MT4 brokers with non-expiring demos

I am looking for MT4 brokers with non-expiring demos. I found a list online but a few that I have tried have expiring demos even as short as 14 days and some others demand you open a real account or run really annoying mt4 web platforms.

Purple trading runs non-expiring ones but they don't open an account for clients in my country, so I need to find a few and ask. Any one knows a good one?

ALpari, Axiory, CMC markets and FXCM.

Dukascopy has something called a "extended validity demo." The company is Swiss regulated.
The demo account will work indefinitely, as long as you trade at least once every 14 days I think.
