Stocks and the next big incident?

As one of the key facts relating to inside and prior knowledge of 9/11 was the increase in trading, does anyone know of sites that dealy primarily with the stock market and "unusual tradings"? Just thought it may be something to watch as well. My knowledge of the stock market is somewhat limited, but i'm sure it won't take a genius to put two and two together with a little help.

There was a post recently about current trading which seems to be worth keeping an eye on, but i can't find it. Any pointers much appreciated.

Cancel that, i'll keep an eye on PTS in the economic section. Unless anyone else has any better ideas?

cx you can go to any number of sites and get free quotes and check volume. if you watch a variety of stocks in businesses that you think will be impacted by an attack (airlines for example) then, when the volume increases heavily you can see that something might be afoot.

Thanks for that
