MetaTrader 4 and MetaTrader 5 are both built by MetaQuotes, but they are different platforms with different languages, testers and capabilities. Here is how they compare for anyone building or running an Expert Advisor.
| Aspect | MetaTrader 4 | MetaTrader 5 |
|---|---|---|
| Programming language | MQL4 | MQL5 (object-oriented) |
| Strategy tester | Single-threaded | Multi-threaded, multi-currency |
| Timeframes | 9 | 21 |
| Order/position model | Hedging only | Netting and hedging |
| Market depth (DOM) | No | Yes |
| Economic calendar | No (add-on) | Built in |
| Best for | Legacy forex/gold EAs | Modern multi-asset automation |
For backtesting and optimisation, MT5 is significantly faster thanks to its multi-threaded, multi-currency Strategy Tester — a real advantage when tuning parameters across years of data. For live execution both platforms are reliable; latency depends far more on your broker and VPS than on the platform itself.
Choose MT4 if your broker is MT4-first, you rely on existing MT4 EAs/indicators, or your strategy is a classic single-symbol forex or gold system.
Choose MT5 if you want faster optimisation, multi-symbol or portfolio automation, native news handling, or you plan to trade stocks and futures alongside forex.
For brand-new automation projects, MT5 is usually the smarter long-term choice. If you are tied to an MT4 broker or a proven MT4 EA, MT4 remains perfectly capable. Zefinx develops natively for both and can port an MT4 EA to MT5 when you are ready.
