MetaTrader Automation

Sophisticated engineering for the world's most popular FX platforms.

The Problem

Retail MT4/MT5 Expert Advisors are notoriously unstable. They suffer from memory leaks, fail to handle disconnects gracefully, and lack the sophisticated risk-management controls required by institutional capital or prop-firm challenges. Furthermore, legacy MQL4 code is often poorly documented and difficult to maintain or scale.

Our Approach

We build Expert Advisors as enterprise software. Our MQL5 and MQL4 systems feature modular architectures, exhaustive error handling (OrderSend retries, requote management), and strict memory management. We embed hard-coded equity protections directly into the execution logic to ensure prop-firm compliance and capital preservation.

Tech Stack & Capabilities

  • MQL4 to MQL5 Migration: Secure porting of legacy MT4 EAs into fully optimized, object-oriented MT5 code for faster backtesting and execution.
  • FIX API Bridging: Custom C++ bridges that route MetaTrader signals to institutional FIX API gateways with sub-millisecond latency.
  • Prop Firm Automation: Hard-coded risk management engines designed to strictly enforce daily drawdown limits and exposure constraints.

Frequently Asked Questions

Can you decompile an existing .ex4 or .ex5 file?

No. We only work with the original .mq4 or .mq5 source code to ensure structural integrity and compliance with IP laws.

How do you handle VPS disconnects?

Our systems use state-recovery logic via GlobalVariables or local CSV logging. If a terminal restarts, the EA instantly recognizes its open positions, magical numbers, and ticket states without double-executing.

Do you guarantee passing prop firm challenges?

No. We guarantee that the software will execute your strategy's logic flawlessly and respect your hard-coded risk limits. Alpha generation depends entirely on the strategy's statistical edge.
