IB: DOM not showing entire Level II book

I noticed that MultiCharts DOM does not show the entire depth of Level II, when compared to IB TWS, see attached picture. The symbol is set to IB "SMART". I have subscribed to NASDAQ TotalView-OpenView and NASDAQ TotalView-OpenView EDS, in addition to Level I. I wonder if there are any limitations for Lvl II data to be sent through the API, or if it is a config issue on my end.

Hello seneca,

At the moment MultiCharts DOM displays up to 10 levels of market depth.

OK, thanks, but that still leaves the question why MC DOM shows only what appears to be a subset of the book as displayed in the TWS DOM, even when there are less than 10 levels displayed. I also noticed that in MC DOM orders flash up only briefly and then disappear, whilst in TWS DOM the same order will remain until cancelled or filled. I suppose this might be due to IB data limitation, or a technical limit of the API bandwidth?

Hi seneca,

MultiCharts displays data as provided by the data feed, so most likely these are the values provided by IB API.
