I’m Fabien Martino, a software developer with 30 years of programming experience and 7 years in trading. I develop MetaTrader 5 Expert Advisors for Bitcoin, Ethereum, gold and US index/stock CFDs, with five robots published on the MQL5 Market.
My MT5 portfolio has been published on the MQL5 Market since June 2026, with version updates, documented strategy rules and downloadable testing resources.

HOW I DEVELOP AND DOCUMENT
My work covers trend and regime filters, volatility-aware exposure, ATR stops and trailing, basket management, portfolio risk controls and execution checks. Features differ by EA and are explained on each product page.
The published tests show return, equity drawdown, profitable and losing periods, broker conditions and data limitations. Historical comparisons inform development; they are simulations, not independent forward validation or a live track record.

I started programming at 14: 30 years of software development and 7 years of trading experience. My four published MT5 Expert Advisors cover different approaches: a Bitcoin adaptive grid, gold regime following, BTC/ETH portfolio breakouts and Bitcoin volatility-based exposure rebalancing.
A clarification to my June introduction below: QuantumBit uses a grid. Risk controls, test models and features differ between products; they are documented individually. Historical tests are simulations, not a live performance record or a guarantee.
Start here: compare the strategies, download the version-specific SET files and inspect native MT5 reports, including losing periods.

I've just released my new MT5 Expert Advisor: a trend-filtered adaptive grid for Bitcoin (BTCUSD). Unlike blind martingale grids, it only adds positions in the direction of the H4 trend, banks profit on retracements, and exits the whole basket when the trend flips - with a hard floating-drawdown kill-switch and an optional capital-protection floor.
Highlights: ATR-spaced entries, capped levels and total lots (no unlimited martingale), trades both long and short, and a fully reproducible 6-year backtest on real broker data. Requires an MT5 hedging account and BTCUSD; a VPS is recommended.
Risk warning: trading leveraged crypto CFDs is risky and you can lose money. Backtests and past performance do not guarantee future results. Always test on a demo account first. This EA is a tool, not financial advice.
Limited launch offer: USD 99 for the first 10 purchases only. Only 9 places remain at this price. The price will then increase to USD 299. QuantumBit Pro 1.20 — adaptive Bitcoin grid for MT5 Trade Bitcoin from one H1 chart with an H4 trend filter, volatility-based grid spacing and basket exits. QuantumBit is designed for traders who understand grid exposure and want to inspect the strategy, settings and test evidence before using it.

Every system I publish is fully rules-based and trend-following. No martingale, no grid, no repainting. All decisions are taken on closed bars, and capital protection is built in from the ground up: fixed percentage risk per trade, portfolio-level risk limits, daily loss caps and an economic-calendar news filter.
I test each EA on real broker data using the 1-minute "every tick" model over multi-year periods, and I run my systems on my own accounts before they ever reach the Market. I present my backtests honestly, state their exact conditions, and never promise profits — because these systems are built to manage drawdowns, not to sell a dream.
