MQL5 and MQL4 development, code review, and performance optimization for MetaTrader traders.
Two services. Both focused on making your code faster and more reliable.
You describe your trading idea. We build the Expert Advisor. You get the source code with documentation that explains how it works.
You send us your code (from a developer, a forum, or written yourself). We audit it and fix the problems we find.
Every audit report covers:
Pricing is per project and discussed after your free audit. You know the cost before work begins.
An actual client EA. Three problems found. Fixed in one afternoon.
iMA() handle created inside OnTick(): new allocation and memory leak on every tickiClose() called per bar in loop: 500 sequential time-series lookupsIsNewBar() guard: full trade logic runs on every incoming tickOnInit(), reused via integer ID. Zero leaks.CopyClose() fills entire 500-bar array in a single buffered callIsNewBar() guard: trade logic drops from ~5000 to ~1 execution per barWe see these issues regularly in client code.
Your strategy logic works but testing one year of data takes hours. Most of that time is wasted recalculating the same values on every tick.
Results diverge between strategy tester and real market. Hidden look-ahead bias, repainting, or timing issues.
You found a promising EA but have no idea if it's safe to run live. You need eyes on it before risking capital.
Your broker switched platforms and your EA won't compile. Logic needs to carry over cleanly.
"Sent my EA over on a Sunday evening. Had a full report with identified bottlenecks by Monday morning. Backtest went from 18 hours to under 5 minutes. I didn't believe it until I ran it myself."
"They found a logic error in my grid EA that was causing it to trade against itself under certain conditions. I had been running it live for months without noticing. Could have been very costly."
"Had a working MT4 strategy that needed to move to MT5 for a new broker. Done in two days, no logic changes, everything works identically. Clean code, proper documentation."
"The free audit alone was worth reaching out. Got a written breakdown of three issues I never would have found myself. No upsell pressure. Just honest, technical feedback."

How it works
Use the form below or open a support ticket. Send your code, describe the problem, or explain the strategy you want built.
We review your code or requirements and send you a written report or cost estimate. Free, no commitment.
You get the finished code with documentation. You own it. No ongoing fees.
Send us your code or describe what you want to build. We'll review it and send you a detailed report. Free.
Fast code needs fast infrastructure. Low-latency Linux servers in 9 datacenter locations, close to your broker.
