may i kindly suggest that IB should stop creating new mess and try to fix the old problems instead..unless you like this public humiliation.. here is an example. ticker ACFN,today's data-
FYI, this does not avoid the margin checking, since you would be making your order more aggressive, which means more margin would be required for opening orders, or less cash would be received for closing orders (both mean the system needs to check the margin again).
the problem is very simple and should be very easy to fix. i've been talking about it for years. here,on ET. the data from certain market centers for certain stocks displayed without multiplicator(or whatever you call it). is it's so hard to fix it? all those tape readers probably having hard time with this one
Isn't that a brokerage dependent thing, whether or not the systems actually recalculate margins on changes in resting orders? But your point is a good one. So I was really wrong by saying "theoretically" it removes the need for margin checking. Actually, "theoretically" there is always a need for margin checking, but in a practical situation I really doubt that this happens on a price bump. But, again, probably brokerage dependent just how closely they choose to calculate required margins.
It is quite likely that the calculation formula used by IB is more sophisticated than we think. Order type and its special fields may be factored into the excessive messaging calculations. It would be sensible for instance to exempt all actions performed on hidden non-native orders (i.e. those which reside on IB servers, such as GLOBEX 'hidden' orders, simulated by the broker's system, because this exchange does not support hidden orders natively). There may be possibly a similar 'exemption' from this formula for odd-lot stock orders, as long as they are excluded by exchanges from their Volume Ratios calculations (just like they are missing from the market volume) or as long as they are again simulated by the broker's system and submitted only once marketable. It would be nice to get a confirmation or denial of that theory from IBj, so that some of us who do not need to 'scalp' the spread could permanently switch to exchange-bandwidth-saving non-native 'hidden' orders (which will fail to execute inside the bid/ask spread, so no 'scalping' with those - at least not for customers, because Spread Trader orders seem to manage to do precisely that - but that may be only due to internalization
You are 100% correct and this is an embarrassment at best. This makes block trade monitoring via a SMART line IMPOSSIBLE. How this has been allowed to persist for so long defies an explanation. I wonder how with THOUSANDS of users this can happen, and the fix is freaking TRIVIAL. I believe this also can misrepresent the size available to trade, though that may or may not have been fixed. The trade size is still bogus.
Remember how long they have resisted providing you the opening quote? Well, I'd rate this volume display 'bug' as a minor inconvenience (on par with the separation of size and price events or the 1 Hz downsampling of charts and price history, or the 10 Hz downsampling of the 10 GHz market data feed). Because only the displayed size got aggregated / obscured, and at least they haven't increased your order size 100 times post-submission (on server side).. And haven't told you that such 'bugs' won't be fixed, because their software hasn't been designed for what you are trying to do.. (which was - surprise, surprise - arbitrage..) Just as they don't like using their 'pipes' the way they do (which is frantically), they won't let you use their software to automate (or even monitor) something that actually works. But given the amount of money these guys are paid (Mr Malik comes to mind, these are unlikely to be just bugs... But I still think this is the best broker to learn how to trade, precisely due to this conflict of interest with its proprietary trading group.. but at some point it is time to graduate.. if you can't beat them, join them! Changing the subject completely.. did you know that the UK's Financial Services Authority has just been scrapped...?

is anybody at IB care about this nonsense? of you just don't give a shit about your customers? i've see it every single day on many stocks. is it hard to fix or something? i would appreciate an explanation about this issue from IB CS. i would also appreciate,if someone from IB can explain to me -why we having this problem with 100's for TWO FUCKING YEARS ALREADY! you keep releasing one build after another with more and more shit that make no sense,but nobody gives the shit about properly displayed data. how to fuck you can move on to some new,if old problems are not fixed for YEARS!!!
