I am going to be trading equities; therefore, it is a tremendous advantage to have a considerable amount of information, in my view, at the same time. I designed and built a desk that has 4 32" 4K monitors, which allows me to have as much data as 16 1080P monitors, right in front of me. I couldn't imagine having 16 monitors, one would have whiplash by the end of a trading day. The desk is a stand up/sit down desk, ergonomically designed so that the bottom of the monitors are lower than a standard desk, lower than the keyboard. I see so many pictures of traders with the monitors higher, causing them to tilt their head up, which causes incredible neck strain. The monitors are configured and tightly attached so that I barely have to move my head, just my eyes, to view all of the data.
I built a "kick ass" computer because of the large amount of data that is streaming in real time onto the 4K monitors. I do understand that trading other instruments, such as futures, does not require the system that trading equities does in order to have an edge.
