title: High Frequency Trading
body: <p>Over the last couple of weeks i have come across lots of articles about high frequency trading. They all talk about how important computers and software is to this but since they are all written from a financial point of view there is no detail about what does software do?</p>
  
  <p>Can anyone explain from a programmers point of view what is high frequency trading? and why is computer/software so important in this field?</p>
