Investor Account Copier: Automated MT4 multi-account trade copying for efficient replication

This 2026 Review includes a Performance Analysis of the Investor Account Copier, focusing on replication accuracy, latency, and practical trade management. The Investor Account Copier stands out by specifically supporting investor/read-only master accounts, a common constraint for signal-only sharing, and offers targeted controls to maintain lot ratio fidelity and prevent order duplication across follower accounts. The review highlights its transparent architecture and actionable telemetry, which help diagnose mismatches when symbols or contract sizes differ between brokers. The algorithm works by listening to the master MT4 account trade stream and mapping each execution to configured follower accounts. It supports proportional copying based on balance or equity, fixed-lot overrides, and symbol translation tables to handle differing naming conventions. Investor Account Copier also includes pip offset and slippage mitigation options to tune replication when brokers offer disparate spreads. In practice, the tool handles high-frequency parent strategies with moderate throughput; it is equally effective for low-frequency discretionary masters. Risk management is configurable with maximum concurrent trades, daily loss caps, and per-account trade limits. Expected performance characteristics include minimal missed orders when run on a colocated VPS with stable connectivity, and rapid recovery from temporary disconnections due to its built-in retry and logging mechanisms. Ng Pei Sheng Jay has focused the design on robustness and operational transparency, making Investor Account Copier a practical utility for traders who must reliably mirror read-only master accounts on MT4.
