I think not, but maybe I'm wrong.

I'm familiar with the Market Profile charts from eSignal and Market Delta. The software relies on the user to merge or segment the distributions into meaningful clusters (market units). The software makes no attempt to qualify the input data before displaying a VA.

Here's what I mean. Consider [1] a trend day, and [2] a double distribution day.

[1] A trend day predominantly has higher highs or lower lows. The computed Mean, VA_H and VA_L would move higher or lower during the day but wouldn't serve as trading reference points they same way they could on a balanced (normal or normal variation) day. On a trend-up day price will likely be above the VA. The ever rising VA_H and VA_L prices on a trend-up day don't help me. I don't look for a VA on a trend day.

[2] A typical double distribution day will have an early price cluster, then a breakout from that cluster, and a distinct later price cluster. The computed Mean might be midway between these clusters, perhaps a price with hardly any volume at all. A VA computed from this mean would encompass prices shown to be unpopular. The POC (price with the most TPOs) might be found in the earlier price cluster. When a mid-day event, like releasing FOMC minutes, causes a double distribution, I will split the day into two distributions, they will provide me with more useful reference points.

The POC can temporarily be outside the calculated VA. Under such circumstances I think the VA should be disregarded. I would look for VA in a longer time-frame distribution, or shorter under special circumstances.
