Simple Average Daily Range Indicator

#1 Postby Lonesome » Sun Jan 15, 2017 9:21 am

Below is the script for a simple Average Daily Range Indicator.
This Indicator works only in the 1day TimeFrame.
It creates a line graph in its own window. The ADR is given in pips.
The Indicator can distinguish between Yen contains pairs and pairs not containing Yen.

Code: Select all

//---------------------------------------------------------------------------
// Average Daily Range
//
// The Indicator works only in the 1 day TimeFrame
// The Indicator calculates pips
// The Indicator can distinguish between Yen pairs and non-Yen pairs
//---------------------------------------------------------------------------
library AverageDailyRange;

uses
  SysUtils,
  Math,
  Graphics,
  IndicatorInterfaceUnit,
  TechnicalFunctions;

var
  // External variables
  Period: integer;

  // Buffers
  ADRBuffer: TIndexBuffer;
  TempBuffer: TIndexBuffer;

//---------------------------------------------------------------------------
// Initialize indicator
//---------------------------------------------------------------------------
procedure Init; stdcall;
begin
  // define properties
  IndicatorShortName('Average Daily Range (ADR)');
  SetOutputWindow(ow_SeparateWindow);

  // register options
  AddSeparator('Common:  this Indicator works only in the 1 day TimeFrame');

  RegOption('Period', ot_Integer, Period);
  SetOptionRange('Period', 1, MaxInt);
  Period := 14;

  // create buffers
  ADRBuffer := CreateIndexBuffer;
  TempBuffer := CreateIndexBuffer;

  IndicatorBuffers(1);
  SetIndexBuffer(0, ADRBuffer);
  SetIndexStyle(0, ds_Line, psSolid, 3, clLime);
  SetIndexLabel(0, 'Pips');
  IndicatorDigits(2);
end;

//---------------------------------------------------------------------------
// Deinitialize indicator
//---------------------------------------------------------------------------
procedure Done; stdcall;
begin

end;

//---------------------------------------------------------------------------
// Calculate requested bar
//---------------------------------------------------------------------------
procedure Calculate(index: integer); stdcall;
var
  i, Position, Multiplier: integer;
  P_High, P_Low, sum: double;

begin

  if Timeframe <> 1440 then exit;

  Position := AnsiPos('JPY', Symbol);

  if Position <> 0
  then Multiplier := 100
  else Multiplier := 10000;

  P_High := High(index);
  P_Low := Low(index);
  TempBuffer[index] := P_High - P_Low;

  sum:=0;
  for i:=0 to Period - 1 do
    sum := sum + TempBuffer[index + i];
  ADRBuffer[index] := (sum/Period)*Multiplier;

end;

exports

  Init, Done, Calculate;

end.
