I have a spreadsheet that is tracking stock prices. The cell with the price
is fed by a DDE link.


Stock Price
AIG 100
AXP 100
AMAT 100
AMGN 100
AMD 100

I am trying to create a visual monitoring tool. I was hoping to have the
cell (ColB) change color (any color will do) everytime the price changes.

For example, if the cell initially is no color, on the first change, color
switches to green, on the next change, back to no color, on the 3rd price
change, back to green etc.

Is this type of thing possible ?

Thank you in advance.
