Whether you like/believe in technical analysis or not, it’s worth knowing that in most bank treasury departments just about every dealer uses charts – daily. Terminals like Bloomberg and Reuters made their money transforming raw data into something visual, data that can be manipulated in many ways; rental of these machines funds their newswires, TV and radio stations.
Visualisation is a well-known, powerful communications tool, infographics are widely used in publishing. Histograms and pie charts representing people’s and nations’ characteristics, distribution and tendencies. Line charts showing the increase in a company’s share of the market or net profits. Maps shaded for temperature and rainfall. You know the kind of thing. That is not technical analysis.
