The following applies to all NBA nodes

The Node Flow Model

Most node types expect as inputs 1 or more sets of 1 or more propositions, carry out some processing, and output a single set of 1 or more propositions. These sets are represented as child branches. Some node types expect a single child branch and some support an effectively unlimited number of them.

The exceptions are the Load Propositions elements, which don’t have any child branches, and the node that serves as final ‘root’ node, which doesn’t have an output branch (instead passing its output to the requestor that initiated the strategy execution).
