Just getting started–what’s a quick way to test pair trading if one pair is not on the market?

For example, let's say that I want to compare:

1. The # of people that search "bitcoin" on Google
2. The price of BTC/USD

Let's assume I can pull the data from Google just fine. Is there a python library already out there (or any language–Python just seems popular here) that makes it easy to compare these and test with some different EMAs and whatnot?

Note: I know this is probably a popular example and is not the one I intend to test. I'm also mindful of over-fitting.
