If you really have the edge you say you do, just trade it yourself. Managing other people's money is fraught with problems and headaches.
I really don't understand this. Why would you contact google finance? What do they have to do with anything? Why would they want to help you "certify" your research?
I had a system quite similiar to yours. It failed because I could not buy in at the opening price as often as I thought. It is one of the many failed trading systems I designed.
Did you set a (MOO) market on open order, before the market opens, I always get the opening tick with them.
What you showed does not disprove random walk theory, which captures the essence of markets, and is an acceptable and very solid theory. It should be a starting point for you to design winning methods as long as your trading size is small.
