afl's

["David Holzgrefe" <dtholz@xxxx>]

Hi all L am playing with and afl and wanted the 
sell signal to be generated
if the close was equal to or lower  bar of the 
buy signal ?
 
no luck yet,  so I thought I would ask some 
the more accomplished coders if the could see a way ...
 
 
thanks David

cond1= o > ma( close, 21) and ref( cross( o, ma( 
close, 21 ) ), -1 )OR l > ma( close, 21) and ref( cross( l, ma( close, 21 
) ), -1 )OR c > ma( close, 21) and ref( cross(c, ma( close, 21 ) ), -1 
)OR h > ma( close, 21) and ref( cross( h, ma( close, 21 ) ), -1 
);
 
ticksize = .01;
 
 
 
sign = cond1 AND  close > 10 * ticksize + 
ref( close, -1 );buy = sign;
 
sellsign=sign;  ??sell =  
sign;   ???
