Another ill-informed post. IB doesn't internalize. Odd lots are a different issue which and catering to those trading less than 100 shares isn't our main focus. IB SMART doesn't route multiple working orders at different exchanges as it needs to avoid overfills. However, it will move orders from one routing venue to another if it can achieve a better fill. The execution and price improvement stats are readily available and the latest independently audited stats show that IB's price improvement for US shares was 27 cents better per hundred shares than the industry.
Can I intentionally park orders in those dark pools you mention?
