Why MT4 Is Still the #1 Forex Platform
Despite being launched in 2005, MetaTrader 4 (MT4) remains the most widely used forex trading platform in the world. Its popularity comes down to three things: reliability, a massive library of Expert Advisors (EAs), and widespread broker support.
If you're running automated trading strategies, back-testing systems, or just want a battle-tested platform with a huge community — MT4 is still the gold standard.
What to Look for in an MT4 Broker
- Fast execution — Slippage kills EA strategies. Look for ECN/STP brokers with sub-10ms execution.
- Low spreads — EA strategies are often sensitive to spread costs.
- EA-friendly policies — Some brokers restrict scalping or HFT bots. Check their terms.
- VPS support — Many MT4 brokers offer free or discounted VPS hosting for EAs.
- Regulation — FCA or equivalent for peace of mind.
