Hi coders, please advise how to get the iTime automatically for other respective timeframe's datetime ? datetime iTm=iTime(sym,PERIOD_M1,15); // Shift=15 Print(TimeToStr(iTm)); // Output : 2025.02.14 18:57 Note that the above example of "PERIOD_M1" is not fixed, I may use other period for my purposes. If the Print output is "2025.02.14 18:57", I should expect a set of codes to get me the following answers automatically for respective timeframes such as :- M5 : 2025.02.14 18:55 M15 : 2025.02.14 18:45 M30 : 2025.02.14 18:30 H1 : 2025.02.14 18:00 H4...

    datetime currentbar = 0;
    
    currentbar = iTime(Symbol(), PERIOD_M5,  0);  //current M5  bar time
    currentbar = iTime(Symbol(), PERIOD_M30, 0);  //current M30 bar time
    currentbar = iTime(Symbol(), PERIOD_D1,  0);  //current Day bar time
