The trading platform question seems more complex than it is. For XAUUSD gold trading with automated Expert Advisors, MetaTrader 5 is the only practical choice — not because other platforms are bad, but because the combination of universal broker availability, MQL5 scripting capability, and tick-accurate backtesting creates an ecosystem that no other retail platform replicates. Pro-Scalper EAs are all built natively in MQL5 and run exclusively on MT5.

The MT4 vs MT5 question is worth addressing directly: MT4 is an older platform that many brokers are phasing out. While thousands of legacy EAs exist in MQL4, MT5 offers meaningfully better backtesting (real tick data vs simulated), more order types, and better multi-symbol support. The Goldie Sniper EA PRO and all Pro-Scalper products require MT5 — they will not install or run on MT4.

For the practical question of where to run MT5, a VPS (Virtual Private Server) is the professional answer for any trader who cannot guarantee their personal computer and internet connection will remain active 24/5. The London session open at 8:00 AM London time and NY open at 8:30 AM EST are the highest-priority windows for session EAs — missing these windows because your computer was restarting or your internet dropped is avoidable. A quality VPS with a data center physically close to your broker's server adds low latency as a secondary benefit, reducing the time between EA signal generation and order execution.
