i bet jcl is not really interested as long he receives his money

btw: theoretical view: this CAN not work, because if it worked, more user would use it. If more users use it, they push the prices at the same time and influence the currencies. If really a LOT of people are using this it will be contraproductive to use this tool, as you'll buy when everybody buys, and sell when everybody sells, just seperated by different lags to the internet..

So my conclusion: If this tool works, it will stop working with rising sucess. If the tool does not work, it will never work

Or am i wrong somewhere (as already said: not that this is really important to jcl, as this is probably contract work, and not work, paid depending on how sucessful the tool is).

I doubt very much this will be the case. I can't imagine someone's offering JCL a contract in which he only gets rich if the contractor does.
Though now, this suddenly reminds me of the other project recently undertaken and thinking maybe he did sign a contract with this being offered.

Well, software like this certainly raises questions like "Can automated trading work" or "Are average users too dumb to write a trading script". Obviously, these questions can only be answered empirically and not from a gut feeling or kitchen logic. You have to try it, or look what other people do, or do studies.

All this has been done, so the short answers are Yes and No. The long answers will be given in the Dagobert documentation, which is still rudimentary but will be complete for the beta test. BTW, this is a contract project and payment is not dependent on the number of users.
