This is a follow-up to the question: How does the bloomberg website chart calculate the MACD?
When selecting a quote in the Bloomberg Market site (e.g. this quote), you are given the choice to add several indicators apart from the MACD. One of them being the "Rate of Change" (ROC).
I would like to know how it is calculated since the values shown don't seem to match the typical definitions for rate of change.
