I am using the MT4 Ifc Market for DDE. There are symbol names like # C-BRENT, # S-PFE. Amibroker doesn't see these symbol names. What could be the solution (import wizard don't see to csv and DDE not working)
AmiBroker by itself does NOT treat # character differently than any other letter. You can surely add symbols with # at start using Symbol->New menu.
The mistake you are probably making is trying to use ASCII import to add symbols and put # in the very beginning of the line.
ASCII importer treats # at the beginning of the line as COMMENT and ignores the line.
You should rather use Symbol->New menu, or if you must use ASCII importer, place Symbol in SECOND column if you have symbols that start with #
