Before buying an EA, many people get stuck on a basic question: MetaTrader 4 or 5? Short answer: for EAs, MT5 is better on nearly every axis, and it's the industry's future. But the actual choice still depends on which platform your desired EA is on.
Core differences (the EA-relevant ones)
| Dimension | MT4 | MT5 |
|---|---|---|
| Backtest engine | Single-thread, limited accuracy | Multi-thread + real-tick backtest, closer to live |
| Assets | Mainly forex | Forex + stocks + futures + crypto |
| Hedging / netting | Hedging only | Both hedging and netting |
| Performance | Older architecture | Faster, more modern |
| Future | No longer actively developed | The vendor's main focus |
Why MT5 is better for EAs
The key is backtesting: MT5's Strategy Tester supports "every tick based on real ticks," the foundation for judging whether an EA is credible (how: tutorial). MT4's backtest accuracy is limited and easily produces a "pretty but unrealistic" curve. MT5's multi-asset, multi-timeframe and performance also suit modern EAs better.
Is MT4 still useful?
Yes. Plenty of long-standing EAs are MT4-only; if the one you want exists only on MT4, use MT4. The platform itself isn't right or wrong — what matters is which platform your EA and its live verification are on.
How we chose
Every EA we sell is MT5 — because MT5's backtest credibility, multi-asset capability and longevity give buyers more assurance. Pick an EA by its strategy and live record first (see verification, do EAs work); MT5 is the platform. All EAs here.
Risk note: the platform is only a tool and does not determine P&L. EAs / algo trading are high risk; past performance does not represent future returns and is not investment advice. Only trade with money you can afford to lose.
