With every new update, MetaQuotes continues to strengthen the security framework of MetaTrader 4. After the major changes introduced in build 1420, the release of build 1455 confirms MQL’s long-term strategy: protect intellectual property and reduce the misuse of Expert Advisors (EAs) and indicators.
While these updates aim to create a safer ecosystem, they also bring challenges for traders who rely on older or unlocked tools. Understanding what MetaTrader 4 build 1455 means for your trading environment is essential.
MQL Security and Product Protection
Since build 1420, MQL has tightened protection mechanisms, making it difficult for unlocked EAs and indicators to operate without DLL support. MetaTrader 4 build 1455 continues this direction, closing more loopholes used by modified products.
Many traders prefer non-DLL EAs because they are easier to use and feel more “native” to MT4. However, MQL has now fixed most unprotected products, forcing users to migrate toward official or source-based solutions. As a result, older tools may suddenly stop working after upgrading to build 1455.
The Ongoing Risk of EA Scams
Despite stronger technical protection, MetaTrader 4 build 1455 cannot eliminate common EA scams. Fake trading histories, manipulated performance data, and overhyped products still exist. Traders must remain cautious when choosing automated systems.
Before buying any EA, it is important to:
- Verify real trading results
- Test the EA on a demo account
- Check the developer’s reputation
Security updates protect developers, but critical thinking protects traders.
How to Adapt to MetaTrader 4 Build 1455
There are several practical ways to handle the changes:
- Use official EAs or those with source code updated for new builds
- Choose DLL-based EAs that remain compatible
- Temporarily stay on older builds, understanding brokers may reject them over time
Each option has trade-offs between convenience, safety, and long-term compatibility.
Conclusion
MetaTrader 4 build 1455 reinforces MQL’s commitment to security and product integrity. While it may disrupt older or unlocked tools, it also encourages a healthier trading environment. The safest path forward is to use legitimate EAs from trusted developers and test them carefully. Patience and transparency remain the keys to sustainable automated trading in the modern MT4 ecosystem.
