0. Introduction & System Architecture
Understanding Nexus Copier before you start
0.1 What is Nexus Copier?
Nexus Copier is a professional automated trading system that copies signals from Telegram channels directly into MetaTrader 4 and MetaTrader 5, opening, managing, and closing trades without any manual intervention.
It is designed for:
- Signal followers — subscribe to Telegram signal channels and let the system trade automatically.
- Prop firm traders — built-in Stealth Mode hides EA patterns from monitoring systems.
- Multi-account managers — route signals to multiple MT4/MT5 accounts simultaneously with per-account risk settings.
0.2 The 3 Components
EA (Expert Advisor)
Compatible with MetaTrader 4 and MetaTrader 5. Polls Nexus Server for signals and executes trades — opens orders, manages SL/TP, applies grid logic, trailing stops, break even, and protections.
NexusServer
A Windows background service. Connects to Telegram via the official API using your personal account, reads channel messages, parses signal text, and serves the result to the EA via a local HTTP endpoint.
Configurator
A Windows desktop application. Provides a visual interface
to configure all 226+ parameters across tabs. Writes the final config.json
file consumed by NexusServer and the EA.
