1. There is no bar "that have a value = at XXX" Bars have four values (OHLC,) and four ranges. Your image points to the first candle totally above current market. Until you can state your condition in concrete terms, it can not be coded. First, latest, above, below, crossed, closed above, etc.

2. Get the index for the beginning of the day (BOD), last bar of previous day (EOY) index for previous day (BOY.) Loop over the bars and check your condition.

int LastTimeBar(){
int output = 0;
for(int i = 0; i < iBars(NULL, TimeFrame); i++){
if(TimeHour(iTime(NULL, TimeFrame, i)) == (int)StringSubstr(ReferenceCandle, 0, StringFind(ReferenceCandle, ":")) && 
TimeMinute(iTime(NULL, TimeFrame, i)) == (int)StringSubstr(ReferenceCandle, StringFind(ReferenceCandle, ":")+1, 2)){
output = i;break;}
}
return output;
}

The function 

LastTimeBar()

 will give you the candle index of your ReferenceCandle (xx:xx)

TimeFrame is self explantory.
