Question: My cTrader Demo account is deleted. Why is that?
Each brokers may have setup expiration dates for Demo accounts. It can be 7, 15, 30 days or more, after the last activity.
To keep your Demo account semi-permanently, you need to login at least once during the period.
Or a broker may be able to clear out the limitation if you request for that.
You can also create a Demo account directly from Spotware which has no expiration dates, but it wouldn’t have the same trading conditions as your broker’s Demo account.
