Welcome to HIZOA.
HIZOA is focused on the development of analytical tools for traders who want to look beyond price alone.
Financial markets contain layers of information that are not always immediately visible on a standard chart. Market structure, volume behaviour, directional flow, momentum, support and resistance, changing volatility and market activity can all provide additional perspectives on what is happening beneath the surface.
Our goal is to develop tools that make this information clearer, structured and practical to observe.
WHY HIZOA?
The name HIZOA is inspired by astronomy and the HI Zone of Avoidance (HIZOA) surveys.
Large areas of the universe are difficult to observe because gas, dust and stars within our own Milky Way obscure what lies beyond. By using different observational techniques, astronomers can nevertheless detect and study structures and galaxies hidden from ordinary view.
That concept immediately connected with the philosophy behind our tools.
STRUCTURE BEYOND THE VISIBLE
Markets contain considerably more information than price alone can immediately show.
Different forms of analysis can reveal additional structure in volume, momentum, directional behaviour, volatility, market activity and the interaction between price levels.
HIZOA is not about predicting the future.
Our tools are not designed to tell traders what they must buy or sell, nor do we believe an indicator should pretend to know what the market will do next.
Instead, we focus on observation, visualization and structure.
Observe the information.
Understand the structure.
Make your own decision.
That principle remains at the core of everything we build.
The trader always remains in control.
DEVELOPMENT THROUGH RESEARCH
As HIZOA has developed, our approach to testing has evolved as well.
Visual chart testing remains important, but we wanted the ability to investigate indicator behaviour much deeper and on a considerably larger scale.
For this reason, we developed our own HIZOA Indicator Optimization Suite.
This internal research environment allows us to systematically examine how an indicator behaves across different parameter values, instruments, timeframes and historical periods.
Although the Suite itself is still under active development and testing, it has already made a significant difference in the way we can research our tools.
Instead of manually changing individual settings and evaluating a limited number of charts, we can perform thousands of targeted tests on calculation settings in a relatively short period of time.
The resulting indicator output can then be analyzed to understand what actually changes when a parameter is adjusted.
This allows us to investigate areas such as:
• Structural and directional persistence
• Confirmation behaviour
• Reversals and changing market conditions
• Parameter sensitivity and interaction
• Differences between instruments
• Differences between timeframes
• Stability across different historical periods
• Whether additional filtering genuinely improves an indicator's behaviour or simply introduces additional delay
This creates a much deeper testing process than visual observation alone.
Importantly, the HIZOA Indicator Optimization Suite is not a trading-strategy or profitability optimizer.
It does not use profit/loss, entries, exits, stop losses, take profits, lot sizes or drawdown to determine whether an indicator setting is better.
Its purpose is to understand the indicator itself and evaluate the behaviour of its calculated output.
The knowledge gained from this research can contribute to better calibrated settings, improved automatic profiles and more thoroughly tested future upgrades across HIZOA tools.
The HIZOA Indicator Optimization Suite is currently an internal development tool and is not intended for sale.
As the project continues to mature, however, we may reconsider this in the future.
STRATEGY RESEARCH — A SEPARATE DEVELOPMENT PATH
Alongside our indicator research, we are also working on another testing environment with a fundamentally different purpose.
Where the Indicator Optimization Suite focuses entirely on understanding and improving individual analytical tools, this separate project focuses on trading-strategy research.
The objective is to investigate how different HIZOA tools may work together when combined within complete trading concepts.
This environment is being developed to examine elements such as:
• Combinations of analytical tools
• Entry conditions
• Stop-loss placement
• Take-profit methods
• Trade management
• Drawdown
• Other strategy-related variables
Keeping these two research environments separate is important.
An indicator can be evaluated on whether it performs its intended analytical function consistently without making assumptions about profitability.
Strategy research asks an entirely different question: what happens when analytical information is combined with actual trading rules?
By separating those two areas, we can research both without confusing indicator quality with trading performance.
THE HIZOA ECOSYSTEM
HIZOA is not built around a single indicator or one specific method of market analysis.
It is a growing collection of independent analytical tools, with each development examining the market from a different perspective while following the same underlying philosophy.
Our research and development covers areas such as market structure and dynamic price levels, volume behaviour and directional flow, momentum and divergence, trading sessions and market activity, spread and timing information, compression and expansion, event-related market awareness and other forms of market behaviour that may provide useful context beyond price alone.
Some tools focus primarily on visualization. Others examine structural behaviour or provide practical information directly on the chart.
Each tool is developed to remain independently useful.
At the same time, different forms of analysis can complement one another, allowing the same market to be observed from multiple perspectives without requiring one HIZOA product to depend on another.
The HIZOA ecosystem will continue to evolve as new concepts are researched, tested and developed.
Not every idea or research concept will necessarily become a product.
Development is driven by whether a concept can provide clear, practical and meaningful analytical value.
FROM NOVA TO HIZOA
HIZOA originated from development that initially began under the NOVA name.
What started with individual market-analysis tools gradually developed into a much broader collection of ideas, indicators and research projects.
As that work expanded, it became clear that these developments shared the same underlying philosophy and were becoming part of something larger.
HIZOA became the identity connecting that work.
The transition from NOVA is therefore part of our development history, while HIZOA is the identity moving forward.
OUR PRINCIPLE
Markets will always contain uncertainty.
No indicator can remove that uncertainty, and no analytical tool should make promises about what the market must do next.
What we can do is continue researching, testing and developing tools that help make relevant market information easier to observe, interpret and understand.
That is what HIZOA is built around.
Provide information rather than promises.
Observe the information.
Understand the structure.
Make your own decision.
The final interpretation — and every trading decision — remains with the trader.
HIZOA
Structure Beyond the Visible
A New Way of TestingBehind the scenes,
HIZOA has been developing a new Indicator Optimization Suite, designed specifically to improve the way we develop, test and validate our analytical tools.
The Suite is currently still in its own testing and development phase, but it has already made a significant difference in the depth and efficiency of our testing process.
Where individual settings previously required extensive manual testing and chart observation, the Suite allows us to perform thousands of targeted tests on individual calculation settings in a relatively short period of time.
Parameters can be systematically examined across different values, timeframes, instruments and historical periods.
Instead of simply looking for a setting that appears visually suitable, we can analyze what actually changes inside the indicator and how those changes affect its intended function.
The Suite can examine areas such as directional persistence, structural changes, reversals, confirmation behavior, parameter interactions and stability across different market environments.
This allows us to investigate questions such as:
- Does a setting remain consistent across multiple timeframes?
- Do different instruments benefit from different structural calibration?
- Are confirmed directional changes stable afterwards?
- Does additional confirmation genuinely improve the output, or does it mainly introduce additional delay?
- Can instrument-specific and timeframe-specific profiles improve automatic calibration?
- Does an improvement remain visible when tested over a much larger historical period?
Importantly, the HIZOA Indicator Optimization Suite is not a trading-strategy or profitability optimizer.
It does not use entries, exits, profit/loss, stop losses, take profits, lot sizes or drawdown to decide whether an indicator setting is better.
Its purpose is to analyze and understand the indicator itself and the quality of its calculated output.
The first extensive calibration work has already shown how much more deeply individual settings can be investigated when thousands of controlled tests can be performed and compared systematically.
The results of this research may lead to better calibrated default settings, improved automatic instrument and timeframe profiles, and more thoroughly tested future upgrades for existing HIZOA products.
And There Is More in DevelopmentAlongside the Indicator Optimization Suite,
development has also started on a separate testing suite focused on trading strategies.
This is a fundamentally different research environment.
Where the Indicator Optimization Suite studies the internal behavior of individual HIZOA tools, the strategy-focused Suite is intended to research how multiple HIZOA tools can work together within complete trading concepts.
This includes testing combinations of HIZOA tools together with elements such as entries, stop losses, take profits, drawdown, trade management and other strategy-related variables.
The objective is to keep these two areas clearly separated: one environment for improving and validating the tools themselves, and another for researching what happens when those tools are combined into complete trading approaches.
The HIZOA Indicator Optimization Suite is currently an internal development tool and is not intended for sale.
However, as development continues and the Suite becomes more mature, we may reconsider this in the future.
For now, its primary purpose is simple:Test deeper. Understand more. Build better tools.
HIZOA — Structure Beyond the Visible.
HIZOA Volume Reversal Flow Volume Pressure, Reversal Development and Directional Confirmation HIZOA Volume Reversal Flow is an analytical volume oscillator designed to visualise bullish and bearish pressure, identify developing volume reversals and reduce distracting counter-flow noise during clearer directional conditions. Instead of treating every opposing volume bar as equally meaningful, the indicator evaluates volume intensity, directional flow, price behaviour and multi-stage
HIZOA Candle Statistics Objective Candle Structure, Market Activity and Pattern Recognition HIZOA Candle Statistics is a compact informational and educational indicator that provides a clear numerical view of the current candle and the most recently closed candle. Instead of producing buy or sell signals, the indicator helps traders understand the structure and relative activity of the candles currently shaping the market. By displaying the proportions of the candle body, upper wick and lower
The time has come to bring a new evolution of our Volume Flow concept to life.
What originally began as Volume Flow during the NOVA generation has continued to evolve — shaped by development, testing and a growing focus on identifying meaningful changes within market flow.
Today, we are proud to introduce its next generation:
HIZOA Volume Reversal Flow
Built upon the foundation of the original Volume Flow concept, this new HIZOA indicator goes further by combining volume pressure, directional flow and structured reversal detection within a single oscillator.
At the heart of this evolution is a new three-stage reversal sequence, designed to distinguish an initial reversal impulse from genuine follow-through and confirmation.
Reversal Impulse 1/3 → Reversal Confirmation 2/3 → Flow Reversal Confirmed 3/3
Rather than highlighting every change in direction, the system filters the underlying flow and only marks reversal stages when their individual conditions are met.
The familiar Volume Flow foundation remains — but its ability to expose changes beneath the visible price movement has evolved.
HIZOA Volume Reversal Flow is currently in active development and testing. The indicator will continue to be evaluated across different markets, timeframes and market conditions before the final release version is prepared.
From NOVA Volume Flow to HIZOA Volume Reversal Flow.
The evolution has begun.
HIZOA
Structure Beyond the Visible.
The tool provides a quick visual overview of candle structure, including the relationship between the body, upper wick, lower wick, total range and recent average activity. This can help traders better understand current price behaviour without adding trade signals or unnecessary complexity to the chart.
Simple. Objective. Accessible.
HIZOA Candle Statistics will be available completely FREE on the MQL5 Market.
The tool is still under development, so its final layout, calculations and available features may be refined before release.

HIZOA Clean Volume Flow provides a clear visual representation of directional volume pressure. No complicated dashboard and no unnecessary signals. The indicator presents the information in a clean and easy-to-read format: Green bars above zero indicate bullish volume pressure. Red bars below zero indicate bearish volume pressure. Bar height and color intensity reflect the strength of the current tick volume compared with its local average. The status display shows the symbol, timeframe, volume
HIZOA RSI Divergence Oscillator is a visual market-analysis tool designed to automatically detect and display regular bullish and bearish RSI divergences between price and momentum. Divergence can be an important indication that the relationship between price and momentum is changing. However, during active trading it is surprisingly easy to overlook — especially when monitoring multiple markets or timeframes. HIZOA RSI Divergence Oscillator continuously analyzes price structure and RSI
HIZOA SPREAD AND TIMER PANEL is a clean and practical information utility for MetaTrader 4. It displays the current spread, rolling average spread, candle closing time and daily closing time directly on the chart. The panel automatically adapts to the active symbol and timeframe, allowing traders to monitor essential spread and timing information without unnecessarily covering important chart areas. HIZOA Spread and Timer Panel is available completely free of charge. MARKET CLOSE AWARENESS HIZOA
HIZOA Market Sessions is a professional market-session and volume-flow visualization tool designed to provide a clearer view of when market conditions change, which major trading session is active, and how volume pressure develops around those transitions. Instead of displaying trading sessions only as simple time blocks, HIZOA Market Sessions combines session timing with integrated volume-flow analysis . This allows traders to view both the time structure of the market and the activity
HIZOA Dynamic Support & Resistance is a clean, adaptive market-structure indicator for MetaTrader 4, designed to visualize dynamic support and resistance across multiple market horizons. Instead of displaying only one fixed support and resistance calculation, the indicator continuously analyzes three different historical lookback periods. This creates three dynamic resistance levels and three dynamic support levels, allowing traders to view short-, medium- and longer-term market structure
The next NOVA project is already taking shape.
Built around the major market sessions, with a clean visual view of Sydney / Asia, Europe and USA — including pre-market transitions, rollover periods and live session status.
And after what we learned while developing NOVA Clean Volume Flow...
let's just say this one isn't finished yet.
NOVA Market Sessions
Currently in development.
Currently in the final testing and development phase.
See directional tick-volume pressure at a glance. Green shows bullish pressure, red shows bearish pressure, and bar strength highlights changes in relative volume.
With automatic profiles from M1 to Monthly, the indicator adapts instantly when the chart timeframe changes.
No complicated dashboard. No unnecessary signals. Just clean, practical volume-flow information.
NOVA — Next-generation Optimized Visual Analysis
The NOVA Dynamic Support & Resistance Indicator has been extensively tested and further refined following the initial free release.
Testing has been performed across different market types and timeframes, including Forex, Cryptocurrencies, Commodities, Metals and Indices, to evaluate the indicator under a wide variety of market structures and conditions.
During this testing process, several issues in the original free version were identified and corrected. The indicator has subsequently been further optimized and refined.
The result is the improved and finalized paid version of NOVA Dynamic Support & Resistance, featuring refined calculations, improved projections, optimized automatic timeframe settings and more consistent support and resistance visualization.
The previous free version will no longer be offered, as it does not include all corrections and improvements implemented in this final release.
This final release replaces the original free version.
Following extended live testing across different symbols, timeframes, brokers and chart configurations, several unexpected practical situations have been identified in our currently released tools.
For this reason, the existing NOVA tools will be made available free of charge while further improvements are being developed.
The indicators remain functional and useful, but our goal is to improve their stability, consistency and behaviour under a wider range of market and platform conditions.
Planned improvements may include:
• Better handling of broker-specific conditions
• Improved behaviour across symbols and timeframes
• More consistent chart-object management
• Refined calculations and visual presentation
• Additional stability and usability improvements
Existing users will continue to receive future updates through the product pages.
We prefer to be transparent, keep improving our work and provide users with better versions instead of pretending that unexpected situations do not exist.
Thank you to everyone who downloads, tests and supports the development of NOVA trading tools.
