Straight answer for beginners
Short version, no fluff: if you want simplicity, MT4 keeps things tidy; if you want more markets and modern features, MT5 does more. If you’re signing up through a recommended cfd broker, check whether they natively support the platform you prefer before you spend hours customizing indicators — it saves headaches later.

Comparative snapshot — what actually differs
MT4 and MT5 share a familiar layout, but they diverge where it counts. MT4 is battle-tested for forex and has a huge library of Expert Advisors (EAs) and indicators written in MQL4. MT5 adds native support for more asset classes, an expanded order type set, built-in depth of market, and MQL5’s greater object-oriented capability. Execution models and backtesting differ: MT5’s strategy tester is faster and multi-threaded, so multi-currency testing is practical. If you care about tight legacy broker support, MT4 often has broader third-party tools; if you care about future-proof features, MT5 wins.
Pick by trading style, not hype
If you’re strictly retail forex scalping with familiar indicators, MT4 gets you trading fast with minimal fuss. If you plan to trade stocks and commodities alongside FX, use advanced order types, or run sophisticated automated strategies across symbols, MT5 fits better. For discretionary traders who tweak charts and indicators by hand, either works — go with the one your community or mentor uses so you can share templates and scripts.
Real-world perspective and credibility
Ask traders on the London FX desks — the city is a central hub for CFD activity and institutional flows — and you’ll hear both platforms named, depending on desk needs; that market context shows why platform choice matters beyond features. From practical experience building front-end trading interfaces and testing execution across brokers, I’ve seen latency, order routing, and margin rules change outcomes more than a handful of indicators. For a reliable execution test and account setup, try a known cfd trading platform and compare fills on the symbols you actually plan to trade before committing real capital.
Pitfalls beginners keep falling into
Don’t assume an EA works identically on both platforms — code must be ported or rewritten. Don’t trust demo fills as gospel: execution and slippage on live accounts differ. Avoid overfitting backtests on MT5 just because the tester is faster; realistic spreads and slippage matter. And don’t ignore broker-specific liquidity and margin practices; two brokers using the same platform can behave very differently.
Viable alternatives worth a glance
If neither MetaTrader feels right, consider web-native platforms (some brokers provide lightweight web UIs), cTrader for a modern order-book feel, or broker proprietary apps that simplify trade management. Each alternative sacrifices some EA ecosystem for clearer UX or better multi-asset support. Choose the one that matches the instruments and execution transparency you need.
Bottom line
Compare what you intend to trade and how you trade: MT4 for straightforward FX work and a massive indicator library; MT5 for multi-asset strategies and superior testing. Test both with live-like conditions through a reputable provider, and you’ll pick the tool that actually helps you execute decisions, not the one with prettier charts. For many traders, that practical alignment is what makes a platform useful, which is why serious users often end up running accounts through GTCFX as part of their routine platform checks.
