How to look back and identify the 1st hour of the previous day ?

[Gannyyo8]

Hi every one please help.
I try to search but not exactly found the method.

Example: For now not specific time. I need to get OHLC price level of 1st candle of previous day (plan to use Day CandleID to identify date want to look back) but I cant' identify the 1st hour bar of the Day candleID.

try to use hour filter but that mean we can limit the period that allow EA work some command. can't use to look back. please advise.
