Added a separate setting for displaying "number of CPR back" so that you can display previous CPRs without displaying previous pivots.
Useful for checking two-day relationships between CPRs which can give you a directional bias as discussed in Franklin Ochoa's book "Secrets of a pivot boss".
For example if the CPR of the current day is higher than yesterday's CPR and price opened above today's CPR that will generally give you a bullish bias for the day (and same for weekly, monthly pivots etc).
There are 7 different types of two-day pivot relationships, I recommend you to read the book or do some research online to learn more.
