I see so many retail stock traders having 3-4 different screens showing different graphs and charts Is it necessary? It looks so fancy and complicated. Won’t a trader using only 1 screen be successful?

Because professional traders did it [first](https://en.wikipedia.org/wiki/Bloomberg_Terminal#/media/File:2012_Bloomberg_Terminal_by_jm3_-_Creative_Commons_licensed.jpg).
Professional traders use multiple screens because their profit mostly comes from having information faster than others, so having many screens means more information can be gathered and processed faster than with only a single screen. It also makes it easier to compare prices from different sources to quickly spot little mismatches in prices that can be exploited for small profits.
