[amibroker] Dynamic Window Title for a Composite

["Phsst" <phsst@xxxxxxxxx>]

The following is a derivative of some code that Herman posted this
week. This is just an example of one approach to managing dynamic
window Titles.

This approach allows you to use:

  * One (1) generic Composite containing 'Counts' for different
Explores and different metrics

and

  * One (1) generic IB AFL with dynamic Titles for display purposes

and

  * Many Explores that generate various counts and Titles for use with
the generic IB 

Make many different Explorations to count various metrics, changing
the Title stored in the CompositeDescription variable, and then after
each execution, the IB Title dynamically changes to the value written
to the file "afl\\StatCountsTitle.txt"


The Explore:

// -------EXPLORATION--------
// StatCounts - Number of stocks making new highs
// Use IB 'StatCounts - Display Composite' to View results
// Explore w N last days = 1 against desired watchlist

CompositeDescription = "New Highs / Lows";

fh = fopen( "afl\\StatCountsTitle.txt", "w");
if( fh )
{
   fputs( CompositeDescription + " ", fh ); 
}
fclose( fh ); 
 
SetOption("NoDefaultColumns",False);
New10DayHigh = H>Ref(H,-10);
CloseUp3 = C>1.03*Ref(C,-1);
VolumeUp = V>Ref(V,-1);
ConditionHigh = New10DayHigh AND CloseUp3 AND VolumeUp;

New10DayLow = L<Ref(L,-10);
CloseDn3 = C< 0.97*Ref(C,-1);
VolumeDn = V<Ref(V,-1);
ConditionLow = New10DayLow AND CloseDn3 AND VolumeDn;

Filter = ConditionHigh OR ConditionLow;
AddToComposite(ConditionHigh,"~StatCounts","H",1|2|4|16);
AddToComposite(ConditionLow,"~StatCounts","L",1|2|4|16);
AddColumn(ROC(H,10),"%10DayHi",1.2);
AddColumn(ROC(V,1),"%Vup",1.2);
AddColumn(ROC(C,1),"%Cup",1.2);
// ----------- END OF EXPLORATION ----------

... AND NOW ... The generic IB AFL with dynamic Title:

// -------IB DISPLAY OF COMPOSITE --------
// StatCounts - IB Display Composite Indicator

fh = fopen( "afl\\StatCountsTitle.txt", "r");
if( fh )
{
  CompositeDescription =  fgets( fh ); 
}
fclose( fh ); 

SetForeign("~StatCounts", True, True);

Title = "~StatCounts Composite - " + CompositeDescription

Plot(H,"H",colorBrightGreen,styleLine | styleThick);
Plot(L,"L",colorRed,styleLine | styleThick);

RestorePriceArrays();
//---------- END OF IB CODE ----------

My "Title =" code was more complex, but I simplified it to avoid line
wrap problems.

Hope this is useful to someone.
