I am trying to create a rectangle in main chart with following mql5 codes. Nothing created. what is wrong? Thanks in advance. void OnTick() { // ObjectDelete(_Symbol,"Rectangle"); ObjectCreate ( _Symbol, "Rectangle", OBJ_RECTANGLE, 0, 0, 0, 1500, 1500 ); // Print ("Test"); ObjectSetInteger(0,"Rectangle", OBJPROP_COLOR,clrAliceBlue); ObjectSetInteger(0,"Rectangle", OBJPROP_FILL,clrDarkSlateBlue); } //+------------------------------------------------------------------+
