Use the MQL4 "Object Functions" ( Ref. to GUI Objects' manipulations )

Among many graphical elements, MetaTrader Terminal 4 can place also the few of Fibonacci based technical indicators ( let's go ahead with the Fibonacci retracement tool, other are similar in the use and can apply the same to them ).

First, one has to create such object, using:

ObjectCreate( chart_ID,                           // ref. doc
              anInterimObjNAME,                   //      a name to be used
              OBJ_FIBO,                           //      a type of GUI-obj to draw
              0,                                  //      sub-window
              time1, price1,                      //      where to start
              time2, price2                       //      where to finish
              );

Next, one can adapt many attributes of the already created object - colour, line-type / line-thickness, texts and also the starting time, starting price, ending time, ending price - to such values that are pleasing one's taste.

//--- set how many levels you want to paint
      ObjectSetInteger( chart_ID,
                        anInterimObjNAME,
                        OBJPROP_LEVELS,
                        levels
                        );

//--- set the properties of each of the level
   for (  int i = 0; i <  levels; i++ )
   {      ObjectSetDouble(  chart_ID, anInterimObjNAME, OBJPROP_LEVELVALUE, i, values[i] ); // level value
          ObjectSetInteger( chart_ID, anInterimObjNAME, OBJPROP_LEVELCOLOR, i, colors[i] ); // level color
          ObjectSetInteger( chart_ID, anInterimObjNAME, OBJPROP_LEVELSTYLE, i, styles[i] ); // level style
          ObjectSetInteger( chart_ID, anInterimObjNAME, OBJPROP_LEVELWIDTH, i, widths[i] ); // level width
          ObjectSetString(  chart_ID, anInterimObjNAME, OBJPROP_LEVELTEXT,  i, DoubleToString( 100 * values[i], 1 ) ); // level description
          }
