I have a general question to the working mechanism of instrument mapping within NinjaTrader. My broker is IB, so to get correct instrument mapping to IB is my main issue. However, I would like to understand the concept behind instrument mapping in general.
I had several problem trading the US energies over the last couple of days (got no trades, got trades without stops, etc.), but this seems to be solved now with changing the symbol of IB from e.g. NG to NG||||1. For some reason my database did not include that and I had no clue of doing that.
Today in the morning I didn't get trades for the DAX and SMI Future. Again the reason seems to be something with instrument settings, because my executions tab shows wrong contract names (FDAX 3-11 & FSMI 3-11), which IB does not recognize. The settings with IB are DAX & SMI but for some reason this gets mixed up, probably with the name of the master instrument.
I have already written an email to support, but I decided to write it in here, because this seems to be a general issue and could be of interest to the whole NT community.
Thx,
Peter
