I am wondering if the forex market is growing to extinction or growing to explosion.

Please let somebody teach me wisdom about trading with softwares.

Today, may be more than before, many traders are developing trading softwares

that can make millions of dollars for a trader in weeks. They will tell you 'goooood'

stories of how this system has been tried and proved to be the best. They will post

testimonies of those who are using them. They will tell you that it has never lost a

in these market that all us has agreed that you can never have a 100% winning

trades. Which I know is true.

And these softwares will be priced so high or low as the developer wants it.

Now my concern is this- If this systems are this 'goooood' why do that trader want

almost every other trader to own this good thing? Why is the seller not using it to

make that much money for himself instead of wanting to sell it to others and still

make thousands of dollars from the its sales? Why are there persuading others to

buy it; DO they love more my making profits or my money (buying it) which make

them to attach a bigger price to it?

Thank you in advance as you help me to understand this more better.
