source_track_record
How often was a news source right, against chance?
Hit rate of a financial news source (how often its articles' tone matched the later price move at 1, 3 and 7 days, measured from the first tradable price), next to chance for the same mix of calls, with a 95 % interval and a verdict (better than chance / not distinguishable / worse / too few data). Without 'source' it returns every source. Descriptive only: not a return, not a forecast, not a recommendation. Always show the user the disclosure and the links.
