peoples experiences may differ from mine
the cash cow signal service copies the signal that they do on their trading platform and is supposed to copy the trades onto your meta trader 4. I never had a winning trade and it cost me $75.00 us a month
it was so bad I will not even give you the link to the site
Always try it out paper trading before using real cash..
you can get a free Virtual Private Servers (VPS) from FXCM to run it on so you computer does not have to be running
