Something like this ought to do it:

If DayOfWeek(Date) = 5 THEN Begin
Value1=Highest(High,5);
Value2=Lowest(Low,5);
Value3=(Value1+Value2)/2;

{begin trendlines}

Value10=TL_New(Date[4],Sess1EndTime,Value1,Date,Sess1EndTime,Value1);
Value11=TL_New(Date[4],Sess1EndTime,Value2,Date,Sess1EndTime,Value2);
Value12=TL_New(Date[4],Sess1EndTime,Value1,Date[4],Sess1EndTime,Value2);
Value13=TL_New(Date,Sess1EndTime,Value1,Date,Sess1EndTime,Value2);
Value14=TL_New(Date[4],Sess1EndTime,Value3,Date,Sess1EndTime,Value3);

End;

If you want only one box on the screen at any time, insert the following
code right under the "{begin trendlines}":

Value20=TL_Delete(Value10);
Value20=TL_Delete(Value11);
.... etc.

You can change the colors of the lines by using the TL_SetColor Statement.
Put this statement in right after you create the lines.  See EL help.
