What publicly available software do professional stock traders use for stock analysis?
Bloomberg is very popular, especially for researching individual companies. Market QA and Factset are popular for analyzing data. Microsoft Excel and Matlab are very common for analyzing the data.  Lots of time traders will take data from Bloomberg, Market QA, Factset or where ever, and then actually preform their analytics in Excel or Matlab. A lot of the brokers provide their own software to traders using their platform, and that software can also contain different tools to help the traders as well.
