Hello, I have always many interest in ranking and stocks selection.
I think you can add in watchlist 0 thousand stocks, and get for each
stock its monthly rank ( with full code below)
so you can Buy = conditions and (Monthly_rank < 101) ;
I have tested the code in AA with status (stocknum) and it works.
stephane
listNum=0 ;//enter watchlist number
list = GetCategorySymbols( categoryWatchlist, listnum );
TimeFrameSet( inMonthly );
for( i = 0; ( sym = StrExtract( list, i ) ) != ""; i++ )
{
SetForeign(sym);
VarSet("MyInd"+i,MFI(14));// Indicator
/*
VarSet stores the Value of MFI
ticker 0 has its value of MFI stored in MyInd + 0
ticker 1 has its value of MFI stored in MyInf + 1 ...
*/
Rank =1;// Initialize the Rank
for( j = 0; ( item = StrExtract( list, j ) ) != ""; j++ )
{
SetForeign(item);
VarSet("ThisInd"+j,MFI(14));//Indicator
Rank=Rank + IIf( VarGet("MyInd"+i) < VarGet("ThisInd"+j),1,0);
/*
VarGet returns the value of VarSet
Every value of MyInd + i is compared to every Value of ThisInd + j
and the Rank in incremented of + 1 every time the Ind is < to others.
*/
RestorePriceArrays();// to get out the influence of SetForeign
}
VarSet("Rank"+i,Rank);
}
TimeFrameRestore();
Filter=1;//Status("lastbarinrange");
Count=Status("stocknum");
Var=IIf(InWatchList(0),VarGet("Rank"+ Count),Null);
AddColumn(TimeFrameExpand(Var , inMonthly),"Monthly Rank");
AddColumn(Var,"Daily Rank");
//Plot(TimeFrameExpand(Var , inMonthly),"",2,1);
