Re: Drawing lines automatically on charts

["RB" <rhodes@xxxxxxxxxxxxxx>]

I would like to do something similar but with a moving average.
 I would like to have some code that will draw a straight line xbars into
the future or plot Xbars into the future from the, last value of a moving
average using the slope or angle of the moving average value now (0 bars
ago) compared to the moving average value xbars ago.
 Like if the moving average today is lower than yesterday the plot into the
future would be drawn down the same angle or slope of the moving average
drop from yesterday to today.   And plot into the future xbars.

  Any ideas?

 Thanks,

Try the code below for semi-automatically (input: dys) extending a
TL_New(....) line drawn on a daily chart.

The difficulty here is the mixing of dates (used in drawing TL_New(.))
and barnumbers (in TLValue (which finds the price at the end of the
extension)). What is the date of, say 8 bars ahead (the bar you want to
extend to)?

And to do this in a minute chart is more complex due to the mixing of
days and minutes on the time scale.

This extension  of a TL_New(.) is done in Linear Regression Lines (see
the PE code for LinearRegValue (TargetB)). There, only bars are used for
the extension.

input: start(1021001), ends(1021010),p1(l-1), p2(h+1),dys(8);
var:TL(0),bn1(0),bn2(0), TLValuee(0), Tbar(dys),cnt(-1);
array:bbn[1000](0);
array:dday[1000](0);

if d>=ends  then begin
cnt=cnt+1;
bbn[cnt]=barnumber;
dday[cnt]=d;

end;
if d= start  then
BN1=barnumber;
if d=ends  then begin
BN2=barnumber;
If bn2 - bn1 <> 0 Then
TLValuee = (P1 - P2) / (bn2 - bn1) * (bn1 -(bn2+ TBar)) + P1 ;
TL = TL_New(start,1600,p1, ends,1600,p2 );
  TL_SetStyle(TL, 1);
TL_SetColor(TL, blue);
end;
if currentbar=bbn[dys] then TL_SetEnd(TL,dday[dys] ,1600 , TLValuee);
