I am setting up some spreads to watch for adjustments over the next few days in my IB TWS Mosaic Watchlist/Monitor, and I am having issues with the Generic Combo > Pair or Leg-by-Leg function. Specifically, I am trying to set up a condor for SPX June 16 2016 expiration with 2090-2080-1950-1930 strikes, but the 1930 strike is missing from the chain. There are quite a few other options that I have an open position in that is not showing up in the chain as well. Coincidentally, the IB Support Live Chat - which might be the least helpful customer service I have ever experienced - is currently down for maintenance, so I cannot get help directly from IB at this time. Any suggestions?
