Evolving POC & Value Areas query

[cclsys]

I have been using the excellent DValue indicator for some time now and was around when Dean kindly got the POC to update bar-by-bar and stay on the chart that way so it is not a horizontal line across the whole chart and you can compare the current value with the ones before (i.e. it tracks more like a moving average for example).

Is there an update or has someone else written this so you can get the evolving VaT and VaB tracking live the same as the POC? I would really like to see the rolling Value Area as a dynamic band along with the relative POC. There was one by a Cory for 6.5 but it hasn't been updated and there are elements in the coding that don't work. I attach a copy of that in case any programming whizzes here can update it for me.

But really I would like DValue to have this capability...

Hi cclsys,

Hi,

The attached customized indicator in following link can plot developing POC/VAH/VAL. Please let me how you think about it.

Dear qfweiwei:

For some reason I did not get an email about your contribution. I came back to this thread because I just figured it out using DValue as the base (added in DataSeries and two new plots, the RtVAT and RtVAB). Works fine.

Now I will download and check yours out.

Meanwhile, here is my alteration to DValueArea called DValueAsh (Ash is the beginning of my first name).

I have two screenshots. One with the default lines across the entire chart, the second (DVA dynamic) with the new dynamic lines, like Bands.

This is a little confusing because by chance I took these pictures before and after the opening bar of the day session which the data series follows, so things shifted quite a bit from one picture to the next. Sorry about that. Nbd.

Later I have added an EC chart which actually shows how helpful the lower band has been in indicating support levels. Perhaps it is often like this in trending moves, but the point is: now the lines are plotting dynamically and staying there bar by bar it is much easier to track such behaviours whereas with only one horizontal line at the current level one cannot do this.

The White Dash line is the RT POC. The dash-dot dark blue line is the VWAP based on session beginning at 3.00 am. The thin magenta lines are the Standard Deviation 1,2,3 off the VWAP. The horizontal dashed blue line and the horizontal dashed red line above it are the previous session VAB and POC. Higher up is a similar horizontal dashed (gold) line indicating previous session VAT.

(Other Indicators on Chart: There is also a band indicator I wrote which in this case shows the standard deviations around the VWAP, although it can plot of a variety of different moving averages and combination of averages and the bands can be calculated in a variety of ways. I am going for very simple charting these days and plan to use just the VWAP, the SD bands, and the Value Area plots on the main charts, with a couple of basic oscillators below, one of which plots the skew and trend based on the DValue calculations and is posted in the original DValue thread.)
