My IB dashboard has ES futures June showing values that don't end up in .00 .25 .50 or .75 I'm really referring to ES futures and not ES index (which is also available). Enclosed a snapshot. 2416.60 is Jun futures and 2415.82 is the ES index. I questioned IB about the ES futures and got this answer: Does this make sense ? I thought that any quote of futures or stocks in dashboard were the price of the last executed trade.
Out of curiosity I have to investigate what means "The Dashboard displays the Mark Price, which is coming from the theoretical ticker". I don't know the concept of theoretical ticker in ES. Never heard about it.
I'm curious too. Why would they display something called "theoretical ticker prices" if you can't get buys or fills at that price.
I just learned something new. I never heard of that before. I bet IB didn't put that in their explanation guide to explain their ticker price labeled "ES".
Some who have replied to this thread do not understand the very important difference between MID (halfway b/w NBBO bid and ask) and MARK (a rules-based definition that is dependent on immediate-past market behavior, which in a slow or iliquid market will *not* be even *near* the MID). As well, these definitions are independent of asset choice -- it doesn't matter whether it's a liquid equity, a clunky bond, traded paper, future, index option, etf, whatever.
