MQL5 ReferenceChart OperationsChartIndicatorsTotal

ChartIndicatorsTotal

Returns the number of all indicators applied to the specified chart window.

int  ChartIndicatorsTotal(
   long  chart_id,      // chart id
   int   sub_window     // number of the subwindow
   );

Parameters

chart_id

[in] Chart ID. 0 denotes the current chart.

sub_window

[in] Number of the chart subwindow. 0 denotes the main chart subwindow.

Return Value

The number of indicators in the specified chart window. To get error details use the GetLastError() function.

Note

The function allows going searching through all the indicators attached to the chart. The number of all the windows of the chart can be obtained from the CHART_WINDOWS_TOTAL property using the ChartGetInteger() function.

Example:

//+------------------------------------------------------------------+
//| Script program start function                                    |
//+------------------------------------------------------------------+
void OnStart()
  {
//--- get the current chart ID and the number of its subwindows, including the main window
   long chart_id = ChartID();
   int  wnd_total= (int)ChartGetInteger(0,CHART_WINDOWS_TOTAL);

//--- iterate over all current chart windows in a loop
   for(int w=0; w<wnd_total; w++)
     {
      //--- get the number of indicators attached to the chart window specified by the loop index
      int ind_total=ChartIndicatorsTotal(chart_id, w);

      //--- get the number of indicators attached to the specified chart window
      PrintFormat("Chart ID %I64d, subwindow %d. Attached indicators: %d", chart_id, w, ind_total);
     }
