Right now, for each bar, it puts one cloze in the array. And if I don't do that, then I have to calculate from which bar to collect data, loop and filter. And this leaves only the latter.
 
gince:

I don't know how many elements an array should have. It could be 40 or 65. In a word, we need a dynamic array.

Use ArraySize to change the size of the array:

int start()
  {
//----
   int start=3;
   int end1=30;
   int end2=90;
   int array[];

     ArrayResize(array, (end1-start) );
     int size1=ArraySize(array);
     ArrayResize(array, (end2-start) );
     int size2=ArraySize(array);

   Comment("start=",start,", end1=",end1,", end2=",end2,", size1=",size1,", size2=",size2);
//----
   return(0);
  }
In the comments it comes out: start=3, end1=30, end2=90, size1=27, size2=87.

Good afternoon, Please help, the robot with 0.1 lot multiplies volumes and with 0.01 does not.... What can I change?


And there is a bed! SRC! To insert the code!

I'm not very good at it yet... tell me what to do....

 

Using the SetTLine() function from KimIV https://forum.mql4.com/ru/38949/page6#434255 . The problem is that I need two lines (top and bottom), but it doesn't work for me. Made another function SetTLine1() with other variables, but it still doesn't work. How to do it?

datetime d0=StrToTime(TimeToStr(TimeCurrent(), TIME_DATE));
datetime d1=TimeCurrent()-24*60*60;
while (TimeDayOfWeek(d1)==0 || TimeDayOfWeek(d1)==6) d1-=24*60*60;
d1=StrToTime(TimeToStr(d1, TIME_DATE));
datetime d2=d1-24*60*60;
while (TimeDayOfWeek(d2)==0 || TimeDayOfWeek(d2)==6) d2-=24*60*60;
d2=StrToTime(TimeToStr(d2, TIME_DATE));
int b2=iBarShift(NULL, 0, d2);     // номер бара начала второго дня
int b1=iBarShift(NULL, 0, d1);     // номер бара начала первого дня
int b0=iBarShift(NULL, 0, d0);     // номер бара начала текущего дня
int n2=iLowest(NULL, 0, MODE_LOW, b2-b1-1, b1);
int n1=iLowest(NULL, 0, MODE_LOW, b1-b0-1, b0);
datetime t1=Time[n2];
double   p1=Low[n2];
datetime t2=Time[n1];
double   p2=Low[n1];
SetTLine(Magenta, "", t1, p1, t2, p2, True, STYLE_SOLID, 3);   

datetime di0=StrToTime(TimeToStr(TimeCurrent(), TIME_DATE));
datetime di1=TimeCurrent()-24*60*60;
while (TimeDayOfWeek(di1)==0 || TimeDayOfWeek(di1)==6) di1-=24*60*60;
di1=StrToTime(TimeToStr(di1, TIME_DATE));
datetime di2=di1-24*60*60;
while (TimeDayOfWeek(di2)==0 || TimeDayOfWeek(di2)==6) di2-=24*60*60;
di2=StrToTime(TimeToStr(di2, TIME_DATE));
int bi2=iBarShift(NULL, 0, di2);     // номер бара начала второго дня
int bi1=iBarShift(NULL, 0, di1);     // номер бара начала первого дня
int bi0=iBarShift(NULL, 0, di0);     // номер бара начала текущего дня
int ni2=iHighest(NULL, 0, MODE_HIGH, bi2-bi1-1, bi1);
int ni1=iHighest(NULL, 0, MODE_HIGH, bi1-bi0-1, bi0);

I don't understand it very well yet... tell me what to do....

SRC is here:


And if the code is very large, as in your case, attach the file:

I answered you in the other thread! And delete your "portmanteau" posts!
 

Now the error is 130, I don't understand why. Who can tell me where I'm going wrong.
