The script removes from the current chart all objects of the type selected by the trader in input parameters.

//+-----------------------------------------------+
//|  SCRIPT INPUT PARAMETERS                      |
//+-----------------------------------------------+
input ENUM_OBJECT OBJ_TYPE = -1;    //The type of objects to delete

When used with default parameters, the script deletes all objects from the current chart.

If you regularly need to delete objects of a fixed type, you should write a copy of the script with the appropriate object type ID specified as an input variable. For example, here is a script for removing trend lines ToClearChartObjectsByOBJ_TREND:

//+-----------------------------------------------+
//|  SCRIPT INPUT PARAMETERS                      |
//+-----------------------------------------------+
ENUM_OBJECT OBJ_TYPE = OBJ_TREND;    //The type of objects to delete
