I think you have messed up somewhere with the data.
As far as I understand you have downloaded the data from the Forex Historical App, didn’t you? That is the data from Dukascopy. And then you have changed the symbol settings in EA Studio settings to fit the JFD broker? It that correct? If so, then you are alright.
But you have a very small number of strategies generated which makes me think that you have not done it exactly this way.
Please, watch all the videos that are on our Historical data page.
