The trick is to just write the text once, for example when currentbar=1
or when you draw a new trendline, and then use the text_setlocation and
text_setstring commands to modify it bar by bar. Use the function wizard
and the online help to help keep the syntax straight. Here's an example
indicator that plots an xaverage along with text.....

var: av(0), txt_str(""), txt(0);

av = xaverage(c,10);
txt_str = numtostr(av,2);

if currentbar = 1 then begin
  txt = text_new(date,time,av+1,txt_str);
  text_setstyle(txt,1,1);
  text_setcolor(txt,tool_green);
end else begin
  text_setlocation(txt,date,time,av+1);
  text_setstring(txt,txt_str);
end;

plot1(av,"Average");
