Quote change # histogram

[dtatrade]

I would like to see the number of quote changes in histogram, similar to a normal volume histogram. I have no EFS programming experience. I tried the Formula Wizard, but this doesn't seem to be a "data point" option.

The bidaskanalysis.exe on this page is similar to what I want. Maybe the input can be easily altered from volume to quotes?
