License Manager EA

This EA uses a license panel system to verify usage before running trading logic.

File Placement

• Place LICENSE_SINGLE.mqh in the same folder as your EA .mq5 file.
• If using a subfolder, update the #include path in the EA file.

Integration Steps

1. Include the License File
   #include "LICENSE_SINGLE.mqh"
2. Initialization (OnInit)
   Call the license check when the EA starts:
   VerifyLicense();
3. Deinitialization (OnDeinit)
   Clean up license resources when EA is removed:
   HandleLicenseOnDeinit();
4. Chart Event Handling (OnChartEvent)
   Pass chart events to the license panel:
   HandleLicenseOnChartEvent(id, lparam, dparam, sparam);
5. Tick Validation (OnTick)
   Check license status on every tick before executing trading logic:
   if(!HandleLicenseOnTick()) { Print("License is not valid — removing EA from chart."); return; }
6. Optional Timer Validation (OnTimer)
   Periodically re-check the license if using timers:
   if(!HandleLicenseOnTimer()) { Print("License is not valid — removing EA from chart."); IsLicenseValid = false; }
