Congratulations Frank. You have achieved a first. The only Google search result for "auction trend" and "market profile" yielded this one and only URL:
http://www.google.com/search?hl=en&r...ket+profile%22
which is this thread.
What is auction trend? aside from your current description of 'value placement'? Is it Market Profile based? Could you share a more specific description of your indicator? Thanks.
