I have several Excel sheets that utilize the DDE data from MT4. I am unable to update my sheets. They just stall and have to be terminated. I tried the MT4 DDE Excel example and it would not update. Same results. I tested with codersguru's DDE client and another DDE client. They both are successful in reading the DDE data. I think the problem may be with Excel, some automatic security update or some system setting but I have not yet found a solution. Has anyone else run into a similar problem? I suspect that the solution is simple but it eludes me. Please help.
