How to limit the use of EA I build for my clients?

[BlueMoon]

I would like my EA to work only for DEMO account.

I would like my EA to work only for certain number of days/hours.

I would like my EA to work only once certain key is entered? This key only works once.

How do I accomplish all the above?

Thank you very much. Great help.

I got the Real/Demo thing limit. I also got the time limit. But I still don't understand the key part.
Can you please explain more on this?

I want to send my EA to my client with a key. I do not want my client to be able to distribute or use this EA on more than 1 MT4 instance.

in that case fixly match each EA for each login number:

account number is typed into EA fixly ...
you can also match it to broker name, etc. ..

there are many ways, as remote licenses
you can also do some encryption
but for these you need a lot of custom code and this is probably not what you will do ...

@miro1360 Thank you so much for your reply. But I think I am still missing something here.

I don't think my client would be comfortable to share their real account information with me. Is there any other way to accomplish this? The goal is so that the client can only install it on 1 MT4 instance and that he cannot distribute the EA to anyone else.

think deeper about what you want to do, what is unique thing which your client have - different as other clients ...

it can be hardware ID, but this need custom code to obtain information and again, some programming basics you need know for it ... because here you are working with kernel, etc ...

if you make it only for serial number, this serial number is shareable and all can use your EA ...
try google for some technique how to do it, if you find something, post here
