Build data driven models

building data driven algorithms and models to apply during an investment process. I’m currently looking to hire someone to help me build or understand products and services that are already out there servicing the quantitative side of the financial markets. The objective here is to as most accurately as possible identify when a security falls, how often it falls and how much it falls by on average and then vice versa for the upside. How much it rises, how often and when. This is to find patterns, and collect that data for more reference in the future. My question is it feasible for someone to build such a program?
