I develop trading systems using Right Edge Systems <[login to view URL]> and their software has the ability to develop plug-ins to do further work.
I am after a plug-in to dp Monte Carlo testing on the results that my trading systems produce.
The monte carlo results will draw an equity curve for each set of results to see the possible results that may occur.
THere are sample plug-ins already in the download so you can see how they work.
It can be coded in C# or vb.net.
There may be more work (plug-ins) as well
