# 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](/en/docs/constants/errorswarnings/errorcodes) details use the [GetLastError()](/en/docs/check/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](/en/docs/constants/chartconstants/enum_chart_property#enum_chart_property_integer) property using the [ChartGetInteger()](/en/docs/chart_operations/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);
|
||
}
|
||
/*
|
||
result:
|
||
Chart ID 133246248352168439, subwindow 0. Attached indicators: 3
|
||
Chart ID 133246248352168439, subwindow 1. Attached indicators: 2
|
||
Chart ID 133246248352168439, subwindow 2. Attached indicators: 1
