I scalp the Dax mainly and try to use market depth to position my entries and exits. If possible, I position stops behind/within large volume and sometimes position limit entries in front of large volume. I realise that this is an inexact and sometimes unreliable science because of the limit display only, pulling and spoofing etc.. However, I do feel that it has something to offer and think I profit from it in quite a lot of my trades. I have also noticed some patterns in market depth that tend to prodvide support/resistance and to some degree direction. Has anyone else noticed patterns that they use?
