Discover how to migrate from MT4 to MT5 while keeping your trusty legacy EAs running. Learn how Copygram bridges the gap, executes trades on MT5 with your MT4 strategies, and future-proofs your trading—all without code rewrites. Actionable migration steps included.
🚦 The MT4 to MT5 Dilemma: Why Is Everyone Talking About Migrating?
MetaQuotes—the developer behind both MetaTrader 4 (MT4) and MetaTrader 5 (MT5)—has unmistakably signaled the industry's future: MT5 is the new standard. MT4, with its legendary simplicity and vast Expert Advisor ecosystem, still powers millions of trading strategies worldwide. But what happens as brokers and platforms accelerate the shift to MT5 only?
MT4 updates and technical support are sunsetting.
MT5 offers better performance, more advanced order types, superior analytics, and cross-platform compatibility.
Increasing broker pressure and regulatory guidelines mean legacy support is shrinking fast.
Upgrading isn’t optional for much longer—but abandoning your trusted EAs and trading systems isn't either. Is there a way to bridge the gap without rewriting years of code?

Legacy trading strategies are at risk without the right migration plan. But bridging the gap doesn't have to break your workflow or your edge.
🦾 The Anatomy of Legacy EAs: What’s Really at Stake?
For many traders, Expert Advisors (EAs) on MT4 are the product of years of development, backtesting, and refinement. Migrating isn’t simple because:
MT4 EAs are coded in MQL4; MT5 uses MQL5, a different language and structure.
Strategy conversion can be costly, time-consuming, and risk breaking profitable logic.
Third-party auto-conversion tools often fail to deliver true compatibility—tweaks and debugging are always necessary.
Some technical indicators and order management principles differ dramatically between the two platforms.
Losing trust in your system—or having to "babysit" a rewritten EA—can undermine trader confidence and edge. That’s why many hesitate, hoping for another way.

Upgrading means more than just new features—it's about safeguarding your edge without losing years of development.

❓ Frequently Asked Questions: MT4-MT5 Migration, Trade Copying & Copygram
Q: Can I use my MT4 EA directly on an MT5 account?
A: Not natively. MQL4 and MQL5 have different architectures, so direct execution isn't possible—but trade copying platforms like Copygram make it seamless with a bridge approach.
Q: Does Copygram introduce any delays or slippage?
A: Copygram is engineered for ultra-low latency using direct broker APIs and is ideal for most trading styles. However, high-frequency strategies or heavy news scalping should always monitor fills and latency.
Q: Is my trading data and algorithm secure?
A: Yes. Copygram never requires access to your EA code or private trading logic—only trade signals for copying. Security is always top priority.
Q: Can I copy from MT4 to multiple MT5 brokers/accounts at once?
A: Absolutely—diversification and multi-account deployment are core Copygram features.
Q: How is this different from MetaQuotes’ built-in migration tools?
A: Platform-native tools often require re-coding. Copygram preserves your existing logic, workflow, and performance with zero risk of codebase breakage.
