ameritrade bid/ask size

[stock777]

  Not really a bug, so I'm putting this here.

 

  Ameritrade level 1 does a lousy job of supplying true bid/ask size. Not even close.   Looks like only the primary exchange is shown, but even that is a shaky theory  if you look at the level 2 matrix,

 

 Anything you can do about this (not optimistic, I must say)

we are just showing what is being returned. Not computing it, so nothing we can do.  In general, the Level I bid/ask and bid/ask size are the NBBO, so it would definitely not match up to the total # of orders on the level II at any particular level, and as far as comparing to the top row in Level II, that depends on the selected sorting on L II

 I get that L1 is the nbbo, but by what perverse standard are the orders at the SAME PRICE not aggregated?

 

 So there's 100,000 shares bid on a stock at $5 and Ameritrade, and possibly others, are  showing  8,000?  Who does this help?

 

 It's just wrong, and the actual size on the b/a should be disseminated. I know it has nothing to do with MT, but thought you  might know more about it.

 

 I believe  IB does it right,

NBBO is not aggregated. It is just the best order. Not the total size of all the orders at the price. We don't make the rules

  on the TWS platform IB displays true b/a size.  They must be special

And MT if you use IB as the source?
