Export live quotes from MT4 to excel



I have been using the 'MT4'|bid!GBPUSD. command in excel and it exports live quotes from my Mt4 platform and it works perfectly if the name of the symbol includes numbers, letters and a dot ( . ) or a combination of the three. 

I want to be able to extract quotes when the symbols also include - (  brnt-mar19) or _  ( dax_30). With the command above the symbols that include - or _ do not export quotes. 

Any suggestions on how to work around this issue?
