Authentication to use an .ex4 ea

[DigitalNino]

Hello,

I would like to secure one of my ea in .ex4 so that when I share it the people who would like to use it would have to identify themselves. 

And I would like to make it impossible to decompile it in mq4.

Is this possible and what are the solutions?

There has been zero proof that any ex4/5 can be decompiled since Build 600+ (2014)

Hello

Yes 

Compile it with the cloud compiler . That takes care of one of your issues .

The other, the identification you will need your own server or a licensing API .
