For starters, do you even know what a trading computer is? It is basically just an ordinary computer, but one that is built perfectly for day trading. A day trading system should be built simply for speed, and the fastest processing. Having said that, since trading laptop computers are primarily just regular laptops, they are not a good system for what you are looking to do.
Laptops are built for compacting purposes, and although today many laptops have sufficient processing speeds, desktops are still recommended for this type of use. Day traders spend their time buying and selling financial instruments, such as stocks, stock options, currencies, etc. So you can understand why the processing speed of their system they are using is of primitive concern.
The best day trading computers are usually based on reliability and dependability, because these are the most important components when testing if a system is capable of intense usage. It seems pretty dramatic, but the best trading computer systems, or at least the most desired by day traders, are the ones that can pass military testing. It does not matter, if a laptop, desktop, or a system of any kind, can pass military testing, it is safe to say that it will be one freakin efficient system.
It is too bad that trading laptop computers were not better for day trading, because then this would allow for more mobility, but in a job like this, it is not about where you are, or what your other capabilities are, it is only about what is on the screen. For a little tip, it is recommended that a day trader should use multiple screens, allowing them to see everything that they need to see at the same time.
The important aspect when day trading is assuring yourself that everything is being done in real time. The problems with slower systems is that they may face buffering and delay issues, which will affect the work being done. This can cause problems such as splippage, which is when the the true market price is different than the one being presented on your screen. This will lead to bad executions, and buying and selling will be thrown off completely, leading only to negative results, or loss in potential profits.
