1 activation per VPS/computer
on that VPS/PC unlimited accounts
Install the EA on every instance on MT4 on your server. It doesn't matter how many MT4 platforms you have on your VPS.
Use any number on MT4 on that server, it will count as only 1 activation.
Use it on your desktop, it will be the second activation ... use as many accounts (MT4) on your desktop.
Use it on your Laptop, it will be the third activation ... use as many accounts (MT4) on your laptop.
Thank you for your help ... so far that's clear and I've applied the hadvices, very helpful.
Now my VPS grew and another MQL5 user wants to use one of his EAs on my VPS. Is that possible? One VPS, both under the same windows account, two mql5 accounts though and their respective EAs? Each mql5 user in his respective separate data directory/program directory.
