Quick question about "StringConcatenate"

New comment
 

Hi All. Quick question about this indicator, it shows RSI value on chart window in 6 digits format, what do I have to change or add to make it show only 2 first digits?

------------------------------------------------

#property indicator_chart_window

extern int Periods=14;
extern int Price=PRICE_CLOSE;
extern int Shift=0;

int init()
  {
      if(ObjectFind("M4X - RSI")!=0)
          {
              ObjectCreate("M4X - RSI",OBJ_LABEL,0,0,0,0,0);
              ObjectSet("M4X - RSI",OBJPROP_XDISTANCE,260);
              ObjectSet("M4X - RSI",OBJPROP_YDISTANCE,1);
          }
      if(ObjectFind("M4X - RSI")==0)
          {
                string sVal=StringConcatenate(dRSI ());
                if(dRSI()>50 && dRSI()<=70)
                    {
                        ObjectSetText("M4X - RSI",sVal,8,"Tahoma",Lime);
                    }
                else if(dRSI()<50 && dRSI()>=30)
                    {
                        ObjectSetText("M4X - RSI",sVal,8,"Tahoma",White);
                    }
              else if(dRSI()>70 || dRSI()<30)
                  {
                      ObjectSetText("M4X - RSI",sVal,8,"Tahoma",Gold);
                  }
              else
                  {
                      ObjectSetText("M4X - RSI",sVal,8,"Tahoma",CLR_NONE);
                  }
          }
  }

int deinit()
  {
      ObjectDelete("M4X - RSI");
  }

int start()
  {
        int iIndicatorCounted=IndicatorCounted();
        if(iIndicatorCounted<0)
            {
                return(-1);
            }
        int iLimit=Bars-iIndicatorCounted;
        for(int i=iLimit;i>=0;i--)
            {
                string sVal=StringConcatenate(dRSI());
                if(dRSI()>50 && dRSI()<=70)
                    {
                        ObjectSetText("M4X - RSI",sVal,8,"Tahoma",Lime);
                    }
                else if(dRSI()<50 && dRSI()>=30)
                    {
                        ObjectSetText("M4X - RSI",sVal,8,"Tahoma",White);
                    }
              else if(dRSI()>70 || dRSI()<30)
                  {
                      ObjectSetText("M4X - RSI",sVal,8,"Tahoma",Gold);
                  }
              else
                  {
                      ObjectSetText("M4X - RSI",sVal,8,"Tahoma",CLR_NONE);
                  }
            }
  }

double dRSI()
    {
        return(iRSI(NULL,0,Periods,Price,Shift));
    }

Hi,

Use this:  NormalizeDouble();

Thank you and apologize, I'm new in this, still learning ;)

Hi,

Thank you it worked :)
I've got one more question I'm new in this stuff, can you have a look and tell me if I've done it the long way around? or is there an easier way to do it?

Thank you it makes things more clear.
I wanna ask you something else. I'm using script to hide all the drawings from the chart (fibo, sup. res. etc.) but it also hides the indicator that you've help me with (and I don't want that) but it leaves different one that I've also have on the chart. I've tried to compare both indicators to find some code which prevent one indicator from being hide but no luck and I'm stuck.
Can you help?
