Is there an "official" way we can get access to more history data? I don't mean more history of what we already have on your Download page, but specifically more pairs.

For example IBFX has at least 27 tradeable pairs and I noticed FXCM has even more. In my discretionary trading, I found that some exotics just don't seem to work well, but others work great. I'd love to throw Zorro at them and see what it can uncover...

I'm willing to do the heavy lifting and gather/process/sort this data, to make more available for other users to easily Download. In the past when I've manipulated tickdata I've taken the raw source (usually .csv) and imported it into a MySQL table for analysis/cleanup. In this form it can also be (relatively easily) shifted to Zorro's UTC upon export and non-essential info stripped.

My biggest question for you is regarding licensing / legality restrictions. If we assume that the data itself is generally clean/error-free... is there still any issue with providing the data back in a cleaner format ready for import to Zorro?

I've found several "free providers" of data. I'd greatly prefer to use FXCM's data (mostly since it's a known trustworthy source) but it seems you have to purchase their data downloader tool which I'm unable to do. Also, I'm not sure if they have restrictions on redistribution.

One free and comprehensive provider is http://www.histdata.com/ but my impression here is that this is not "legally redistributed" data.

There are many other providers as well.
