I spoke about EA Studio. I said, the “Metatrader-Demo” data history from it was not updated since 16.02. There is a few days missing data informations (at least in H1). But anyway, I clarified all with Mr. Popov, it was a system error .
And he also shared to me that “MetaTrader-demo” source will be available for only 1 more month. Later, will be only the “Premium Data” source available.
