Referring to daily open on minute chart

[fiddy]

How would you refer to the daily open on a minute chart

I have added the daily data
Add(PeriodType.Day, 1);


Now I want to be able to say:
if daily open is lower than yesterdays low

Open[1][0] < PriorDayOHLC().Low[0]

Will this work?

fiddy, for this case I would reconsider adding daily data at all, since the open would be given as well from the intraday data via CurrentDayOHL().CurrentOpen[0] which I would use for the comparison then.
