Independent Belgian developer of automated trading systems, focused on robustness, execution reliability and risk control.
Over the past years I have designed, tested and run multiple automated trading systems on live capital. Like many developers, I experimented with different approaches early on, including grid and martingale based systems. Some performed well for a period of time, but over the long run they proved too fragile under real market conditions.
That experience shaped how I build strategies today.
I don't believe in "THE PERFECT" systems. Even the best strategies will have losing days, weeks or sometimes months. My goal is not short-term performance, but long-term stability and controlled risk.
Most of my current research and development focuses on Gold (XAUUSD) and volatility-driven systems.

Live Performance Update
I build my EAs to prove themselves where it matters most: under real market conditions.
VEX Gold has now been running live for five months, achieving approximately 30% profit with around 5% drawdown. It is the lower-risk option, focused on steady growth and controlled risk.
VEX Fury now has three months of live signal history and is approaching 80% profit. It takes a more aggressive approach, combining different engines designed for different market regimes.
Both EAs use a single-position approach. No grid, no martingale and no recovery system.
Different risk profiles, but the same focus on robust live performance.
The current VEX Fury price is introductory and will increase to $199 soon. If you were waiting to see real live results first, there are now three months of performance to review.

Quick update on the live signal 👇
Summer gold hasn't been easy - choppy, indecisive, plenty of fakeouts. VEX GOLD is still nearly +5% up on the month and sitting at +29.45% YTD.
Vantage market new Live signal currently sitting at: +15% this month.
Not the flashiest month, but stability through the messy periods is exactly what the system was built for.

Overfitting in Expert Advisors: Why a Perfect Backtest Means Nothing
12 August 2026, 08:32
Core idea A good strategy learns the signal. An overfit strategy memorises the noise. That is why a slightly less impressive backtest can be much more valuable than a flawless one: robustness matters more than cosmetic smoothness. Every week someone sends me a screenshot...

New Vantage Markets live signal is now running. Recent BlackBull execution has been inconsistent, so I’m moving the main focus to Vantage for the coming weeks.

Coming soon: a new XAUUSD a faster companion to VEX Gold
I'm developing a new XAUUSD system built for shorter market movements and more frequent intraday opportunities. This is a separate product, not a replacement. VEX Gold remains my primary EA, with its structured M15 strategy suited to both standard live and prop firm accounts. The new system is an additional option for traders who prefer a faster, short-term style.
Because it trades more frequently, execution quality matters more than for any M15 system. Most short-term EAs look good in backtest and fall apart live on spread, commission and slippage. That's exactly why I'm validating live execution across multiple brokers before I confirm a release, and why I'll publish the recommended broker conditions (max spread, commission level) at launch, so you know the environment it's built for.
It's designed to work on both small and larger accounts, from around $100 where the broker offers a 0.01 minimum lot and suitable conditions.
For the first 48 hours after launch, it will be offered between $99 and $129. The price will then rise toward $299 as the regular price. Existing VEX Gold users receive a special rebate on top of the launch price as a thank you for their support.
No release date is fixed yet. Broker validation comes first, and I won't launch a short-term system I haven't confirmed live.
Join the Telegram group or follow the MQL5 channel to get the launch price and release notice first.

IMPORTANT BROKER UPDATE
I am removing BlackBull from the recommended brokers for VEX. Recent live executions showed excessive slippage, causing entries far from the pending-order price.
In several side-by-side trades, BlackBull recorded losses while Vantage closed the same VEX setups in profit with almost no slippage.
Vantage RAW/ECN is currently my first recommendation. TMGM, Ultima Markets and VT Markets are also suitable alternatives, but always test your broker conditions on demo first.
If you use BlackBull, wait until any open VEX trade is closed before changing your setup.

VEX GOLD high risk account, new highs
The high risk signal just hit new highs. Up almost 10% this month alone, 34% in 6 weeks. $500 start.
Higher risk profile isn't for everyone, but for those who can handle the swings, it's doing exactly what it was built to do.

After many requests I created a VEX GOLD channel
Where I'll be posting the stuff that doesn't fit on the product page: latest updates, what's coming next, closed and open trades, and broker-by-broker comparisons so you can see how execution actually differs between them.
If you're running VEX or thinking about it, this is where the real-time picture lives.

VEX GOLD market note
Gold's been stuck in a tight range this week, roughly $4,000 to $4,200, with volatility drying up as the market waits on the Fed minutes and the Middle East situation.
Bollinger Bands are narrowing, which usually means everyone's sitting on their hands until a real driver shows up.
VEX keeps placing its pending stop orders around the current EMA levels like always, but in a tight range price just doesn't break through them cleanly, so fewer of them trigger. That's the filter doing its job.
It only takes the trade if price actually breaks the level, not when it drifts sideways and fakes out.
Fewer trades beats bad trades. The setups come through once the market picks a direction.

New week, new VEX Gold trade.
Monday just started and VEX already closed another clean XAUUSD trade. 🎯
The focus stays the same: controlled risk, fixed SL/TP, active trade management, no grid and no martingale.
Live results can change, but I’m happy to see the system continuing to follow its structure in real market conditions.
Last few copies remaining at the current price.

Added topic Why are people still using Martingale/Grid systems when its 90% chance of blowing your account?
Genuine question for anyone running automated systems. Why do people still buy grid or martingale EAs when most of us already know how these usually end? The equity curve looks amazing at first. High win rate, tons of small wins, barely any red days

VEX Gold live signal vs same-period backtest.
I always try to be transparent about the difference between Strategy Tester results and real live behaviour. Backtests are useful, but the real test is how the EA performs under live broker conditions: spread, slippage, execution speed and symbol behaviour.
This comparison shows the official MQL5 live signal curve next to the same-period Strategy Tester curve. The goal is not to claim that both will always match perfectly, but to show that the live behaviour is currently following the same general direction as the tested logic.
VEX Gold is built for XAUUSD with controlled risk, fixed SL/TP, active trade management, no grid and no martingale.
Past performance does not guarantee future results. Broker conditions matter, especially on Gold.
