you must use PERIOD_H4  chart property in iTime function and specify a bar index

The time of the bar will be the same as the date.

if( Time[i] == date(Time[i]) ) …

          Find bar of the same time one day ago - Simple Trading Strategies - MQL4 programming forum

The above fails on brokers that have a single 4 hour bar on Sunday.

int i = iBarShift(_Symbol, _Period, date() );
 

To be more specific, here's what I've tried:

1) I have the index (Idx) of the current H4 bar. In order to determine the start time of the current Day:

datetime v_StartDayTime = iTime(Symbol(), PERIOD_D1, Idx);


2) Now if I try to find the corresponding index of H4 bar for v_StartDayTime:

int v_Idx_H4 = iBarShift(Symbol(), PERIOD_H4, v_StartDayTime);


3) Print the Time[v_Idx_H4 ]  , but there's no H4 bar for this time

  1. The index of the H4 bar can not be used as the index of the D1 bar. You are mixing apples and oranges.

  2. On MT4: Unless the current chart is that specific pair/TF referenced, you must handle 4066/4073 errors before accessing candle values.

    The function linked to, opens a hidden chart for the symbol/TF in question (if not already open,) thus updating history, and temporarily placing the symbol on Market Watch (if not already there,) so SymbolInfoDouble(symbol, SYMBOL_BID) or MarketInfo(symbol, MODE_BID) don't also return zero on the first call.

 
You didn't answer my question: given a H4 candle how do I determine the first H4 candle of that day ?

I did answer that in #2 and gave two different solutions.

 
Thanks.
