Hi, I'm Jaume — an MQL5 developer focused on building clean, transparent trading tools.

I specialize in Expert Advisors and custom indicators for MetaTrader 5. My approach is straightforward: no martingale, no grid, no black-box magic. Just solid technical logic backed by proper backtesting.

What I build:

Expert Advisors (breakout, mean-reversion, indicator-based strategies)
Custom indicators (market structure analysis, signal detection, visual tools)
MQL4 to MQL5 migration and code modernization
Strategy optimization and debugging
Published on MQL5 Market:

Tokyo Trigger — Stochastic breakout EA for USDJPY H1 (backtested 2012-2025)
GBP RSI Buy Milker — Double RSI strategy for GBPUSD M1 (backtested 2003-2025)
My stack:

MQL5 / MQL4 (native MetaTrader development)
C++ style OOP with standard MQL5 classes (CTrade, CPositionInfo, CSymbolInfo)
Clean code with proper error handling and documentation

Currently available for freelance projects. I deliver on time, communicate clearly, and write code you can actually read and maintain.

Languages: English, Spanish, Catalan

Nasdaq Reversion A lightweight long-side mean-reversion Expert Advisor for the Nasdaq 100 index (NQ / USATECHIDXUSD) on H1. No martingale. No grid. No hedging. One position at a time. A hard stop on every trade. It waits for the index to get oversold within its trend, then takes one clean long with a fixed stop. No averaging into losers, no recovery games. How it works Oversold trigger: an RSI-based entry when the Nasdaq dips into oversold territory. Trend filter: an EMA filter keeps entries

Aurum Breakout A focused, single-pair Expert Advisor for GOLD (XAUUSD) on the H1 timeframe, built around a session-aware breakout strategy. No martingale. No grid. No hedging. No averaging down. One position at a time. If you have been burned by EAs that look perfect until one bad day wipes the account, this is the opposite philosophy: one clean directional trade at a time, with a hard stop loss on every position. What you risk is what you risk. Nothing hidden. How it works Session filter
