I have been working with this future for a long time without problems.
Today, when I started NinjaTrader + IB I received the next message: Error in requesting historical data from IB: The contract description specified for DAX is abiguous; you must specify the multiplier. (200).
This set up was working properly the last week. I am using NT: 7.0.1000.29 and TWS: 944.3
I attach the symbol map of DAX.
Has been made any change on this future?
I reinstalled NT but the error still continues.
Thank you in advance.
