I’m a Tokyo-based trader-developer focused on one thing: building transparent, mathematically grounded MT5 tools that make market microstructure events observable, comparable, and testable—without hype.
My path
I began trading in the mid-2000s and quickly learned two enduring lessons: - Version: 1.5

Overview
TriParity PRO LiveGAP is a real-time parity monitoring dashboard for MetaTrader 5. It is designed to help traders observe triangular parity conditions more clearly by comparing the live cross price with a synthetic cross derived from two related instruments.
In this description, a triad means the relationship between three instruments. A common example is EURUSD, USDJPY, and EURJPY.
This product is not a signal generator and does not place trades. It is a visual monitoring and validation tool for traders who want to review parity structure, quote timing, and symbol consistency on one screen.
What it does
LiveGAP displays each triad in one row and shows:
- TRIAD structure
- Live Bid and Ask for AB, BC, and AC
- Spread in pips
- Tick age in seconds
- Synthetic Bid and Ask
- Gap in pips
- Band status
- Data quality status
The synthetic cross is calculated from the two component instruments. The band is based on spread-aware synthetic pricing, which gives a more practical comparison than a simple mid-price check alone.
This makes it easier to review whether the live cross is trading inside or outside the current theoretical range.
Why it is useful
The main purpose of LiveGAP is to make parity conditions visible in real time in a clear and structured format.
The dashboard can help the user:
- monitor multiple triads on one panel
- compare live price and theoretical price without manual calculation
- notice stale ticks or delayed quotes more quickly
- separate price movement from possible data-quality issues
- review broker symbol consistency across FX and XAU-related triads
When the live cross moves outside the synthetic band while quality remains acceptable, the dashboard shows that the current market price is outside the spread-aware parity range. These events may be visible on screen but may still be difficult to trade in retail conditions because of latency, spread changes, slippage, and execution limits.
Quality and quote timing
The dashboard includes a built-in quality status shown as OK, WRN, or BAD.
OK means the data is currently usable for monitoring.
WRN suggests possible quote timing issues or less reliable conditions.
BAD indicates missing or inconsistent data.
Tick age is also displayed in seconds so the user can check whether one side of the triad is updating later than the others.
Symbol handling
The indicator is designed to work with common broker symbol variations.
It supports:
- automatic symbol resolution for broker prefixes and suffixes
- automatic inversion when only the reverse symbol is available
- manual symbol aliases in the Inputs when needed
This helps the indicator adapt to different broker environments without changing the core triad templates.
Coverage
The indicator monitors 21 predefined triads, including major FX combinations and XAU-related triads.
If a required symbol is not offered by the broker, the related row may show a lower quality status or remain unavailable. This is expected behavior.
An optional compact World Clock is also available on the panel for Tokyo, London, and New York using fixed offsets.
Typical use
A common use of LiveGAP is:
- Attach the indicator to any chart in MetaTrader 5.
- Make sure the required symbols are available in Market Watch.
- Review the dashboard for gap, band status, tick age, and quality status.
- Use manual aliases if your broker uses non-standard symbol names.
Notes
This product is a monitoring and diagnostic tool only. It does not provide investment advice and does not guarantee any trading result.
Parity deviations can reflect spreads, liquidity conditions, symbol differences, quote timing, and broker feed characteristics. Events shown outside the band may be short-lived and may not be executable in retail trading conditions.
Output depends on broker symbol availability, tick quality, and current market conditions.
TriParity PRO LiveGAP is part of the TriParity PRO product line. Related products such as Scanner and Catcher are available separately.
