Stock tracker

Years ago, I made up a clumsy spreadsheet that'd track some stocks throughout the day so's I'd see when to Buy or Sell. Alas, the spreadsheet ran continuously and my desktop PC was tied up. Yesterday I noticed my laptop, sitting unused. Then, as a consequence of creeping senility, I finally realized that I could let the laptop run all day (while I surfed on the desktop). So I generated another spreadsheet that'd track a couple of my favourite stocks and beep when the price hit some upper or lower price, like this: The prices are updated every minute or three: I'm looking forward to trying it out today. So why don't I just put in Buy and Sell orders? This is more fun! Besides, I have a hard time deciding whether hitting the upper price should be a Sell or a Buy. Is the stock headed UP, so I should Buy? Should I lock in my gains and Sell? I also had a hard time figuring out how to make the spreadsheet beep. It turns out to be a very complicated code, namely: If Range("C7") >= Range("G7") Then Beep Did I mention the thing about creeping senility?
