charlie, CMF in the other post is all positive, that is to say "green", because it's only a 6-month chart and FASC's CMF has been positive "green" for that whole time. CMF does oscillate around a zero-line, here's the daily 1-year FASC chart that shows a brief "blip" of negative CMF so you can see the oscillation.
And one last thought. Pay no attention to the assertions of some that CMF is not useable on low-volume, low-price stocks. It is useable, it does work, and I have the bank account to prove it from having used it for over a decade with just such stocks.
Some people make the mistake of believing that just because they're not able to do something successfully, no one else can, either.
