B3 Directional Trend Index ~ All about the trend! William Blau is the designer of this gem, and IMHO it is the best trend finder of all the lagging indicators out there I have tested. It is important to pay attention to the slope and thickness of the line, and its relationship to zero. A reversion to the zero may look momentous, but in fact it could reverse when it reaches mean, only to turn back around. You can see this in March and April of this silver futures . Makes for a great instrument on anything you consider trendy, like crude oil for example. The default user inputs are set to my liking, as I find them to be great on all charts and resolutions. You may read around to find more about this on the internet, or its mentioned in Krausz's work. Also, imprtant to remember when no trend, trend finders like this sufffer, so be wise as to what market condition you are in. Rangy and within Range = no, On the Move = yes.
