Thank you for contacting Fusion Markets.
Sorry for the inconvenience.
But a demo account will only last for 30 days, now if you want unlimited length account as soon as you open a live account it will be extended for you. What you will need to do is open a live account then contact us here in customer success and we will set that to not expire so you can continually practice! You can also open up to 5 demo accounts in the Client Hub as you want.
I hope this answers your questions, If you have any other concerns please let me know.
Have a great day and Happy Trading!
