object name (string) + suffix (int) = trouble == SOLVED

vilem.iv 2021.11.27 18:54

string trend0 = StringConcatenate("trend0",_iTimeW1ST);
string trend1 = StringConcatenate("trend1",_iTimeW1ST);
string trend2 = StringConcatenate("trend2",_iTimeW1ST);

ObjectCreate(0,trend0,OBJ_TREND,0,_iTimeW1ST,step0,endTime,step0);
ObjectCreate(0,trend1,OBJ_TREND,0,_iTimeW1ST,step1,endTime,step1);
ObjectCreate(0,trend2,OBJ_TREND,0,_iTimeW1ST,step2,endTime,step2);

ObjectSetInteger(0,trend0, OBJPROP_COLOR, Green);
ObjectSetInteger(0,trend1, OBJPROP_COLOR, Green);
ObjectSetInteger(0,trend2, OBJPROP_COLOR, Green)

Hello, i've searched a lot but i was not able to figure out how to make cycle to manage object with numeric suffix (trend0 .... trend100, step0 ... step100).

Can someone help me with this in mql4 please?

I am sorry moderators i placed this in general topic instead to MQL4 by mistake.

Sure, the idea is this (cycle to avoid writing 100 rows):

for(int i=0;i<100;i++)  {
         string trend[i] = StringConcatenate("trend[i]",_iTimeW1ST);
         ObjectCreate(0,trend[i],OBJ_TREND,0,_iTimeW1ST,step[i],endTime,step[i]);
         ObjectSetInteger(0,trend[i], OBJPROP_COLOR, Green)
     }

This?

for(int i=0; i<100; i++)  {
  string trend = StringFormat("trend[%i]", i);
  ObjectCreate(0, trend, OBJ_TREND, 0, _iTimeW1ST, step[i], endTime, step[i]);
  ObjectSetInteger(0, trend, OBJPROP_COLOR, Green);
}

Thanks, however it doesn't work even the

OBJPROP_COLOR

does not work with

StringFormat("trend%i",i);

and ObjectSetInteger as object name. And how to use variable containing double value step1, step2, step3 .... step100 please?

double step[i];

Thanks, it looks like 1/2 problem solved, remain how to use variable containing double value step1, step2, step3 .... step100:

Declare the array somewhere:

double step[100];

// Do the calculation of the steps, I don't know how you are doing it since
// you didn't show the full algorithm.

for(int i=0; i<100; i++)  {
  string trend = StringFormat("trend[%i]", i);
  ObjectCreate(0, trend, OBJ_TREND, 0, _iTimeW1ST, step[i], endTime, step[i]);
  ObjectSetInteger(0, trend, OBJPROP_COLOR, Green);
}
