Eli5: why do retail stock traders have several screens and is it necessary to have more than 1 to trade successfully?

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?

Sure, but this is a bit like asking “Why do people have 25-inch monitors? Couldn’t you be productive with just a 15-inch one?” You don’t *need* the extra space, but it is useful to be able to see and manipulate more information in a given amount of time than you’d be able to on a smaller screen — or on just one screen.

With traders, for whom time is of the essence, any advantage they can gain in terms of the speed of their decision-making is (in theory) going to help them make more money.
