two PivotPoints in different data，how to getvalue at same datetime?

[magieva]

I have two datas,1hour,1day.

cerebro.resampledata(data, timeframe=args.timeframe, compression=60) #1hour
cerebro.resampledata(data, timeframe=args.timeframe, compression=60 * 24)#1day

two PivotPoint in startegy:

self.pp = PivotPoint1(subplot=True)
self.pp_day = bt.ind.PivotPoint(self.data1, _autoplot=True)

when I get self.pp.lines.p[-20],
How can I get self.pp_day.lines.p[?] ,?=bar index ,
at the same datatime （self.data0.datetime.datetime(-20)）？

Thank you very much.

Since your other compression is 60*24 and 24 > 20, the answer is 0 (and depending on the stage of the resampling even partially 1, which is actually the future)
