Options Trading As A Graph

---

Introduction

This GraphGist will begin to explore how stock option data can be modeled as a graph, some simple Cypher queries for calculating payout at expiration for an options contract and a very basic look at finding profitable options trades given a specific forecast. Please note that some of the concepts here have been simplified and are only meant as an educational overview of exploring Neo4j and graph data modeling.

Analysis over Finance and Portfolio Management

• How much percentage people spend money on a particular liability, say loans.

• How much percentage does a particular asset contribute to average earnings.
