EVE Technology Lab

What might be feasible for you is to use the Eve Marketeer unified uploader, sending it to a custom endpoint.

I've got something working that way, and it's doing at least some of the work for me.

There's a quick list of instructions on my site for getting XAMPP working (to get a copy of php, apache and mysql on your local machine, along with a copy of the eve Static data dump) and in a separate zip file, there's a quick and dirty uploader endpoint, which the unified uploader can use to dump market information into that mysql database. right now, all it does is toss the records into mysql. Which means over time it will have the same order in there multiple times. Though that could be useful for trend analysis.

I have no clue how to do it in C++

The eve central cache reader is open source though, and uses libevecache. You might look there for pointers on how to start.

That said, why use C++? The python implementations are a lot easier in my experience. Even if you do not know the language, after C++ it should be extremely easy to learn.

C will probably be faster on th analyzing though :P
