Volume Profile, Market Profile and the value area
Two profiles can look similar while measuring different things. Check what fills the bars.
Distinguish volume-at-price from TPO activity and interpret POC, VAH and VAL.
Volume Profile groups executed volume by price over a selected period. Its POC is the price row with the greatest volume, not the average transaction price.
A TPO or Market Profile display groups time-block activity at price. Its time-based POC can differ from the volume POC; do not interchange the measurements.
VAH and VAL are the upper and lower value-area boundaries under a configured calculation. A 70%setting is common, but algorithms, row sizes and sessions affect the result.
A value area describes past activity. It does not mean the next price has a 70%chance of staying inside or that its boundaries must act as support and resistance.
Let’s work through it
- Choose period and data unit
- Find the correct POC
- Read the value-area settings
Let’s use numbers · hypothetical example
Volumes at prices 100,101,102,103,104 are 10,25,40,20,5 units. Volume POC is 102. A TPO record could instead have most time blocks at 101; the two POCs need not match.
Easy mistakes to watch for
- POC equals average price
- TPO equals volume
- 70%is a future probability
Keep in mind
Spot broker tick-volume profiles do not show all global Forex transactions. Know whether your feed measures volume or activity proxies.
Your turn
Build the five-row volume histogram and label POC. Then change the session and note why the profile could change.
A quick check before we move on
Which is the volume POC in the example?
- 104
- 102
- 101
Check answer
102 The 102 row contains 40 units, the largest row. POC is the highest-volume row, not the mean.
