Software & MT5 EA Developer | 30 years of programming | 7 years of trading at
30 years of programming. 7 years of trading. 5 published MetaTrader 5 Expert Advisors.

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.

EXPLORE MY WORK
• QuantumBit Pro — Bitcoin adaptive grid on H1, with an H4 trend filter, ATR spacing and basket exits. Grid positions accumulate exposure.
https://www.mql5.com/en/market/product/182583

• Gold Regime H1 Pro — gold trend/regime trading with volatility-based sizing and ATR management. Published as “Gold Range Grid Mean Reversion”; additional entries are disabled by default in v4.10.
https://www.mql5.com/en/market/product/182989

• Crypto Portfolio Trend — BTC and ETH breakouts managed from one H1 instance, with shared portfolio risk budgets.
https://www.mql5.com/en/market/product/182221

• Bitcoin Regime H1 Pro — Bitcoin regime following with volatility-based exposure rebalancing. Profiles with and without adding after adverse moves are available for comparison.
https://www.mql5.com/en/market/product/185775

• US Core Dip Portfolio — daily long-only core above SMA200, with three RSI dip tiers, across a configurable basket of US index and stock CFDs. One MT5 instance manages the basket.

Setup guide: https://www.mql5.com/en/blogs/post/777062

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.

Leveraged trading can cause substantial losses. Software protections are not guaranteed loss ceilings. Past performance does not guarantee future results.

Portfolio Allocation Planner — budget-to-lots dashboard and CSV kodunu yayınladı
Before configuring a basket, see which target weights fit your broker's minimum lots. Portfolio Allocation Planner turns an explicit hypothetical notional budget and percentages into a chart table: minimum-lot notional, lots rounded down, calculated allocation, target shortfall and row status. Recalculate on demand, inspect row tooltips, paginate longer lists, and optionally export the displayed snapshot to CSV. No trades are sent and no account balance, equity or positions are read.

Portfolio update — October 2026

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.

New release: QuantumBit Pro - Bitcoin Adaptive Grid EA (MetaTrader 5)

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.

I develop automated trading systems (Expert Advisors) for MetaTrader 5 with a single priority: performance that holds up in the real world — not just a good-looking backtest.

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.

A question before or after a purchase? Message me — I reply. Thank you for visiting my profile.
