Dave:
A couple things about the limit orders:

1:  When a customer opens up the limit order box, I think the time open 
should default to 12 hours.  We want the orders open as long as possible.  
Now, it is more work to keep the order open for 12 hours than for 1 hour.  
Traditionally, limit orders are a day order, good for the entire trading 
session unless specified otherwise.  

2.  Today Pete had 13,000/ day on his bid because he was hit for small size.  
When I tried to place a limit order, the quantity had to be in 5,000 
increments of 13,000 (i.e. 3000, 8000, 18000...).  I could not overwrite the 
quantity to be 15,000.  

3.  Everytime a limit order is placed, an error message occurs on the system 
saying error trade, price not available.

4.  Is there a way to modify a limit order, such as changing the price, 
without canceling it and resubmitting a new one?  If not, this would be a 
valuable feature.

Thx,
John
