[amibroker] Scan automatically add symbols to watchlist if...

["supistarde" <supistarde@xxxxxxxx>]

Hi,

I would like to add symbols automatically to my watchlist if they
havbe a higher volatility.
This is my wrong setup:

Filter=C>0;
Buy=0;
per=20;//Set your time period
Graph0 = StDev(log(C/Ref(C,-1)),per)*sqrt(250)*100;
ret=StDev(log(C/Ref(C,-1)),per)*sqrt(250)*100;//
<=StDev(log(C/Ref(C,-1)),pds)*sqrt(250)*120;

IIf(ret-MA(ret,200)*1.3>0,CategoryAddSymbol("",categoryWatchlist,1),CategoryRemoveSymbol("",categoryWatchlist,1)
);
AddColumn(ret,"STDAbw");
AddColumn(Ref(ret,-200)*1.3, "StdAbw*1,3 -200T");
AddColumn(ret-Ref(raus,-200)*1.3, "diff");

If I use only the add function, all symbols in my database are
entered. If I use this setup the watchlist would be empty.
Can someone help me?

Regards,

supi
