# Overview
The Vertex Oscillator is a proprietary momentum-based oscillator designed to detect periods of deep undervaluation (accumulation) and excessive euphoria (distribution) in markets.
By combining price deviation, volume normalization, and volatility scaling, the indicator identifies extreme conditions and provides actionable signals for both traders and analysts.
The Vertex Oscillator helps traders identify undervaluation, euphoria, and neutral market states. Beyond zone signals, it can also be used to spot bullish or bearish divergences between price and momentum.

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
