How to prevent metatrader to run several times

New comment
 

dear friends

any one know how to prevent metatrader from running several times

from diffirent directories for one account number

and the login and password are saved in the config directory ?

 

Usually i am installing MetaTraders in different directories and having one demo account per Metatrader + some charts opened with EAs to recognize "which one is opened" easy.

 

thanks fro relpy newdigital but

thanks foe reply.yes i know that ,however

if you are selling indicators or ea to a client

he can copy the meta directory many times and has as many copies as he want

as long as the account details is saved in the config file

i just want to know how to preven this

there is nothing in mql langauge to stop that

i need to know how to do it

thanks

I am not sure about indicators but you may set your EA (to sell as ex4 file) to use in particular one account only. And your clients will get ex4 file ready to use with one Metatrader account.
