MQL5 ReferenceChart OperationsChartIndicatorGet 


Returns the handle of the indicator with the specified short name in the specified chart window.

int  ChartIndicatorGet(
   long           chart_id,              // Chart ID
   int            sub_window             // The number of the subwindow
   const string   indicator_shortname    // Short name of the indicator



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


[in]  The number of the chart subwindow. 0 means the main chart window.

const indicator_shortname

[in]  The short name if the indicator, which is set in the INDICATOR_SHORTNAME property using the IndicatorSetString() function. To get the short name of an indicator, use the ChartIndicatorName() function.

Return Value

Returns an indicator handle if successful, otherwise returns INVALID_HANDLE. To get information about the error, call the GetLastError() function.


When creating an indicator, be careful forming its short name, which is written in the INDICATOR_SHORTNAME property using the IndicatorSetString() function. It is recommended that a short name should contain the values of input parameters of the indicator, since the indicator is identified in the ChartIndicatorGet() function based on its short name.

Another way to identify the indicator is to get a list of its parameters for a given handle using the IndicatorParameters() function and then to analyze the obtained values.
