The main aim of Pivots indicator is to analyse concrete TIME period.
As you know, Price Bars and PnFs have no any time period. The data is aggregated by PRICE not by time.
So there is no point in Pivot indicator for those charts at all. That is why Pivots doesn't appear.
https://en.wikipedia.org/wiki/Pivot_point -" A pivot point is calculated as an average of significant prices (high, low, close) from the performance of a market in the PPRIOR TRADING PERIOD".
