iCustom problem

[Walter919]

Hello, I have a strange problem. When I load my written indicator based on another iCustom indicator on the chart, two lines appear, although it should be only one.

#property strict

#property indicator_chart_window
#property indicator_buffers 2
#property indicator_color1 clrYellow
#property indicator_color2 clrAqua

input int SignalPeriod=5;
input int NR_SLIPE=3;
input double FilterNumber=1.0;
input int Points=20;

double Above[],Below[],temp[];
//+------------------------------------------------------------------+
//| Custom indicator initialization function                         |
//+------------------------------------------------------------------+
int OnInit()
{
   IndicatorBuffers(3);

   SetIndexBuffer(0,Above);
   SetIndexBuffer(1,Below);
   SetIndexBuffer(2,temp);
   SetIndexStyle(0,DRAW_LINE,STYLE_SOLID,3);
   SetIndexStyle(1,DRAW_LINE,STYLE_SOLID,3);
   SetIndexStyle(2,DRAW_NONE);
   SetIndexLabel(0,"Above");
   SetIndexLabel(1,"Below");
   
   return(INIT_SUCCEEDED);
}

I know that it is not obvious, but topics concerning MT4 and MQL4 have their own section.

In future please post in the correct section.

I will move your topic to the MQL4 and Metatrader 4 section.
