Hi i'm not sure i understand what you mean.

could you give a better explanation of what you posted below.   


""simultaneously screen for
the stocks whose price penetrates their 20-day SMA (up
or down, either way), and after penetration, never
touch their 20-day again until another positive
penetration."" 





 This exploration is the rsi 20 being greater than 50 >= 20 days,

 when the rsi20 crosses below the 50,
 the close should have been lower than 
an MA(c,20)for 10 or more bars, during 
the period where the rsi(20) was > than 50.


 the plot will show the rsi(20)>50 condition with green outlines on 
the candles.
 a blue outline on the candles no true condition.

 A yellow outline is when cond1 is true. 




RSIx=IIf(RSI(20)>50,1,0);
rsixcount=BarsSince(RSIx==0);
//RSIbars=RSIxcount>=20;

MAz=IIf(C<MA(C,20),1,0);
MAcount=BarsSince(MAz==0);

Cond1=IIf(BarsSince(Ref(rsixcount>=20,-1) AND rsixcount==0)==0 AND 
BarsSince(MAcount==0)>=10,1,0);


Filter=Cond1;
AddColumn(RSIx,"rsix");
AddColumn(RSIxcount,"RSIxcount");
AddColumn(MAz,"MAz");
AddColumn(MAcount,"MAcount");
AddColumn(Cond1,"Cond1");

Plot(C, "",6+Cond1-RSIx,64);
Plot(MA(C,20),"",4 ,4 );
