Here is a link to a file of tickers named x, y, z,w containing

10 sin(i/10),    10 cos(i/10),    10 cos2(i/10)sin(i/10)+10 cos(i/10),    and  10 sin 2(i/10)-10 cos(i/10)-10.


for i=1 to 400. Right click proof2.txt and choose 'save target.' Set the ticker names x,y,z,w and file position numbers 1 (blank) 2 (blank) as in the screenshot below. Press the File: button, select 'Browse for new file' and locate the file proof2.txt which you have just downloaded.

The fact that these are repeating functions is just so the viewer can recognize whether the predictions are correct. The program does not use the fact that they are repeating functions. Note that since the DAYS slider is set to 21, the predicted change is given 15 data points ahead, as the DAYS slider is in terms of actual days not including week-ends, so it will state that the prediction is for 15 business days in the future.
