Hello, I'm a business journalist working with Trombly Ltd, a news bureau based in Shanghai, China. I'm currently writing an article about online trading. The idea of the article is to provide first-time traders with information which PC hardware is commonly used by more experienced traders. Can anyone help me with the following: -firewall? -back up power system - what is out there in the market - cost? -security issue (esp. if one is using a wireless laptop) -instructions to set up 2 monitors (most active traders use more than one monitor) -other trading station - computer compatibility issues I'd highly appreciate your help. Many thanks.
