What is High Volume Node (HVN)?

There is no single standard for "how high" or "how low" counts. Software typically uses a threshold such as a percentage of the POC's volume, or a local peak or valley with some minimum separation. Different settings produce different nodes. This is why it is more honest to think of HVNs and LVNs as zones, a few ticks or a dollar or two wide, rather than single-tick lines. A very small row size can also produce dozens of tiny "LVNs" that are just noise.
