First download your free copy of GoldenGem, also click on the data file proof.txt. It contains sin(i/10)^3+.001, cos(i/10), (sin(i/10)^3+.001)^2+ 6 cos(4 cos(i/10)), and sin(5 (sin(i/10)^3)cos(3(cos(i/10)) for i=1 to 400, and fictitious tickers x,y,z,w. Look at the screenshot for the result. It predicts them perfectly. And you can try it yourself for a very convincing proof of why GoldenGem is the one which was chosen.
