I keep getting the t&s window going all red - telling me every trade is below the bid. ( my properties preference)
If I change a property it seems to 'reset' but sometimes only for a short while.
I had this before and changed my IB TWS to the one you recommended but now I get it on 2 different machines - one using XP the other Vista.
If I close the T&S window it usually rights itself as well.
There is no pattern to this behaviour - it just happens in high volume periods, low volume periods - etc.
My symbol is FDAX 03-10 5 minutes.
It can go hours working just fine then I have to close and open 5 windows in 10 mnutes.
