Calculate percentage change of cell

Is the cell being updated through some sort of external feed??

mround sort of works. But it rounds the value up too, so not exactly what I wanted, but thanks, might do if nothing else comes up.

Say the cell being refreshed each second is cell B9. Pick an un-used cell and enter:

=B9

This cell insures that the worksheet gets re-calculated whenever B9 get refreshed. Now we need to capture instances in which the data grows by more than 5%. We will use column C for this purpose. Change the assigned cells and logging column to meet your needs. Install the following event macro in the worksheet code area:

Because it is worksheet code, it is very easy to install and automatic to use:

1. right-click the tab name near the bottom of the Excel window
2. select View Code - this brings up a VBE window
3. paste the stuff in and close the VBE window

If you have any concerns, first try it on a trial worksheet.

If you save the workbook, the macro will be saved with it.
If you are using a version of Excel later then 2003, you must save
the file as .xlsm rather than .xlsx

To remove the macro:

1. bring up the VBE windows as above
2. clear the code out
3. close the VBE window

Macros must be enabled for this to work!
