How to update the tree nodes after update property in one of the nodes?

[alexander_kaluz]

Hello everyone!
I've already read a topic about the triggers and how to use them, but I have algorithm problem, and don't know how to implement this using neo4j syntax.

The problem:
I have a tree of groups with license amount. For instance 200 total amount of license

If group is limited = false, then it has amount of license of first limited group minus amount from child groups that limited is true.
If I change amount in one of the limited group I have to recalculate amount of unlimited groups
The result should looks like this

How can I traverse from the root node and select all the nodes which are (limited = false) and if found group during traversal which is limited = true how can I skip its child?
I was thinking about DFS but I cannot understand how to work with it by using Cypher syntax.
Maybe someone has an idea how to implement traversal with skip points?
