MT5 Build 5120 Brings Smarter AI Support and Better Updates
MetaQuotes has released MetaTrader 5 (MT5) build 5120. It brings targeted improvements in the trading terminal, MQL5 programming environment, and MetaEditor.
Platform Enhancements
Update Mechanism Improvement
The platform updates more efficiently post updates. MT5 will only overwrite changed files instead of replacing the entire MQL5 Standard Library during an update. It reduces update time and preserves custom modifications.
Full-Screen Mode Behavior
MT5 will automatically exit full-screen mode on restart. The complete user interface will appear every time the application launches. It will ensure better usability across sessions.
MQL5 Function Upgrades
Support for Array Typecasting
MT5 build 5120 lets developers pass arrays with signed or unsigned typecasting across various functions. It enables more flexible and accurate data handling. The affected functions include:
- ArraySwap
- WebRequest
- CryptEncode / CryptDecode
- StringToCharArray / CharArrayToString
- StringToShortArray / ShortArrayToString
- StructToCharArray / CharArrayToStruct
MetaEditor Updates
AI Assistant Model Expansion
MetaEditor supports GPT-4.1 and 04-mini models in the AI Assistant. It lets traders and developers access advanced language model capabilities while working on the platform.
Enhanced File Verification in MQL5 Storage
MetaEditor introduces stricter file status checks. File hashes will be verified to detect actual changes. It will prevent incorrect red warning icons from appearing when local files match the repository version.
Benefits for traders
These updates will offer these benefits:
Faster and Safer Platform Updates
Traders will not need to wait for the entire MQL5 library to reload during updates. Only changed files are replaced. Quicker updates and reduced risk of losing custom modifications.
Better Startup Experience
The platform will reset full-screen mode on restart. It ensures the full interface is visible every time.
More Reliable Custom Scripts and Tools
With support for signed and unsigned array typecasting in key MQL5 functions, custom indicators, EAs, and scripts can now handle more complex data types more accurately. It reduces errors during execution.
Smarter AI Assistance in MetaEditor
Developers using AI Assistant in MetaEditor can work with updated GPT-4.1 and 04-mini models. It may help generate more precise code suggestions, saving time in strategy development.
Fewer False File Alerts in MetaEditor
File hash verification ensures only genuinely modified files show status changes. It reduces unnecessary confusion or version control errors.
