I trade on live accounts myself, so I build EAs the way I'd want to run them.
What I build:
• Expert Advisors and indicators for MetaTrader 4 and 5 (MQL4 / MQL5)
• A written strategy turned into a configurable EA — everything adjustable sits in the inputs
• Risk management: ATR stops, break-even, partial closes, trailing, daily loss limits, drawdown protection, prop-firm rule sets
• Fixing, auditing and explaining existing EA code, including code from AI tools and no-code builders
• Backtesting and optimisation in the Strategy Tester on real tick data
Also:
• Python — MT5 bridges, data analysis, backtesting tools, log and latency analysis
• C++ — MQL is C++ based; I work in both
How I work: I ask before I code. You get the full source, commented and unlocked. I test on real ticks before I hand it over. If I think your idea won't do what you expect, I say so first.
I don't promise a profit factor, a win rate or a monthly return. Nobody can do that honestly.
You can check my work: two EAs in the MQL5 Market — Gorilla UltimateBeast Forex and GorillaBeast ScalperPro Gold2 — and a MetaTrader 5 signal, ThreeD Bet Forex MAX, running on a real account since March 2026. More EAs are in development.
I'm new to Freelance and my rating here is empty. I'd rather say that than hide it.

Prices have surged to record highs of around €4,300–4,500 per ounce , with banks like Goldman Sachs and J.P. Morgan forecasting further gains toward €4,600+ . With it came extreme volatility — sharp spikes, widened spreads, geopolitical shocks. This is exactly where ordinary systems fail. GorillaBeast GOLD 2 was tested over the demanding period of 2023–2026 (98% real ticks) —
Gorilla Ultimate Beast Forex is an automated trading system (EA) for MetaTrader 5 , designed for fully rule-based trading on forex instruments without the need for manual intervention. Transparency is important to me, which is why the performance and ongoing statistics are available from a real account via independent Myfxbook monitoring. The EA is intended for traders who want clearly defined entry/exit rules and the ability to run a more conservative or more dynamic approach depending on their
