Pierre, thanks very much for some of the last posts with intersting lessons in EL
and TS - good thing that we have solved the Y2k patch problem discussion, with
OR finally coming out of the woods and giving us a rest till next summer.
PO ecrit on some date somewhere in Paris: (free translation from AOLfrench):

Is that a MUST here ?

Can you elaborate about the "need for speed optimization". What happens if not
optimized ? As we all have "powerfull" pcs with lots of rams isnt it simple enough
to be done straight ?.....what happens with LARGE, heavy codes ? Will it delay
the display of the PRICE and the INDICATOR ? Something which allways
bugged me: If I have lots of pages open AND lots of indicators on lots of
different symbols - DO I see everything "5 seconds" or so later than just open a
single QUOTE PAGE ????

1) I plot this a bit different (and thats how I understood the ORIGINAL question)
to see just a NEGATIVE or POSITIVE value better and clearer I plot:
if value1 > 0 then begin <== just plots if its ABOVE or BELOW
Plot1(value1,"+");
end else begin
plot2(value1,"-");
end;
2) isnt MY stuff more difficult to get colours ok ? - its weekend and I cant test
REALTIME :-(((
3) Also Im suprised about using the plot statements twice - havent read that in
OMEGA manual (have I ever read it ? <g>) - is that "common practice" ?
4) THANKS
