What is the EMA period?
 
moving average exp. period. can I throw it in here, can someone tweak it?

I just want to use it on different pairs, but it is designed for EURUSD, so I can't manually adjust it, neither morally, nor physically

 
both opening and closing on sliding
 
can anyone help?
 

Good morning !

Could you please tell me how to output two calculated parameters from a function calculation ? If I understand correctly - the return() function returns only one parameter specified in its brackets.

double РасчётТЛвверх(int a, double Цена1 Син)
        {
          double МА23 = iMA(NULL,0,23,0,MODE_EMA,PRICE_CLOSE,a),
                 
                 MМА23[17];
                 
                 MМА23[0]=МА23-603*Point;
                 MМА23[1]=МА23-377*Point;
                 MМА23[2]=МА23-233*Point;
                 MМА23[3]=МА23-144*Point;
                 MМА23[4]=МА23-89*Point;
                 MМА23[5]=МА23-55*Point;
                 MМА23[6]=МА23-34*Point;
                 MМА23[7]=МА23-21*Point;
                 MМА23[8]=МА23;
                 MМА23[9]=МА23+21*Point;
                 MМА23[10]=МА23+34*Point;
                 MМА23[11]=МА23+55*Point;
                 MМА23[12]=МА23+89*Point;
                 MМА23[13]=МА23+144*Point;
                 MМА23[14]=МА23+233*Point;
                 MМА23[15]=МА23+377*Point;
                 MМА23[16]=МА23+603*Point;
  
          for(int i=0;i<=16;i++)
            {
              if(NormalizeDouble(Цена1 Син+8*Point,Digits)<=NormalizeDouble(MМА23[i],Digits))
                {
                  double ТЛвверх=MМА23[i+5];
                  double БезУбMМА23 вверх = MМА23[i+4];
                  break;
                    
                      
                }
            }
         
          
                
         return(ТЛвверх);

I can output only TLvup. And I also want to use BezubMMA23up. But if I write so - return(TLup, BezUbMMA23up) or return(TLup; BezUbMMA23up), I get an error. The function is called as double TL-up=CalculateTL-up(a,Price1Cin);

How to call to use both TLup and BezUbMMA23up ? Or for calculation of parameter WithoutMMA23up I should separately write the given code again and output return( WithoutMMA23up) ?

 
For example, make a global Variable and insert the result of the function there...
 
So you still need to output two results from the calculation. The attached code only outputs one. How can I output two?
 
Thank you all, found the answer here - https://www.mql5.com/ru/articles/1496
