Volume profile is a charting tool that shows how much volume traded at each price level over a chosen period, displayed as horizontal bars on the side of the chart. It tells you where the market did the most business, not just when.
A normal volume bar shows volume per time period. Volume profile flips that around. Long horizontal bars mark prices where heavy trading happened; short bars mark prices the market moved through quickly. Three terms come up often:
- Point of Control (POC): the single price with the highest traded volume.
- Value Area: the range where roughly 70% of the volume traded.
- Low-volume nodes: thin areas where price tends to move fast.
A hypothetical example: over a month, a stock trades between ₹540 and ₹600, but the POC sits at ₹565. If the stock later falls back to ₹565, many traders expect buyers and sellers to engage there again, so it can act as support or a magnet.
The common mistake is using it on illiquid stocks, where a few large trades distort the profile. It works better on liquid stocks and index futures. Also, the period you choose changes the picture completely, so be consistent.
We teach volume profile alongside classic support and resistance in our Technical Analysis course, so you can see where both agree.
