LicenseShield by barmenteros FX provides MT4 license protection for any MetaTrader Expert Advisor, indicator, or script. Copy-paste our compiled MQL library, add 3 lines of code, and your software is protected from piracy — no servers, no backend, no DevOps required.

The Problem: Piracy, Spreadsheets, and Trial Abuse
Your trading software appears on pirate forums within days of release. Every unauthorized copy is a lost sale. Manual license tracking in spreadsheets breaks down after 10+ customers. And without a proper trial system, offering risk-free demos means risking abuse.
LicenseShield solves all three problems with a single integration.
Add License Protection in 3 Lines
Copy-paste our compiled MQL library and add just 3 lines to any MQL4 or MQL5 program — EA, indicator, or script.
#include <LicenseShield.mqh>
int OnInit() {
if(!LicenseShield_Verify("YOUR_API_KEY")) return INIT_FAILED;
return INIT_SUCCEEDED;
}The verification call takes less than 100ms. Your software checks the license on every launch — if it’s not valid, it stops running. If you’re new to EAs, learn about Expert Advisors and how they work before getting started.

Built by the Team Behind 200+ MetaTrader Applications
LicenseShield is developed and maintained in-house by barmenteros FX — the same team that has been building production MetaTrader systems since 2011. We built LicenseShield because our own clients needed reliable license protection, and nothing on the market delivered it without requiring backend knowledge. Every feature exists because a real EA developer needed it.

Frequently Asked Questions
Does LicenseShield work with both MT4 and MT5?
Yes. LicenseShield provides compiled libraries for both MQL4 (.ex4) and MQL5 (.ex5). The integration code is identical for both platforms — same 3-line implementation, same API, same dashboard. It works with Expert Advisors, indicators, scripts, and libraries on either platform.
What happens if your servers go down?
LicenseShield runs on AWS infrastructure with automatic failover. In the unlikely event of an outage, the verification function returns a configurable default response — your EA won’t stop working because of a momentary connectivity issue. We maintain 99.9%+ uptime.
Can I try LicenseShield before paying?
Yes. The Free plan includes 10 verifications per day and 1 active license — enough to test the full integration workflow in your development environment. No credit card required. Upgrade to a paid plan when you’re ready to scale.
How long does integration take?
Under 10 minutes. Download the compiled library, add it to your MetaTrader Libraries folder, copy 3 lines into your OnInit() function, and paste your API key. No server setup, no backend knowledge, no additional dependencies. For a detailed walkthrough, see our license verification tutorial.
Is LicenseShield developed and maintained by your team?
Yes. LicenseShield is built entirely in-house by barmenteros FX — the same team providing MetaTrader programming services since 2011. We control the full stack: API, dashboard, compiled libraries, infrastructure, and billing. No third-party dependencies.
