P&F charting problem

From time to time my P&F chart overlying the daily/weekly price chart seems to stop in the past at verying time gaps.
For instance, a perfectly formed daily price chart up until today will have a P&F chart that seems to stop years ago (I am looking at one for EL8 that stopped in 2010).

I would like to understand the reason for this and to correct it if possible. A P&F chart is central to my trading method.

Hi Bill,

I’m not sure how the P&F chart is being overlaid on a price chart as they are calculated very differently.
