Visibility graphs VGRSI

VGRSI — Visibility Graphs Relative Strength Index is a technical indicator for MetaTrader 5 based on the concept of visibility graphs applied to financial time series.

Unlike classical oscillators that mainly use local price changes, VGRSI analyses the geometric structure of price movement. It detects selected past points that remain “visible” from the current price in the time–price plane and uses them to estimate the relative strength of upward and downward movements.

The indicator is scaled to the familiar 0–100 range, making its interpretation similar to RSI, but with additional information derived from the structure of the price trajectory.

VGRSI can be used to support market analysis, signal filtering, trend confirmation, and the identification of possible impulse or regime-change areas.

The VGRSI indicator was developed by the author of the scientific publication “Visibility graphs can make money in financial markets”, available on arXiv, and the author of that publication is also the seller of this product in the Market.

Main features

• Visibility-graph-based analysis of price movement.
• RSI-like output scaled from 0 to 100.
• Uses both price amplitude and frequency information.
• Two calculation modes: A0 and A1.
• Can be applied to different symbols and timeframes.
• Designed for use in manual and automated trading workflows.
• Developed from an original research concept described in the attached publication.

Indicator modes

A0 mode
Combines amplitude and frequency information. It can be useful as a trend or persistence filter because it reacts when directional dominance is sustained.

A1 mode
Compares amplitude dominance with frequency dominance. It may help identify impulse-like movements or possible regime changes.

Inputs

Window Size 
Defines the length of the aggregation window used to calculate the indicator.

Window Visibility
Defines how far back the visibility relation is checked.

Aggregation Mode
Selects the calculation variant:

• A0 — mean aggregation of amplitude and frequency strength,
• A1 — ratio aggregation.
