I have the same problem. I posted this: https://www.elitetrader.com/et/threads/prediction-based-trading.351176/page-42 to show half a year of trades called with live entry and exit but nothing. I have recently made one online: https://collective2.com/details/134463089 to see if a fund will accept so we'll see what happens. I assume they'll want a track record.
Your strategy is not scalable to billion+ as your holding time is just a few minutes typically. That's just noise, in no way you can apply large sums of money on that.
