Question: I am currently working on a large data set (approx 80 million data points over 10 years). I would like another set of data that has one currency in common. Eg, I have EUR/USD and would like USD/CNY or EUR/AUD etc. Doesn't need to be over the full 10 years, 1 year would be more than sufficient.

I found a few places online that sell this data, but the cheapest I could find was approx 60 Euros which is a lot for a student.

Is there anywhere someone can get data like this cheaper?

Answer: 
You might get something from [Integral's True FX](http://www.truefx.com/)
Take a look as well at [TickStory Lite](https://tickstory.com/product/tickstory-lite/). 

IIRC, you should be able to pull tick level FX transactions back to 2003 for free. I used this several months ago, so not sure if anything has changed.
