How to Protect EA from Decompilation

One of the biggest concerns for developers selling Expert Advisors (EAs) and indicators on the MQL5 Market is the risk of decompilation. Despite the platform’s official claims of security, hundreds of cracked EAs and indicators from MQL5.com are freely circulating on the internet — making it clear that the platform alone does not offer sufficient protection against piracy or reverse engineering.

Why MQL5.com Protection Is Not Enough

When you compile your EA into an .ex5 file and publish it on MQL5.com, you're assuming that the proprietary logic inside the compiled code is secure. Unfortunately, that's not the case. Decompilation tools and experienced hackers can reverse-engineer .ex5 files, exposing your intellectual property. Once your EA is cracked, it can be:

• Resold illegally

• Distributed for free on pirate forums

• Modified and used without attribution or license

This is not just a theoretical risk — it’s a widespread reality in the trading software community.

The Best Way to Protect Your EA

If you're serious about securing your EA from decompilation, the traditional methods are no longer enough. Instead, you need a hybrid protection system — and that's exactly what FXPIP.ONE offers.

At FXPIP.ONE, we use a server-side protection system where over 50% of the EA logic is written in C++ and hosted on our secure server. The client-side .ex5 file only contains a minimal interface — just enough to interact with the server and display the results.

Benefits of the FXPIP.ONE Protection System:

• No full logic in .ex5 file – makes reverse engineering useless.

• Server-side calculations in C++ – adds an extra layer of obfuscation and speed.

• Real-time license verification – only licensed users can access server logic.

• Tamper-proof protection – even if the client file is extracted, it cannot operate without server communication.

This model makes it virtually impossible to crack or resell your EA, because the core functionality simply doesn’t exist on the client machine.
