Why does my EA have a cross next to it when I drag it onto my chart?

It seems you don’t have Expert Advisors enabled on your MT4 terminal. This can be done by simply clicking on the ‘Expert Advisors’ button in the main toolbar above the chart. When the little symbol inside it turns from red to green EAs have been enabled. Alternatively you can do this by going to ‘Tools’, ‘Options’, selecting the ‘Expert Advisors’ tab and ensuring that the ‘Enable Expert Advisors’ box is ticked. To save these changes and return to your chart simply click ‘OK’.
