2. The following might get you started.

When dealing with time, a lot of people use strings; they can not be optimized. Using (int) seconds or (double) hours, or (int) hours and minutes can be.

Find bar of the same time one day ago - MQL4 programming forum (2017)

i have had many attempts ,at least 20 attempts,i just didnt want others to have complicated ideas while thinking ,maybe sb has an easy way to solve.

here is the main attempt:

int H1730=63000;

int H2330=84600;

int h=Hour();

int m=Minute();

int SecsPassedFromDay=(h*60*60)+(m*60);//ثانیه های گذشته از از دوازده شب

if( Seconds()==0 && SecsPassedFromDay>H1730

&& SecsPassedFromDay<H2330 )//ساعت بعد هفده و سی و قبل بیستو سه و سی  و ثانیه صفر هر دقیقه

{

int shiftOPNYinMins=(SecsPassedFromDay+(30*60))/60;//قیمت یازده و نیم شب یعنی باز شدن آمریکا

double ONYP=iOpen(NULL,PERIOD_M1,shiftOPNYinMins);//قیمت یازده و    نیم شب در یورویواسیعنی باز شدن

Print("ShiftopnyinMins  = ",shiftOPNYinMins);

Print("ONYP  = ",ONYP);

Print("Time0  =",Time[0]);

Print("secpasedfromday  =",SecsPassedFromDay," > ",H1730," & secpasedfromday= " ,SecsPassedFromDay," <",H2330);

}

These assume every bar every exists — they don't. What if there are no ticks during a specific candle period? Especially the first second of a new bar. There can be minutes between ticks during the Asian session, think M1 chart. Larger charts, think weekend, market holiday (country and broker specific), requires knowledge of when your broker stops and starts (not necessary the same as the market.)

4. ```int H2330=84600;
datetime bod=date();
int      tod=time();

if(tod < H2330) bod=yesterday();

int shiftM1=iBarShift(_Symbol, PERIOD_M1, bod+H2330);
return iOpen(_Symbol, PERIOD_M1, shiftM1);```

thank you for your precious time,

my expert is writing, i am looking for ANOTHER solution.

just last question,

my meta4 does not have these two as predefined

```datetime bod=date();
int      tod=time();```

date()

and

time()

how can i get them

date() and time() are functions that you need to write...
