Which method is fast and resource friendly for multicurrency scanner?

Please explain your method for using objects or Global Variables in such a scanner .

I don't know Russian, but I very much doubt that "Multicurrency" is a Russian word.

Please explain how an object can be converted into a buffer from a multi-symbol scanner.

Please explain how GlobalVariableGet and GlobalVariableSet can also be used from a multi-symbol scanner.

I have already asked for explanations of your methods and you have not clarified.

The only way that I see this is possible would be to have charts open for every symbol being scanned and each chart having an indicator running to create these objects and Global Terminal Values. To access objects on another chart, the scanner would also have to know the chart id. This seems rather clumsy to me.

kindly read this

 for objects to Buffer convert, see this simple code

double Up[1];
double Price2=NormalizeDouble(ObjectGetDouble(0,Name,OBJPROP_PRICE,1),Digits());
       
            UP[0]=Price2; // Buffer

double Price2=NormalizeDouble(ObjectGetDouble(0,Name,OBJPROP_PRICE,1),Digits());
       
            UP[cont1]=Price2; // Buffer

Yes, I know how to use Global Terminal Variables and I have converted a number of indicators to use buffers instead of objects.

double Price2=NormalizeDouble(ObjectGetDouble(0,Name,OBJPROP_PRICE,1),Digits());

Note that the above code gets the value of an object that is on the current chart. Not very useful for a multi-symbol scanner.

You still haven't answered my questions.

Ok, a simple exercise for you.

Create a simple indicator to get values using an object and a GV for a symbol that is different to the symbol that the indicator is attached to. Bear in mind that there may not be a chart open with the  relevant symbol and time-frame.

first we have to draw the object to multi symbol then we can convert into buffer, example

int total = SymbolTotal(true);
double price1,price2,PriceBuffer[];
for(int i=0;i<=total;i++){
string sym = SymbolName(i,true)
ArrayResize(PriceBuffer,total);
ArraySetAsSeries(PriceBuffer,true);
price1 = iClose(sym,PERIOD_M5,1);
ObjectCreate(0,"line1",OBJ_HLINE,0,0,price1))

if(ObjectFind(0,"line1")>0) price2=NormalizeDouble(ObjectGetDouble(0,"line1",OBJPROP_PRICE,1),Digits());
Pricebuffer[i] = price2;


}

for Global Terminal Variables, we can store symbol name, price using iClose and can run a scanner

int total = SymbolTotal(true);
double price1,price2,PriceBuffer[];
for(int i=0;i<=total;i++){
string sym = SymbolName(i,true)
ArrayResize(PriceBuffer,total);
ArraySetAsSeries(PriceBuffer,true);
price1 = iClose(sym,PERIOD_M5,1);
ObjectCreate(0,"line1",OBJ_HLINE,0,0,price1))

if(ObjectFind(0,"line1")>0) price2=NormalizeDouble(ObjectGetDouble(0,"line1",OBJPROP_PRICE,1),Digits());
Pricebuffer[i] = price2;


}

I am not going to address the many errors in your code, you need to sort them yourself.

You are not actually using any object. For some reason you create an object in the current chart using iClose(), then you get the value from the object! (incidentally the code fails because an object can only be created once)

Why not just use iClose() ??

See the lines commented out and the replacement last line.

   int total = SymbolsTotal(true);
   double price1,price2,PriceBuffer[];
   for(int i=0; i<total; i++)
     {
      string sym = SymbolName(i,true);
      ArrayResize(PriceBuffer,total);
      ArraySetAsSeries(PriceBuffer,true);
      //price1 = iClose(sym,PERIOD_M5,1);
      //ObjectCreate(0,"line1",OBJ_HLINE,0,0,price1);

      //if(ObjectFind(0,"line1")>0)
      //   price2=NormalizeDouble(ObjectGetDouble(0,"line1",OBJPROP_PRICE,1),Digits());
      //PriceBuffer[i] = price2;
      PriceBuffer[i] = iClose(sym,PERIOD_M5,1);
     }
