# OBJ_ARROW_STOP Stop sign. ![Note](pics/objarrowstop.png) Note Anchor point position relative to the sign can be selected from [ENUM_ARROW_ANCHOR](/en/docs/constants/objectconstants/enum_anchorpoint#enum_arrow_anchor) enumeration. Large signs (more than 5) can only be created by setting the appropriate [OBJPROP_WIDTH](/en/docs/constants/objectconstants/enum_object_property#enum_object_property_integer) property value when writing a code in MetaEditor. Example The following script creates and moves Stop sign on the chart. Special functions have been developed to create and change graphical object's properties. You can use these functions "as is" in your own applications. ``` //--- description #property description "Script draws \"Stop\" sign." #property description "Anchor point coordinate is set in" #property description "percentage of the chart window size." //--- display window of the input parameters during the script's launch #property script_show_inputs //--- input parameters of the script input string            InpName="ArrowStop";     // Sign name input int               InpDate=10;              // Anchor point date in % input int               InpPrice=50;             // Anchor point price in % input ENUM_ARROW_ANCHOR InpAnchor=ANCHOR_BOTTOM; // Anchor type input color             InpColor=clrRed;         // Sign color input ENUM_LINE_STYLE   InpStyle=STYLE_DOT;      // Border line style input int               InpWidth=5;              // Sign size input bool              InpBack=false;           // Background sign input bool              InpSelection=false;      // Highlight to move input bool              InpHidden=true;          // Hidden in the object list input long              InpZOrder=0;             // Priority for mouse click //+------------------------------------------------------------------+ //| Create Stop sign                                                 | //+------------------------------------------------------------------+ bool ArrowStopCreate(const long              chart_ID=0,           // chart's ID                      const string            name="ArrowStop",     // sign name                      const int               sub_window=0,         // subwindow index                      datetime                time=0,               // anchor point time                      double                  price=0,              // anchor point price                      const ENUM_ARROW_ANCHOR anchor=ANCHOR_BOTTOM, // anchor type                      const color             clr=clrRed,           // sign color                      const ENUM_LINE_STYLE   style=STYLE_SOLID,    // border line style                      const int               width=3,              // sign size                      const bool              back=false,           // in the background                      const bool              selection=true,       // highlight to move                      const bool              hidden=true,          // hidden in the object list                      const long              z_order=0)            // priority for mouse click   { //--- set anchor point coordinates if they are not set    ChangeArrowEmptyPoint(time,price);
