This synopsis has been put together from a few posts about the Bands of volume - their definitions and illustrating the vertical way to view how a trend progresses. Thanks to Doaks and NCX for extracting this information and to Mr. Hershey for providing it.Quote from jack hershey:SNIP
In trend monitoring and analysis (as opposed to trend following which does not work), a trader has a context for what he is doing. In a channel the first trend move begins in the old channel, then breaks out of the old channel and goes to the point that sets up the point 2 of the new channel.
When P1 and T1 are established the trend can continue. The trend has a defined range in the independent variable. I call this range 'A' BAND. This is a volume "context" for the trend.
In the independent variable this has a direct correspondence to a volume range established by the range of volume during that price traverse. T1 is measured mathematically relative to the assigned P1 that began the trend. T1 occurs as trend overlap ends. I put a box on the volume bar that sets the lower range limit. The box is T1. I note the volume in the log. This makes me keep aware of T1 and think about the trend as the trend moves forward in the market. Subsequently this range diminishes as the trend continues to move forward.
As point 3 of the channel is set, then the volume range is different. 'B' BAND has come into being. B band measures the second non-dominant leg of the trend. It is between P2 and T2P volume values.
'C' BAND comes after the blue ray for T2F is set. It is a band between the red and blue rays (a range between T2P and T2F). It is fairly narrow.
These values can be used to define how trends come to their natural ends.
Even with this information, I'm still not clear with regard to the EEs, Ba and Ca - the Band Passes.
1. Are these EEs noted when the 'B' BAND and 'C' BAND come into play?
2. Are they noted when a new bar is outside the range previously set as the high or low range for the trend, i.e. - surpassed the range set by the primary, the A BAND?
i've included an attachment provided in a different thread for reference purposes.
