The low of the current bar is in. Volume pace might be increasing, don't quite know yet. However we do see that current price after this bar is heading toward a decision point on 9/23 with the convergence of the short and long. If this bar's current volume surpasses the previous bar we know that the current long trend has reasserted itself.
How to you come to that conclusion ... and why would you? Rather see if it does and not have a bias in place.
Observing the current PV relationship, on 9/18 that Dominant bar of +P and +V set a zone for a Lateral by the following two bars are within it both in price and volume.
Since the Market's System of Operation is event based and cyclic, ebbing and flowing like the tide or a heartbeat, what we know about a current observation of decreasing volume is that volume will increase sometime in the future. It could continue decreasing, whereas one is a signal of change and the latter a sign of continuation. This previous statement can lead to confusion when "fractal jumping" occurs. For continuation at one fractal can be change on the fractal above/below.
Volume alone isn't the indicator, it's the relationship between volume as the independent variable determining price as the dependent variable. Looking at a current bar building, we don't know until EOB if the accumulated volume increased or decreased from the bar before. We can if we go to faster timescales or by creating tooling to observe the current bar's volume pace - the rate by which transactions are accumulating. This rate and direction fluctuates within each current bar.
We do know that the Intermediate long trend has lost it's initial momentum by it's XO of the RTL. It can establish a new pt3 for a new lower sloped trend. The current bar is currently in a non-Dominant move. We see this by -V.
We are also at a moment of a larger timeframe area of congestion, convergence and centering.
I don't know if it's possible to not have a bias. However, I do know that it is possible to understand the bias we have.
We can balance the bias in both directions by mocking up possible collaborating/competing scenarios and what must come into being as those scenarios unfold. This is the distinction between anticipating and predicting. The first is dynamic, the second is static. This mock-up is facilitated by IF, THEN statements.
When a bar first opens, it's possibilities are great but as it come to EOB, those paths reduce to the path of least resistance, to it's finite and precise close.
