MT5 Infrastructure
A low-latency infrastructure connecting quantitative Python trading pipelines to MetaTrader 5 terminals, featuring memory-mapped IPC, automatic order routing, and failover management.
Launch Specifications
Product Overview
MT5 Infrastructure provides a fast, resilient bridge for algorithmic execution. It routes orders from Python decision containers into the MetaTrader terminal in microseconds, maintaining detailed logs of price data and system health.
- Memory-mapped files for low-latency IPC.
- Automatic connection retry and socket loops.
- Detailed price logs and execution logging.
- Full Docker sandbox for isolated backtesting.
What MT5 Infrastructure Can Generate
Passing signals via shared memory.
Logging price changes inside Redis arrays.
Immediate order cancelation on connection loss.
Handling orders across multiple terminals.
The Problem
Standard quantitative trading setups suffer from high latency and disconnected interfaces. Standard socket protocols add milliseconds of execution slippage, leading to poor fills.
Our Solution
A C++ execution wrapper linked to Python via shared memory channels, delivering orders to MT5 within 800 microseconds and monitoring real-time price changes.
Technical Architecture
The infrastructure utilizes Python for research and signals, passing order data through C++ structures mapped to memory files. These memory channels link directly to MetaTrader 5 DLL layers, bypassing network stacks.

Key Engineering Challenges
- •Eliminating memory leaks under rapid price tick streams (100 ticks/sec).
- •Handling connection disconnects without leaving open, unmanaged risk.
- •Synchronizing server times with broker execution timestamps.
Key Lessons Learned
- ✓Memory mapping is 12x faster than TCP sockets for local script messaging.
- ✓Keeping order execution status stateless allows faster recovery from socket drops.
- ✓Explicitly monitoring thread lock metrics prevents deadlock conditions during trading hours.
