Unfortunately this is a very deep and technical topic, so I won't be able to say everything in this article. However, I will be writing a lot more about this in the future as my prior industry experience in the financial industry was chiefly concerned with financial data acquisition, storage and access. In the previous section we had set up a strategy pipeline that allowed us to reject certain strategies based on our own personal rejection criteria. In this section we will filter more strategies based on our own preferences for obtaining historical data.

It does not include stock price series. Some fundamental data is freely available from government websites.

Machine learning algorithmlc such as classifiers are often used to interpret sentiment. This data is also often freely available or cheap, via subscription to media outlets. The newer "NoSQL" document storage databases are designed to store this type of unstructured, qualitative data.
