The three infrastructure layers in retail trading
Most retail traders interact with only two layers: (1) their trading platform (MT4/MT5/cTrader on PC or VPS), and (2) their broker's server. Between them is the public internet — an unmanaged, shared resource that routes packets through whatever path is currently cheapest for network operators. That path is not optimised for trading. The priority route is a dedicated relay node positioned between the other two.
What a VPN does (and why it is wrong for trading)
A VPN encrypts all traffic and routes it through a general-purpose server chosen for privacy, not performance. Result: extra encryption overhead (5–20ms per packet), plus a routing detour through a server rarely near your broker's DC. Total overhead: 10–50ms. For context on where your broker's DC is and why proximity matters, see our broker DC reference.
What a VPS does (and what it does not do)
A VPS moves your trading platform from your home PC to a cloud server. This helps with uptime and 24/7 EA operation. It does not change the network path from that server to your broker's matching engine. A VPS in Frankfurt connecting to LD4 still routes across the public internet.
What a trading proxy does
A SOCKS5 proxy does not run your software. It does not encrypt traffic. It receives your order from MT4 and forwards it directly to the broker's server using a path optimised for that specific destination. TradersProxy nodes are positioned inside or adjacent to the same Equinix facilities as the broker. The node-to-broker hop is 2–8ms.
How to set one up in MT4 or MT5
In MT4: Tools > Options > Server tab > Enable proxy. Enter proxy IP and port. Select SOCKS5. Save and reconnect. Check Help > About to verify the new broker ping. For a detailed walkthrough with screenshots, see our MT4 SOCKS5 setup guide.
