Hello, can you tell me if it's possible to connect a copying signal and a robot to an mt4 account and connect all this to the vps?

Yes of course you can!!!

Hi guys. Can you advise someone who is perfectly familiar with programming?

I create a horizontal line under certain conditions. I define a price with OLB in order to use OpenlineB in another code as the price of the horizontal line. In another code where it is needed it is displayed as an integer. For example the price is 110,256 and it shows 110. I found this out with Comment. Why is the exact price not displayed, what is the problem?

int OpenlineB() {
    double ma60=...;
    double ma=...;
    if((fMarketOrders(OP_BUY)==0)) { 
         ObjectCreate(0,"BUY",OBJ_HLINE,0,0,ma60+ma); }   
 int OLB=ObjectGet("BUY", OBJPROP_PRICE1);      
 return(OLB);}

int TRlineB(){
Comment(OpenlineB());
return(true);}

int double OpenlineB()

Your function returns an integer number. What you get is what is printed.
And of course, further on in the function you convert it to double format.

 int OLB=ObjectGet("BUY", OBJPROP_PRICE1);      
 return(OLB);}

Already tried it. It returns an integer.

int OpenlineB() {
    double ma60=iMA(NULL,1,5,0,1,0,1);
    double ma=(iMA(NULL,60,6205,0,1,2,1)-iMA(NULL,60,6205,0,1,3,1));
    if((fMarketOrders(OP_BUY)==0)) { 
         ObjectCreate(0,"BUY",OBJ_HLINE,0,0,ma60+ma); }   
 double OLB=ObjectGet("BUY", OBJPROP_PRICE1);      
 return(OLB);}

I got it!!! Thank you dear Konstantin!!!!!!!!!!!!!!!!!!

Try using ObjectGetDouble
And change the function declaration to

double OpenlineB() {

[Rustam Bikbulatov]

Konstantin Nikitin:

Try using ObjectGetDouble

All done!

double OpenLineB() {
    double ma60=iMA(NULL,1,5,0,1,0,1);
    double ma=(iMA(NULL,60,6205,0,1,2,1)-iMA(NULL,60,6205,0,1,3,1));
    if((fMarketOrders(OP_BUY)==0)) { 
         ObjectCreate(0,"BUY",OBJ_HLINE,0,0,ma60+ma); }   
 double OLB=ObjectGet("BUY", OBJPROP_PRICE1);      
 return(OLB);}

Thank you!!!

All done!

Thank you!!!

Can I truncate it a bit?

double OpenLineB() {
  double ma60=iMA(NULL,1,5,0,1,0,1);
  double ma=(iMA(NULL,60,6205,0,1,2,1)-iMA(NULL,60,6205,0,1,3,1));
  if(fMarketOrders(OP_BUY)==0) 
   ObjectCreate(0,"BUY",OBJ_HLINE,0,0,ma60+ma);
 return(ObjectGetDouble(0,"BUY",OBJPROP_PRICE));
}

Vitaly Muzichenko:

You could truncate it a bit.

double OpenLineB() {
  if(fMarketOrders(OP_BUY)==0) {
    double ma60=iMA(NULL,1,5,0,1,0,1);
    double ma=(iMA(NULL,60,6205,0,1,2,1)-iMA(NULL,60,6205,0,1,3,1));
    ObjectCreate(0,"BUY",OBJ_HLINE,0,0,ma60+ma);
    return ma60+ma;
  }
 return(ObjectGetDouble(0,"BUY",OBJPROP_PRICE));
}

otherwise indicator data is called from cache at every access
And it would be better to keep the level of "BUY" line in your variables and not look for it on the chart.
