I ran some numbers for you that make more sense than a win loss ratio.
I started with 10K, 2500 for each stock.
If the prediction was for a lower close the next day I sold short.
If the prediction was for a higher close I bought.
I closed and reversed a position when the prediction changed. (So for AMD I sold at the close on Oct 9 , Reversed my position on Oct 15 and Oct 21 and am now short.)
I didn't use stops or profit targets. It kind of looks like if I did the loss would have been greater.
As it turned out if you cashed in tonight you would be down 2.26%.
If you had just bought and held SPY you would only be down 1.19%
