Thomas,

I tried your codes. They work here. I put them each in their own pane. No problem. I then went to a tab with 1 chart on it and dragged each of your indicators onto that chart. They both display. Chart is still good. Both indicators show up. No error messages.

I was having weird chart problems just yesterday. I would double click one of the standard charts and it would install one of my custom charts. The really weird thing was, when you would Edit Formula it would be the formula for the standard chart! (even though it displayed my custom code of > 400 lines of code, editor showed only 10 lines of standard code). I reinstalled all from backups and re-upgraded to 4.70. Seems OK now.

Hi Herman!

  
Perhaps the indicators should be named differently in your workspace?
    

They are (T3 and Adaptive T3), so this should not be the cause for this
problem.

  
Just guessing...
    

Herman, could you - or somebody else - try out if the same problem occurs
for you? If yes, it would be a AB bug. If no, my AB installation probably
flipped.;-)

Greetings, Thomas

  Hi!

  I experienced a very strange problem with two formulas. One is the T3
  moving average - the formula is essentially the one Jayson presented in
the
  AB library:

  function T3(price,periods)
  {
  s = Param("s",0.8,0.2,2,0.1);
  e1=EMA(price,periods);
  e2=EMA(e1,Periods);
  e3=EMA(e2,Periods);
  e4=EMA(e3,Periods);
  e5=EMA(e4,Periods);
  e6=EMA(e5,Periods);
  c1=-s*s*s;
  c2=3*s*s+3*s*s*s;
  c3=-6*s*s-3*s-3*s*s*s;
  c4=1+3*s+s*s*s+3*s*s;
  Ti3=c1*e6+c2*e5+c3*e4+c4*e3;
  return ti3;
  }

  P = ParamField("Price field",-1);
  Periods = Param("Periods", 15, 2, 200, 1 );
  //Plot(C,"",4,64);
  //Plot(T3(p,periods),"T3",colorYellow,1);
  Plot(t3(p,periods),_DEFAULT_NAME(), ParamColor( "Color", colorCycle ),
  ParamStyle("Style") );

  The other one is the Adaptive T3 (introduced in S&C 6/2001) where s in the
  above formula is replaced by the R-squared over a specified period:

  P = ParamField("Price field",-1);
  Periods = Param("Periods", 15, 2, 200, 1 );
  Corrperiods=Param("R-squared periods",10,5,50,1);
  s = (Correlation(Cum( 1 ),p,corrperiods))^2;
  e1=EMA(p,periods);
  e2=EMA(e1,Periods);
  e3=EMA(e2,Periods);
  e4=EMA(e3,Periods);
  e5=EMA(e4,Periods);
  e6=EMA(e5,Periods);
  c1=-s*s*s;
  c2=3*s*s+3*s*s*s;
  c3=-6*s*s-3*s-3*s*s*s;
  c4=1+3*s+s*s*s+3*s*s;
  aT3=c1*e6+c2*e5+c3*e4+c4*e3;
  Plot(at3,_DEFAULT_NAME(), ParamColor( "Color", colorCycle ),
  ParamStyle("Style") );

  Now my problem: If I drag either of these indicators onto a chart in one
  pane and the other one onto a, say, indicator in another pane everything
is
  okay. BUT: If I drag BOTH indicators onto a chart in the SAME pane the
  chart vanishes and the pane becomes empty with the exception of an error
  message in the upper left corner - see the attached JPG. If I delete one
of
  these two indicators everything is okay again.

  Again: This only happens if BOTH indicators are dragged into ONE pane.

  Does anybody have an explanation for this strange behavior of AB?

  Greetings, Thomas
