An interesting side effect of
http://groups.yahoo.com/group/amibroker/message/40042
is that we may calculate MeanIndicators without AddToComposite() use.
It is obvious from
H1=H;L1=L;C1=C;
N0="^NDX";H=Foreign(N0,"H");L=Foreign(N0,"L");C=Foreign(N0,"C");
StochD0=StochD();
N1="MSFT";H=Foreign(N1,"H");L=Foreign(N1,"L");C=Foreign(N1,"C");
StochD1=StochD();
N2="INTC";H=Foreign(N2,"H");L=Foreign(N2,"L");C=Foreign(N2,"C");
StochD2=StochD();
H=H1;L=L1;C=C1;
MeanStochD=(StochD0+StochD1+StochD2)/3;
we may have the MeanStochD of a database as a daily function, updated
with the new EOD without scan the database.
The great advantage is in intraday use, if you ever run 10 or 20
times/session the AddToComposite() formula to see
is the MeanIndicator crosses the critical level or not.
The same idea may be applied to
http://groups.yahoo.com/group/amibroker/message/40045
expressed with the most recent amibroker function() property :
/* WRITE ONCE */
function ForeignADX( symbol, period )
{
/* save original price arrays */
SC = C;
SO = O;
SH = H;
SL = L;
C = Foreign( symbol, "C" );
H = Foreign( symbol, "H" );
L = Foreign( symbol, "L" );
O = Foreign( symbol, "O" );
Result = ADX( period ); // REPLACE THIS BY ANY AFL FUNCTION
/* restore original arrays */
C = SC;
O = SO;
H = SH;
L = SL;
return Result;
}
/* USE MANY TIMES */
ADX0=ForeignADX( "MSFT", 14 );
ADX1=ForeignADX( "IBM", 14 );
ADX2=ForeignADX( "AAPL", 14 );
MeanADX=(ADX0+ADX1+ADX2)/3;
