MQL5/MQL4 Developer - Expert Advisors and Indicators à ralphivansimeon.vercel.app
I build and audit automated trading systems for MetaTrader 5, with most of my work on XAUUSD.

Two of my tools are published on the Market: a configurable basket framework for gold, and a risk engine that supplies the sizing, stops, exposure limits and restart safety for an entry signal you provide. Both are sold as frameworks rather than signals, and neither makes a performance claim - I would rather tell you what a tool does than what it supposedly earns.

Risk is where most accounts actually die, so it is where I spend the time: position sizing from the broker's own tick value and volume step rather than an assumed pip value, per-trade and daily loss caps, spread and stops-level guards, session gating, and recovery after a terminal restart with a position still open.

I also write about the parts that are genuinely hard to get right - passing Market validation, the ways a Strategy Tester run can quietly mislead you, and why a stops level of zero does not mean there is no minimum distance.

MQL5/MQL4: Expert Advisors, indicators, trade panels and utilities. Full-stack background (TypeScript, React, Next.js, Node) when a strategy needs a web or mobile side.

Based in Dubai, working with clients worldwide. Clear specs, fixed deadlines, and all communication inside the MQL5 order.

Most lot size calculators assume one pip is worth ten dollars. That assumption is wrong on gold, wrong on indices, wrong on JPY crosses, and wrong on every account not denominated in USD - which is to say, wrong exactly where oversizing hurts. This one asks your server instead. It reads the tick value, tick size, point size, volume step and margin requirements actually published for the symbol on your chart, so the number it gives you is the number your account will accept. How it works Attach

Code publié Position sizing from risk, using the broker's own tick value and volume step
La taille de la position est calculée à partir d'un montant de risque, lui-même déterminé en fonction de la valeur réelle du tick du symbole, de la taille du tick et du pas de volume, plutôt qu'à partir d'une valeur de pip supposée. Le volume est toujours arrondi à l'unité inférieure, et lorsque votre risque est inférieur au lot minimum, le programme vous le signale et indique le coût réel de ce lot. Aucun état du terminal n'est requis, ce qui permet de tester la logique de calcul de la taille de la position hors ligne — un script de test comportant 41 assertions est fourni.

Your EA does not lose money because the entry was wrong. It loses because nothing stopped it. A bad signal costs you one trade. A missing risk layer costs you the account. Yet almost every gold EA spends its complexity on entries and treats protection as an afterthought - a stop-loss input and a comment about money management. Aurum Risk Core is the other half. It is the chassis: sizing, stops, basket control, exposure limits, entry gating, restart safety, and the instrumentation to see all of

Xau Basket Scalper is a configurable trading framework for MetaTrader 5, not a signal in a box. You choose the entry engine, the risk model and the session windows. The EA enforces the risk limits, manages the basket, and tells you exactly what it is doing and why. It is built around one idea: an EA should never be silently wrong. Every skipped trade is logged with its reason. Every state that could cost money is detected and shown on the chart rather than discovered later in your account
