Subject: Re: [amibroker] Values "Offset" in Loop Output
as RUT is first (0) you get the DJ results in the explore as expected From
observation exploration always default sorts the results automatically in
symbol name() alpha order. You can change the sorting of explore uisng
SetSortColumns( col1, col2, .... )
