MetaTrader 4 Is Dying, and Your Broker Might Not Have Warned You
MetaTrader 4's official lifecycle is ending. Most brokers have stopped issuing new MT4 accounts. Some are already locking traders out. And thousands of Expert Advisors running on MT4 right now will just stop working the day your broker pulls the plug.
The problem: 60% of traders who try to migrate their MT4 EAs to MT5 themselves end up with broken bots, lost capital, or both.
The Migration Myth: "We'll Just Move It Over"
Most traders think EA migration is simple. Export from MT4, import to MT5, it works. Done.
That's wrong.
MT4 and MT5 are fundamentally different platforms. The code is incompatible. The order-handling system is different. The data feeds are different. The risk management model is different. Moving an EA from MT4 to MT5 isn't a copy-paste job—it's a complete rebuild.
Traders who don't understand this are about to lose everything.
- Your MT4 EA will not automatically work on MT5
- Your broker's "migration tools" handle account data, not EA code
- The best strategy on MT4 can blow your account on MT5 if the migration is wrong
Why 60% of DIY Migrations Fail
Here's what breaks when traders try to migrate alone:
- Incomplete code conversion. MT4 functions don't have 1:1 equivalents in MT5. Traders who don't know this skip critical logic without realizing it.
- Backtesting assumptions break. Your MT4 EA was backtested on MT4 data using MT4 execution. MT5 backtests differently. Same EA, same data, different results. Traders assume the backtest is valid and go live—then watch the EA fail in real trading.
- Execution model changed. MT5 uses a different market model. Orders execute differently. Latency behavior is different. Slippage patterns are different. An EA profitable on MT4 can turn into a drawdown machine on MT5.
- Risk management doesn't translate. How EAs calculate margin, manage position sizing, and handle stop losses is completely different. A strategy that protected capital on MT4 can over-leverage on MT5.
- Symbol mismatches cause silent failures. Your broker's MT4 feed had different symbols or decimal places than MT5. The EA tries to place orders on symbols that don't exist. Orders fail silently.
Most traders don't find these problems until they're live with real money. By then, the losses are real.
The Cost: A Dead EA and Lost Capital
When a DIY migration breaks, you lose more than the EA.
You lose every hour tuning the original strategy. You lose the backtest data. You lose months of live trading history that proved it worked. You lose the confidence to trade manually while you figure out what went wrong. And if the broken EA trades live, you lose capital.
The real cost of a botched migration isn't the technical fix. It's the opportunity cost of a dead EA while you scramble to rebuild or find a solution.
Traders often take 3-6 months to rebuild a broken EA from scratch. During that time, the strategy sits dormant. The market moves on. The conditions that made the EA profitable might have changed. By the time the new EA is ready, the window has closed.
Your Broker Is Setting a Deadline
You don't have infinite time. MetaQuotes has officially announced MT4's lifecycle end. Major brokers are setting cutoff dates. Some have already started locking MT4 accounts or forcing migration to MT5.
The trader who migrates early has weeks to test and adjust. The trader who waits until the final month? They're rushed. Rushed migrations have higher error rates. Higher error rates mean broken EAs. Broken EAs mean losses.
Here's your timeline:
- Now (ideal): Get a professional migration done, backtest thoroughly, deploy to demo for 2 weeks, then go live with confidence.
- Next month (risky): DIY migration or cheap developer, backtest quickly, deploy with fingers crossed.
- Month before cutoff (catastrophic): Your broker turns off MT4. Your EA stops. You have zero options except manual trading or abandoning the strategy.
How Professional Migrations Actually Work
A proper EA migration doesn't mean rewriting from scratch. It means understanding your original EA's logic, rebuilding it in MT5 architecture, and validating that it trades the same way (or better) on the new platform.
The process:
- You provide your MT4 EA. We analyze the logic and identify critical components.
- We rebuild the EA in MT5, preserving your original strategy while adapting it to MT5's execution model.
- We backtest on historical MT5 data and walk-forward test to ensure consistent performance.
- We deploy to your broker's demo account and run live tests under real market conditions.
- We deliver the completed MT5 EA with a full backtest report showing side-by-side comparison (MT4 original vs MT5 rebuilt).
You can see exactly how the EA trades before risking real money. Most traders are ready to go live within a week.
This is what Alorny does. From $150 for simple EA conversions, we rebuild your strategy on MT5. More complex strategies (ICT, SMC, AI-driven logic) cost more. We quote based on your EA's complexity, not a guess.
The Price of Action vs. The Price of Inaction
A professional MT4-to-MT5 migration costs $150-$400 depending on EA complexity. That sounds like money.
But consider the alternative: a dead EA costs you everything it would have made in the future. A blown account from a bad DIY migration costs your capital. Months spent rebuilding? That's opportunity cost you'll never get back.
The real question isn't whether you can afford a professional migration. It's whether you can afford NOT to.
The trader who pays $200 to migrate now is protected. The trader who waits or tries DIY is betting their profits on a platform architecture they don't understand.
Your Migration Timeline
Do this:
- This week: Check your broker's MT4 support status. Ask if there's a sunset date. Most have one.
- This month: Get your MT4 EA migration plan in place. Either DIY (if you know MQL5 inside and out) or hire a professional. Budget 1-2 weeks for testing.
- Before the cutoff: Deploy the migrated EA to demo, verify it works, then go live.
Tell us what you trade and we'll quote a migration price within 24 hours. We handle the technical work. You keep your strategy running.
Key Takeaways
- MT4 support is ending. Your broker will shut it down. Your EA will stop working.
- DIY migrations fail 60% of the time because the platforms are fundamentally different.
- A professional migration costs $150-400. A dead EA costs you all future profits.
- Start the migration now while your broker still supports MT4. It's easier and faster.
- The cost of inaction is guaranteed. The cost of migration is one-time.
