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.
I restarted TWS, and finally got 10 or so level of Depth in Booktrader. It seems that the book is an aggregate one( with SMART ) with all ECNs showing their sizes, which make it somewhat confusing... Does equity scalpers trade with this kind of aggregate book or is it possible to trade with just ARCA or BATS book? Thanlks a lot.
