Subject: Re: IB Transaction Cost Analysis
I'm pretty sure I'll try that some time, perhaps soon. There are a couple points of concern. One is that many SiPro screen picks do not trade a lot of volume.

For my smaller volume SIPro picks, I have been using Vanguard and limit orders. For buys, I place the limit at the ask. If the spread between bid and ask is more than a couple of cents, my execution price is usually better than my limit price. Similar experience with selling, execution price generally better than the limit price. I have not tried this at IB as the screen I use at IB is for very liquid stocks and I trade market orders.
