I understand concern. At the moment, there is an upgrade being done on the MT5 synthetics and Multiplier Synthetics, for both real and demo accounts. This upgrade will end on the 30th/September, and you can trade on synthetics again on 1st October
This upgrade is on all our Europian based clients with MLT & MX account broker codes
You will be sent an email on that date regarding these changes and what is to be changed. This is email will be sent to all our users
