What causes failure to view buffer on chart window after declaring it. Or better still how can I view buffer data on indicator chart window. My indicator won't show me the buffers

[Marco vd Heijden]

Do you have any code so far ?

1. You don't "declare" buffers. You declare a double array and in OnInit, make it a buffer:

   double b[];
   :
      SetIndexBuffer(0, b);

2. In MT4 since build 1090 tell it the buffer type. (It no longer defaults to line.)
   

   #property   indicator_type1   DRAW_LINE                  // Bug 1090 must set.
   

   alternatively in OnInit()

   SetIndexStyle(0, DRAW_LINE);
