MetaQuotes, the fintech company behind the widely used MetaTrader 5 (MT5) trading platform, is set to release build 5120 on Friday. This latest version delivers a wave of improvements aimed at refining user experience, strengthening code management, and enhancing platform stability.
Key Enhancements in MT5 Build 5120
MetaQuotes has packed build 5120 with technical upgrades that address long-standing user feedback while introducing more developer-friendly functionalities.
Improved Update Mechanism for Terminal
The update process has become more intelligent. In previous builds, updating the MT5 terminal would overwrite the entire MQL5 Standard Library. With build 5120, only modified files will be replaced, reducing unnecessary changes and preserving user customizations.
Full-Screen Mode Behavior Refined
The terminal will now automatically reset full-screen view mode upon restart. This ensures the full interface is always visible at launch, which is particularly beneficial for traders who switch between different display setups or devices.
MQL5 Language Enhancements
Build 5120 introduces greater flexibility for developers working with arrays and data conversion. The following functions now support the passing of arrays with signed and unsigned typecasting:
- ArraySwap
- WebRequest
- CryptEncode
- CryptDecode
- StringToCharArray
- CharArrayToString
- StringToShortArray
- ShortArrayToString
- StructToCharArray
- CharArrayToStruct
These updates are especially valuable for complex algorithmic trading strategies and data encryption tasks.
MetaEditor, the integrated development environment (IDE) for MT5, also receives meaningful updates:
- AI Assistant Expansion: Developers now have access to more advanced AI models, including GPT-4.1 and 04-mini, allowing for smarter code suggestions and debugging assistance.
- Stricter File Verification in MQL5 Storage: File hashes are now used to verify local changes accurately. This prevents misleading indicators (such as false red icons) for files that have not truly been altered from their repository versions.
Conclusion
Build 5120 marks another step forward in MetaQuotes commitment to refining the MT5 platform for traders and developers. With smarter updates, better coding tools, and expanded AI integration, MT5 continues to cement its place as a leading platform in the algorithmic and retail trading space.
