I use R. Check out quantmod, FOSS Trading (my blog), and Rmetrics. Hopefully that gives you an idea of what you can accomplish with R.

I can't compare these tools to JSystemTrader or JBookTrader, since I have no experience with either of those packages. All I can say is the two Java packages seem geared toward developers, and the R packages are aimed more toward end-users. Though I'll concede that R has a steep learning curve...

You're most welcome. I didn't think you were belittling it, but I did want to know if you thought it should do something that it doesn't currently do. If you have questions, you can contact the package maintainers (for any package) or post on the R-SIG-Finance mailing list. You'll need to...

What kind of "trick" do you expect? It's not "special" in the sense that it does something other software doesn't, but it's the only publicly-available way to run transaction-oriented trading simulations in R. "Heavy development" means "not optimized for speed", among other things. Try...

It's not a mature set of tools, but I'd encourage you to check out the following R packages: quantmod, xts, TTR, IBrokers, PerformanceAnalytics, and blotter. Unfortunately, blotter is still in heavy development (you can find it on r-forge).

You could also check out rinside. EDIT: wow, you must be contagious... :p nothing like suggesting something you had already considered.

There's nothing wrong with that. You assumed answers to the questions I asked, and those assumptions may be totally reasonable. I'm less comfortable making those assumptions and I've found that asking questions usually results in being able to provide better answers. Cheers.

Why do you think he would compile an application while trading or use his PC as anything other than a dedicated trading station? He, nor anyone else, has suggested that. You missed my point. If his software is I/O-intensive, HDD speed would be a bottleneck. If his software is...

It's really hard for me to say because I don't know the potential needs of the software you're using. As I said before, I would want to know if this were really a hardware issue before advising you to buy a new PC. Though, if you're looking for a reason to buy a new PC, the prior point is...

This isn't categorically true; it depends on the process that's running. If the process is I/O intensive, a faster HDD will matter more than CPU speed. E.g. building a particular software package takes 25 minutes on my 2.2Ghz laptop with a 5,400 RPM HDD. Building the same software takes 8...

Are you sure this was due to a hardware problem and not a software problem? New hardware may be an expensive solution to a problem that could be solved by simply reinstalling your operating system (I'm assuming you're running some version of Windows). Even if it is a hardware problem, it...
