Yes, I have noticed the comments that paint IB in a less than favorable light. Some of them I agreed with - and they resulted in improvements we made to our offering - while with others I did not. I asked the question, because your post seems to imply that IB - the tough price leader -...

What fallout?

Before entering into a combination trade involving stock options, you can make a very good guess as to whether or not you are likely to get assigned: - the calls get exercised on the day before the stock goes ex-dividend - this means it is 4 days out of 252; further, the calls have to be in...

This will be changed in the near future.

If you place a marketable (i.e. immediately executable order), then you are taking liquidity. e.g. the market bid is 37.00 and the market ask is 37.02; if you submit a market order to buy, or a limit order to buy w/ a price of 37.02 or higher, then you are taking liquidity. The orders that...

The minimum price increment is 0.00005. No advance notice was given other than the response to a question in this forum last week.

This whole thing was a glitch. It happened, because two of our liquidity providers started sending us quotes rounded to 1/2 a pip. Our compression software was not expecting it, hence to displaying difficulties. We are hoping to having it fixed for tomorrow. Until the end of the week we...

Revealing the identity of the liquidity providers should not be all that helpful to you. Even if you know their name, if they wish, they can still decide not to honor their quote (albeit it is a lot less likely in case of the big banks). Think of the biggest banks in the FX dealing, and I really...

I say that you really seem to like the smileys, but seriously: The language of the agreements is prepared by our legal counsel and I am not qualified to discuss with you whether or not the wording should be different. If you find our customer agreement objectionable, then perhaps you...

I found where you are copying it from. So let me copy and paste the whole paragraph: B. IB cannot and does not warrant or guarantee that every Customer order will be executed at the best posted price. Among other things, IB may not have access to every market at which a particular product...

1) Indeed, currently IB users we have access to 4 MAJOR liquidity providers and 1 smaller one. We are currently interfacing with another MAJOR one. On top of that, IB users can trade with each other at or in between the liquidity providers quotes. 2) Why should they be disclosed? 3) I...

Correction: Only the orders with zero offset on NASDAQ stocks roll back. The orders on listed stocks don't. Since we send the non-marketable orders to the NYSE and we found NYSE to be unreliable in representing the orders in their BBO, we could not make the roll-back work to our...

Highest round-lot. You can only TAKE liquidity when you trade w/ TMBR.

The orders with zero offset do roll back. The orders with positive offset do not.

Charting of the mid implied vol is in the works.

No, they are not the same. You need to use the latest TWS to get the latest and best simulation. Further, we are still improving both the back- and front- ends.

I have checked with Mike Domka; unfortunately, he does not recall giving out our speed statistics to anyone. Would you mind PM-ing me the data that you have about us and how it compares with the best broker you found? I would really like to understand how you concluded that we are too slow for...

Yes, it was fixed.

IB takes the latency issues seriously. We put a lot of effort into optimizing the speed of the various components of our order routing infrastructure. It is in our best interest to do so for at least three different reasons: We also recognize the importance of differentiating the fully...
