I'm a software engineer who's created a stock trading application that consistently doubles investments within every 2 years, trading in simulation on historical data. I've just been entrusted $10,000, to prove the application works on eTrade.

My current investor is guaranteed 7% annual profit, plus a split 50/50 of all additional annual profits from the application. New investors are guaranteed 15% annual profit, with 50/50 split above.
