Hello, I am trying to make my first few trades on stocks with booktrader and I have a problem. I just got one level of depth. Let's say I choose MSFT( SMART ) in booktrader, I get one level of depth( bid and ask ). If I choose MarketDepth, I get 5 level of depth. if I choose MSFT@ARCA for example, I have a message saying I cannot trade this security( although I just made a "SMART" trade with booktrader???). I subscribed to Nasdaq TotalView and ARCABook. How can I have those 5 level of depth in booktrader? Also, I don't really know much about equities... When you trade with ARCABook, I think you only have arca sizes displayed...Am I right? Thanks a lot.
