I have had many questions on what type of hardware setup a trader should have. My answer is always this depends on your focus but below I have a few basics I believe are necessary regardless of your focus.
I highly recommend 2-3 monitors minimum, in the end they save you time and the more monitors the more eyes you can have on the market. Personally I run 6 screens. Below are a few Cheaper Monitors, external video cards to connect them, stands and etc.. I would recommend. (clickable)
External Video Cards:
Key Board (Mechanical and Gaming For Hot Keys best Imo):
Ram 32gb Min Imo (check compatibility of-course):
Internal Video Cards (plenty of different options depending upon what you are doing but bulky ones->):
