What We Do

Two services. Both focused on making your code faster and more reliable.

MQL5 / MQL4 Development

You describe your trading idea. We build the Expert Advisor. You get the source code with documentation that explains how it works.

  • Strategy automation from scratch
  • Custom indicators & EAs
  • MT4 → MT5 migration
  • Risk management modules
  • Multi-symbol & multi-timeframe logic

Code Review & Optimization

You send us your code (from a developer, a forum, or written yourself). We audit it and fix the problems we find.

  • Performance audit & profiling
  • Logic error detection
  • Backtest acceleration
  • Memory leak analysis

Every audit report covers:

Critical Logic errors, race conditions, incorrect position sizing, off-by-one bar issues
Performance Handle leaks, unnecessary recalculations, loop inefficiencies, tick overload
Design Strategy structure, entry/exit logic consistency, parameter exposure, code maintainability

Pricing is per project and discussed after your free audit. You know the cost before work begins.

Real Results

An actual client EA. Three problems found. Fixed in one afternoon.

Before
18:23:47
Backtest • 1 Year History • EURUSD M1
  • iMA() handle created inside OnTick(): new allocation and memory leak on every tick
  • iClose() called per bar in loop: 500 sequential time-series lookups
  • No IsNewBar() guard: full trade logic runs on every incoming tick
After
00:04:52
Same settings • Same data • Same results
  • Handle created once in OnInit(), reused via integer ID. Zero leaks.
  • CopyClose() fills entire 500-bar array in a single buffered call
  • IsNewBar() guard: trade logic drops from ~5000 to ~1 execution per bar
96% faster. Same entry and exit logic. Same trade results. No wasted compute.

Common Problems

We see these issues regularly in client code.

Backtest takes forever

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.

🐛

Works in backtest, fails live

Results diverge between strategy tester and real market. Hidden look-ahead bias, repainting, or timing issues.

💻

Code from the internet

You found a promising EA but have no idea if it's safe to run live. You need eyes on it before risking capital.

🔄

MT4 → MT5 migration

Your broker switched platforms and your EA won't compile. Logic needs to carry over cleanly.

What Clients Say

★★★★★

"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."

Marco T., Prop Trader, FTMO
★★★★★

"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."

Alex K., Algo Trader
★★★★★

"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."

David R., Systematic Trader
★★★★★

"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."
