Allow DLL imports is quite clear to me and i use it every day for calling external API functions, but what on earth is “Allow import of external experts”? Is this a translation error and in reality means .ex4 libraries? Or is there really a way to have an EA import another EA and call it's start function (and let it trade in parallel as if it where alone on the chart)? I haven't found the answer to this anywhere in the documentation, but i doubt that this is possible.
