Hi,
I have been using your code especially the sentiment portion and found it very insightful.
As for the last portion where you predict using neural networks with sentiment, I am not seeing the results to be that accurate.
In your case, did you test this on multiple tickers to see which one was the most accurate before choosing the ticker in your example based on this model?
I also broke out the sentiment by category such as technology, usa, business, etc.
Overall very helpful though!
