Kazutaka Yamamoto / Profile

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:
(1) edges come and go, and (2) the only durable advantage is a repeatable process with clear validation.
Over time I moved my focus from equities to FX, where price formation is more continuous and technical behavior is easier to study systematically.

What I’ve worked on over the years
My work has evolved through multiple phases—risk management, multi-timeframe structure, time-of-day behavior (Tokyo/London/NY), and correlation frameworks. Correlation can be useful, but it breaks down precisely when markets matter most: during shocks, liquidity gaps, and sudden repricing. When pairs diverge, the key question becomes: what’s truly moving, and what’s just lagging?

The breakthrough: Triangular parity distortions
Tri-currency identities provide a cleaner lens. In any FX triad, relationships such as:

EURJPY ≈ EURUSD × USDJPY

should hold—yet in real markets they periodically distort due to spreads, latency, liquidity fragmentation, and aggressive flow.
Those short-lived distortions are often visible, even if they’re not reliably executable in retail conditions. That distinction—observe and validate vs. claim tradability—is central to how I build tools.

What I build now: TriParity PRO (MT5)
TriParity PRO is a premium line of MT5 tools built around a single principle:
AB × BC vs. AC—measured with real Bid/Ask, shown in a way you can verify.

TriParity PRO LiveGAP — an “arbitrage-gap” dashboard that displays live Bid/Ask, synthetic cross (SYN Bid/Ask), gap in pips, BAND IN/OUT, and data-quality grading to separate feed issues from true dislocation.
TriParity PRO Scanner — multi-timeframe triad monitoring and prioritization (designed to narrow the field quickly and consistently).
TriParity PRO Catcher — a focused capture layer designed to surface specific distortion conditions with minimal noise.
(Each tool is designed to stand alone; no bundling assumptions.)

What you can expect from my work
No black boxes: clear visuals and definitions you can audit on your chart.
Engineering-first design: reliability, performance, and broker-reality handling (symbol variants / inversion).
Practical presets with conservative defaults and a documentation-first mindset.
Direct support via MQL5 Messages and the Comments tab (best-effort outside recommended setups).

If you value practical math and verification over marketing claims, you’re in the right place. Feel free to try the demo, add to Favorites for updates, and message me if you have a specific environment/question.
