Trading System Research and Development - US Stock Index MT4 Ninjatrader

This job is research/development. I want to research how the POMO (Permanent Market Open Market Operations) of the USA's Federal Reserve effect stock index levels. To be more precise, when the fed is 'buying', I want to research how this effects trade entry results for a specific kind of market entry. So the job will be firstly getting data on POMO (easy to get online for free), then using this as a filter. Then investigate how a certain trade entry is effected by the POMOs that are going on. I want this research for the last two years of data.
