I am trying to download the historical data of this symbol (DAX INDEX) using NinjaTrader7 and the TWS.
I am trying to do this using the symbol DAX (which is located in the default Index list). The symbol map of interactivebrokers for this symbol is DAX|DTB.
I receive an error when I try to download it. Please, can you tell me if I am doing something wrong? Perhaps the symbol map has changed?
Thanks in advance.
