Hi Dave,
To answer your first question about order routing, I generally use ARCA, which is probably similar to IB's BEST order routing. ARCA first looks for an order match within its own order book, but then goes out to the other ECN books, and finally the NYSE if it cannot find any matches. Using ARCA usually enables me to get a decent fill, except with ETFs that have wide spreads (such as RTH, PPH, or TTH). In those cases, I just use limit orders.
I can't tell you why your order took so long to get executed because I am not familiar with the design of IB's BEST routing. Perhaps a call to them would be helpful.
As for SMH, Peter answered your question well. SMH will generally follow the SOX, but the components are not exactly the same. Therefore, you will sometimes have a discrepancy. I recommend you check out www.holdrs.com to see the exact components of SMH. You will then know what to expect with movement of SMH, based on the direction of the leading stocks.
As for MMs not playing games on the bid/ask, I cannot tell you that this does not happen. However, my point was simply that it is irrelevant because an ETF is always going to move in correlation to the exact prices of the underlying stocks that comprise it. Therefore, even if there are no trades going off, the bid/ask will rise in proportion to the fair value of the ETF. Otherwise, arbitrage traders would take advantage of the discrepancy.
Thanks for the reply, Deron
Some comments and one question...
I will relook at IB's BEST order flow sequencing. I know it is much more than simply trying ARCA internally first. With Nasdaq stocks, I didn't need to know the BEST order fill sequencing - if my limit order was at the inside market, I was filled in 1 second (unless the market immediately moved away from me). On several occasions with SMH, if the best bid or offer was other than Island, my order has sat there for seconds, even when the market didn't move. This isn't an IB Best order routing issue - I suspect this is an unavoidable situation with ETF's (vs Nasdaq stocks) with specialists now involved. It seems I now have to think about order routing, whereas I didn't before.
Related to this, it seems that Island bids/offers do not appear in Level 2 together with the exchange quotes (unlike nasdaq stocks, where the best Island bid/offer appeared under MMID cinn). Now it seems one needs to watch Level 2, plus keep the Island book open (and in your case, the ARCA book). All in all, I can see how trading ETF's favors a slightly longer term approach, where instant in an out isn't as important as in day trading. That's fine, I'll just have to learn to deal with it.
Regarding SOX as a leading leading indicator for SMH, I understand how SOX and SMH components differ. Just knowing the general direction of key SMH components seems too general though, and not many people have enough monitors or eyes to watch the charts of the top SMH components. Maybe a watch list with top SMH components and other top semis, sorted by % gain would work. If the SMH components had the best % gain, then SOX should be a leading indicator, otherwise, not so leading.
My question was regarding your last paragraph. You said " .. even if there are no trades going off, the bid/ask will rise in proportion to the fair value of the ETF". Are you saying that if the composite prices of the SMH components advance a certain amount, that the inside market for SMH will automatically rise a related amount, i.e automatically lifting all offers necessary to rise as much as needed to align with its components? Some person (or AMEX?) has to be taking the quoted offers? Can you clarify how that works?
Thanks again for your insights
