A Volume Profile is similar to a Market Profile inasmuch as they both show a profile (a bell curve) against the Y-axis of the chart to represent the most traded area(s) of the time period that they have been constructed against.
The major difference, a significant one, is that a Volume Profile is constructed using the volume traded at each price while Market Profile is constructed based on time brackets traded that the market traded at each price called TPOs.
Volume Point of Control
The most traded price (the one with most volume) is defined as VPOC, or Volume Point of Control.
Against each price on the vertical axis you will typically see a bar that represents the number of contracts that were traded at that price. This type of chart can also be normalized to show a percentage of the day’s total volume traded at that price. Volume Profile is agnostic about time that the market remained at each price.

What Information the charts will provide
Volume Profile Charts shows the distribution of volume across the prices. From my observation the Volume profile chart will provide the levels to trade intraday/positional. In the above 10min nifty chart chart you can see that High volume on the Y-AXIS is built near 5594 zone. And yesterday’s dip below 5594 in nifty could result in that 5594 zone could be the resistance zone for the intraday. And based on the market movements the high volume built up bar levels also move dynamically with respect to time and constant observation is required to trade based on these levels.
This is just one observation. If you have more observation on volume profile charts post your charts here for more clarification.
