Dimitri,
to optimize on several composites
below is my solution with two steps and I prefer to use 
addtocomposite since a formula with strextract  function returns 
a "pseudo composite" aligned with the youngest stock.

stephane

////////////////////////
//Creation of Multiples composites
/////////////////////
for(Nb=4;Nb<30;Nb++)
{
Comp=IIf(MFI(Nb)>50,1,-1);
AddToComposite(Comp,"~MFI" + WriteVal(Nb,1.0),"X");
Buy=0;
}

////////////////
//BACKTEST and optimization with composites
//////////////////
/**Optimize Trend**/
nb=Optimize("Comp",10,10,50,1);
Comp = Foreign("~MFI" + WriteVal(nb , 1.0 ), "X");
Trend= Comp >0 ;

/**Buy**/
Buy= Cross(CCIa(C,14),100) AND Trend ;
Sell=ExRemSpan(Ref(Buy,-2),2);
