My vision for building a Bloomberg-like trading terminal is to make it a one-and-done platform for research and trading, with the express goal of making a broad but very useful feature set.
Some of my most-used functions/features for equity research and discovery are EQS, SECT, and PORT. EQS (1st picture) is an equity screener that allows me to find new securities based on factors like the type of stock that it is, market cap, and country. SECT (2nd picture) is also used for discovery, but is categorized by GIC sectors to make getting sector-specific exposure in your portfolio easy. PORT (3rd picture) allows me to see correlations between securities, a security's portfolio weight relative to its risk, VaR, and even hypothetical shocks.
I've used each of these functions extensively to find stocks to start building a portfolio, though I feel like they can be improved and accompanied by other useful functions. If you trade or invest, what functions do you most often use, or would personally want in this kind of program?
