Hello,
You have bug in your formula.
The "w" variable may be UNDEFINED if it ticker does not match
to any listed symbol.
You have to INITIALIZE 'w' variable in all control paths.
Corrected code follows:
t = Name();
w = 0; // IMPORTANT - initialize it for REMAINING cases !!!
if( t == "C" ) w = 1;
if( t == "KO" ) w = 1;
if( t == "DOW" ) w = 1;
if(t== "EXC" ) w = 1;
if(t== "XOM" ) w = 1;
if(t== "GE" ) w = 1;
if(t== "PFE" ) w = 1;
if(t== "PG" ) w = 1;
if(t== "UPS" ) w = 1;
if(t== "WMT" ) w = 1;
/* AddToComposite statements are for Automatic Analysis -> Scan */
/* add Close price to our index OHLC fields */
AddToComposite(w*C, "~NYSE Wave", "C" );
AddToComposite(w*O, "~NYSE Wave", "O" );
AddToComposite(w*H, "~NYSE Wave", "H" );
AddToComposite(w*L, "~NYSE Wave", "L" );
AddToComposite(w*V, "~NYSE Wave", "V" );
/* add one to open intest field (we use this field as a counter) */
AddToComposite( 1, "~NYSE Wave", "I" );
Buy = 0; // required by scan mode
/* this part is for Indicator Builder */
Graph0 = Foreign( "~NYSE Wave", "C" )/Foreign( "~NYSE Wave", "I" );
