I don't see why that's significant to what's being discussed here, so it's not a surprise to me that nobody asked that.
For what purpose? I don't see why I would want to share any more details...
I already explained in great detail to this programmer / aspiring trader what he can expect and have given him some details and a few demonstrations of how it all works. I've explained to him that at worst he will have very detailed statistics and a new framework for analyzing/understanding how the market works.
The benefit for me is that potentially we can create something even better together as opposed to simply hiring a programmer to do work for me without any deeper knowledge of what he's doing.
In addition to giving away my secret sauce I'm a bit concerned he'll simply leave me in the dust as soon as he gets what he needs, though. I will definitely draft up a contract before beginning, but even then I'm worried there'll be issues and that one day he may decide to not pick up the phone or stop responding...
I guess I see a huge disconnect in what you're saying. On the one hand, you're saying that its not important what type of results your system is capable of generating, but on the other hand, you're scared to give away the secret sauce.
If the data that the system spits out truly is like a secret sauce, then anyone should be able to use that data and start generating amazing returns right away. In this case, I would of course be cautious, and your profit factor from the trades generated would be very high. But if the data simply generated detailed stats and a framework, that itself has to be analyzed and trade decisions have to be made, which itself would need a set of rules, then I don't see how the stats generation is a secret sauce. In this case, I would hurry up the system because you are probably the only one who can take advantage of it. If you learn to code and it takes 6 months, that is 6 months of lost profit potential.
Here is an analogy. Suppose you create a system for men to teach them how to improve themselves to help them get laid. Anyone who goes through the program and makes the changes, ie. hits the gym, buys new clothes, etc., will very likely find themselves being more attractive to women and their chances of success will increase tremendously. But suppose the program is simply the rental of a fast car, VIP status at a club, a dedicated entourage and a penthouse condo. Chances are, assuming this new identity, a guy can probably get laid that very same night. Going with the second option is like giving someone the secret sauce they can use right away. But going with the first option will require work from the customer and input of time. It won't be an automatic result.
Now clearly, giving away the first system will probably not affect anyone else from doing the same thing, it won't really dilute the edge too much, and it probably won't negatively impact the chances of the creator getting laid. But if you give away your fast car, condo and VIP access to a club, you may very well feel a bit cheated because this secret sauce was actually something tangible.
