Machine Learning + Retail Forex = Profitable? (Quant)

To Quant Traders:

Has anyone successfully developed a profitable machine learning model for retail forex trading?

All I know quant traders use machine learning for hedge funds/banks but I wonder if there are opportunies for retail forex?

Or are we better off spending our time developing a system elsewhere?

Yes I am currently live with two models and tweaking another before it goes live (all three are in FX). I must add that what makes FX harder is that it is a zero sum game and the only way to bring in fresh money is through capital inflow and outflow. That would be large international investors moving money into a country to invest in stocks and bonds, usually this is what causes fundamental data to be so critically important.

I currently have a thread demonstrating these systems if you are interested.
