If you think it is decent to have several screens at the same time, you can add two screens to display them separately. Pay attention to both futures market, spot market and foreign exchange market.
I have been trading stocks for some years, and I have never placed an order in the trading hall ... mainly because I don't have time to go to a brokerage firm. Telephone transactions and online transactions have been used.
In addition, I will give you some personal advice: only retail investors will wander in the trading hall. In this case, there will always be endless voices around you to convey your greed and fear. Over time, you are also prone to become a standard small scattered, subconsciously affecting you. So I don't recommend you to be a professional investor in the trading hall.
You are playing stocks, not stocks.
