Thank you for getting the parallel strategy stuff working, this is a godsend to us. Now we're able to do around 8 strategies per core at a time, and we're still not pegging all 8 cores, nor are we IO bound. This is just beautiful.

There's two ways to do historical testing: one is in the gui, the other uses the TesterFactory class so you can do everything in a process of your own. We wrote an automated test framework we run on Amazon's EC2 service, so we spin up 100 or so servers and run through a few million tests in about a day.

Brian,
When you do this, do you have to "install" your java programs on amazon's servers? Or does your code just see amazon's servers as RAM?

Amazon has a few types of servers you can 'lease'. Among them, one uses a windows image and the other uses a *nix image. I have a *nix image configured to start up and immediately download an archive I've created with the requisite jars, downloads a pre-downloaded cache, and starts polling a server for strategies to test.
It's just like having a server setup, only I don't have physical access.

Brian i have an trying to test on these services i am running a backtest for over a year with approximately with approximately 20000 permutations and i want to know about approximately how long should that take on a large instance. Would you recommend switching to high CPU usage server as i noticed tonnes of the 8gb ram is free but the CPU IS PRETTY MUCH always at 100%.
