Summary: Based on 2020-2026 search data, these are the top 10 MetaTrader frustrations: login errors, slippage, margin calls, Mac compatibility, and more. Each problem includes a fix.




Problem 1: Invalid Account Error (Login Failed)
This is the #1 search trend. It means your credentials are wrong or server mismatch.
*Fix:* Double-check account number, password (case-sensitive), and server name. Ensure you use MT4 for MT4 accounts – MT4 and MT5 are not compatible [citation:1].

Problem 2: Chart Time Doesn't Match Local Time
MT4/MT5 use GMT+2 or GMT+3 (with DST). Asian traders often see a 5-6 hour difference.
*Fix:* This is normal. You cannot change server time. Use the Market Watch window for actual price times [citation:1].

Problem 3: Slippage and Order Rejection
Slippage occurs when price moves between order placement and execution. High searches during news events.
*Fix:* Accept normal slippage (0-3 pips). Avoid trading during major news (NFP, FOMC). Use "Execution" tab to set allowed slippage in pips [citation:1][citation:3].

Problem 4: Margin Call & Stop Out
When equity falls below required margin: Margin Call at 100%, Stop Out at 20% (broker-dependent).
*Fix:* Close losing positions or add funds. Check margin level in Trade tab. Stop Out closes largest position by floating loss [citation:3].

Problem 5: MT5 Hedging – Is It Supported?
Yes. Many traders search "MT5 does not allow hedging" – but it does.
*Fix:* You must select "Hedging" account type when opening the account. Open a demo first to verify [citation:1].

Problem 6: DLL Error When Installing EA
" DLL call is not allowed" appears when EA uses external libraries.
*Fix:* Tools > Options > Expert Advisors > Check "Allow DLL imports". For extra safety, also check "Allow live trading" [citation:1].

Problem 7: How to See Spreads in MT4/MT5
Spreads are not shown by default on charts.
*Fix:* Right-click Market Watch window > Columns > Check "Spread". Spread appears as the last column. Lower spreads = lower cost [citation:3].

Problem 8: Leverage Change Request
You cannot change leverage inside MT4/MT5 – this is a common confusion.
*Fix:* Log into your broker's client portal. Find "Account Settings" or "Leverage Change". Submit request. Restart MT4/MT5 [citation:3].

Problem 9: Mac Compatibility & Crashes
Native MT4/MT5 does not exist for macOS. Using Wine or virtual machines causes crashes.
*Fix:* Use MetaTrader's official Mac version (limited). Best: Run Windows via Boot Camp or use a VPS with Windows OS.

Problem 10: Demo Account Creation
Search spike: "how to get MT4 demo without broker".
*Fix:* Inside MT4, File > Open an Account > Select "Demo" server (e.g., "MetaQuotes-Demo"). Fill form. Instant demo, no broker required [citation:1].
