Attached is a gif of an Excel chart that uses unique market 
  volume to try and predict short term market direction.  As the chart 
  indicates the market should be down for a significant part of the day for 
  Monday 3/12.
   
  I use Excel rather than Tradestation or Metastock because it is 
  more flexible in combining price & volume from multiple stocks / industry 
  groups.  However it is a labor intensive process to load data into 
  individual worksheets.  
   
  Can anyone please recommend a program where one can easily 
  combine price & volume from multiple stocks / industry groups?
   
  Thanks,
