Peter,

There are two quote problems that could be solved by your software.
1. It is a common occurrence that shortly after 4:00 PM ET spread on NYSE stocks widens (bid drops and ask goes up). Your system should freeze quote updates at 4:00 sharp. Note that this problem also affects the account value figures.
2. When a stock is halted, its bid and ask disappear. This causes a value of a long position in that stock to be shown as 0 in the portfolio summary. I don't think you want to cause any heart attacks so you may want to show that stock's value as HALTED or maybe use the last price before halt.

These two problems can possibly cause a false margin call so they aren't just cosmetic.
