I used to have cable and DSL in case one went down. It wasn't worth having both. I got rid of the DSL. I figured if a telephone pole was knocked down from a storm or car accident, both the cable, DSL and telephone would be out.

So, I have two computers running at all times with battery backups. Both have my initial trading broker software and a backup broker to hedge.

I have my cell phone ready to go in case I lose cable service and regular telephone.

I also enter a stop market order as soon as I enter a position in case all else fails.

I will not trade with such a large position that I'd be out of business if we got a 911 style attack at the CBOT . It's a sad reality. If it were to happen, you can never know about if, when, and at what price the market would open.
Something like this would put the exchange {and traders} out of business for a long time.
