Quote from def:
You couldn't be further off the mark and certainly haven't spent a second reading the 606 routing stats that all brokers are required to present to the SEC. Nor have you read the independent reports that show IB provides 28 cents per 100 shares net dollar price improvement over the industry average of -0.03. If IB was doing as you suggest, we certainly wouldn't be providing the superior executions that we in fact do provide.
Almost all of the orders I make that are marketable are reported as filled via "smart". I assume, but perhaps I should not, that these orders are filled by IB's market maker branch, Timber Hill and they are able to do this profitably.
This is not a bad thing. TH provides liquidity at the NBBO or better. I may not always be happy with the fills I get, but after reviewing the price action, I have never found a fill that looks to be incorrect. They are always fair and that is all that I can ask for.
The fills I get on orders reported as filled via "smart" are almost always for sub penny amounts.
So, are you saying that IB's restriction on routing via the API is not because smart orders are more profitable for IB? They should be much more profitable.
If so, then why does it cost more to direct an API order?
