How to read the score
It describes the weighted balance of qualifying headlines. A score of 50 can mean balanced news or that there is not enough evidence; the status label explains which.
Confidence measures depth, source breadth, direct relevance, freshness and agreement. It does not rise merely because the tone is extreme.
Weekly price response, trend and fair-value position test whether the market is accepting or rejecting the news. They never rewrite the news score.
It measures news already published. It is not a forecast, recommendation or price target.
